ABSTRACT

The calibration of chromone reference extract(CRE) was conducted and a quality control method of Saposhnikoviae Radix(SR) was established based on CRE. Meanwhile, the quality control system of SR was improved and the feasibility of using reference extract as a substitute for single reference substance in quality control of Chinese medicine was discussed. In this study, the content of the prepared CRE was calibrated with prim-O-glucosylcimifugin, cimifugin, 4'-O-β-D-glucosyl-5-O-methylvisamminol, and secO-glucosylhamaudol as indicators. Subsequently, an HPLC analytical method was developed to determine the content of four chromones in 20 batches of SR samples based on the CRE with known content as the standard substance. T-test was used for the comparison of the determination results of the two methods(single chemical component and CRE as reference substances, respectively), and the P values of prim-O-glucosylcimifugin, cimifugin, 4'-O-β-D-glucosyl-5-O-methylvisamminol, and sec-O-glucosylhamaudol were 0. 16,0. 39, 0. 14, and 0. 42. The results demonstrated that there was no significant difference between the two methods. This study initially verified the feasibility that the CRE could be used as a substitute for single reference substance in quality control of SR. In conclusion,this study is expected to provide a scientific basis and a new research model for the application of reference extract in the quality control of Chinese medicine.

ABSTRACT

This research was used with high performance liquid chromatography(HPLC), combined with information entropy-response surface method(RSM) to investigate the ethanol concentration, extraction time, liquid-to-material ratio. Taking the content of four chromogens as evaluation indexes, the weight coefficients of each index were given, and the comprehensive score was calculated to optimize the extraction process. Then, prim-O-glucosylcimifugin was used as the reference, the relative calibration factors(RCFs) of cimifugin, 4'-O-β-D-glucosyl-5-O-methylvisamminol and sec-O-glucosylhamaudo to prim-O-glucosylcimifugin were calculated respectively. The contents of four components in Saposhnikoviae Radix were determined by both external standard method(ESM)and quantitative analysis of multi-components by single marker(QAMS) method, and the results were compared. At last, combined with principal component analysis(PCA) and orthogonal partial least squares discriminant analysis(OPLS-DA) to evaluate the quality of the Saposhnikoviae Radix in different production areas. The optimal extraction process parameter of the Saposhnikoviae Radix was as follows: liquid-to-material ratio is 60∶1(mL·g~(-1)), extraction time is 35 min, and ethanol concentration is 70%. The repeatability of the RCFs was perfect, and the results calculated by the QAMS were consistent with the results from the ESM. The stoichiometric results indicate that there are obvious differences in the distribution of Saposhnikoviae Radix in different production areas, and cimifugin and prim-O-glucosylcimifugin are the characteristic compounds that cause this difference. In this study, the optimal extraction process is stable and feasible, and the method of QAMS is accurate and reliable. From the perspective of four chromogens, there are differences in the quality of the Saposhnikoviae Radix in different production areas. Therefore, the established extraction process combined with the method of QAMS can be used to evaluate the quality of Saposhnikoviae Radix and provide a scientific basis for the quality control of Saposhnikoviae Radix.

ABSTRACT

Culantro de monte (Eryngium foetidum L.) is a biennial herb of tropical origin very frequent in America, Africa and the Caribbean. With the arrival of Europeans in the fifteenth century, it managed to be distributed to various locations in Asia and Europe. The present study was carried out in the San Antonio de Padua community in the Province of Los Ríos - Ecuador to collect information, through interviews with the residents, regarding the nomenclature and uses of this aromatic herb. It was found that 52% of the interviewees mention a nutritional use, especially as a condiment for fish soup, buns and stews, while 26% say they use this plant for medicinal purposes in infusions to cure stomach and joint pain. The variety of metabolites that it possesses, such as eryngial (E-2-Dodecenal), extends its range of applications in modern medicine. We concluded that the transfer of ethnobotanical information still remains in the community, but the young generations are unaware of several of this plant's applications.

ABSTRACT

The aim of this paper was to investigate the effect of Schizonepetae Herba and Saposhnikoviae Radix(wind medicine) on the expression of AQP4 and AQP8 in colonic mucosa in rats with ulcerative colitis(UC). A total of 35 healthy SD male rats were randomly divided into normal group(gavaged with normal saline), DSS model group, as well as low, middle, and high dose wind medicine groups(Schizonepeta and Saposhnikovia 1∶1, gavaged at dosages of 6, 12, and 24 g·kg~(-1)·d~(-1)), with 7 in each group. UC rat model was established by free drinking of 3% dextran sulphate sodium(DSS) solution for 10 days. At the end of the 10 th day after the treatment, mice were put to death to collect colonic mucosa. The length of colon was measured; the colonic mucosal injury index(CMDI) and pathological changes of colon were observed. ELISA method was used for measuring the content of serum IL-1, IL-8, and immunohistochemical method was used to measure AQP4, AQP8 protein expressions in colon mucosa. The expressions of AQP4, AQP8 mRNA were measured by Real-time PCR. As compared with the normal group, the length of colon tissue was significantly reduced(P<0.01), CMDI scores and pathological scores were significantly increased(P<0.01), the levels of serum IL-1 and IL-8 were significantly increased(P<0.05) in model group; the immunohistochemical results showed that the protein expressions of AQP4, AQP8 were lower; the color was light yellow or brown; AQP4, AQP8 mRNA expressions in colon mucosa were significantly decreased in model group(P<0.01). CMDI scores, pathological scores, and the levels of serum IL-1, IL-8 in high, middle, low dose wind medicine groups were obvious lower than those in the model group(P<0.01 or P<0.05); the protein expressions of AQP4, AQP8 were higher; the color was chocolate brown or dark brown; the length of colon tissue, and the expressions of AQP4, AQP8 mRNA were obvious higher in wind medicine groups(P<0.01 or P<0.05). Schizonepetae Herba and Saposhnikoviae Radix could significantly improve the symptoms and histopathology of UC model rats and accelerate the intestinal mucosal healing. The mechanism may be related with up-regulating the expression level of AQP4 and AQP8 in colonic mucosa.

ABSTRACT

To clarify the difference of soil moisture characteristics between mixed broad leaf-conifer forest soil and artificial cultivation of Notopterygium incisum, the HYPROP system and the dew point potential meter were used to determine soil water retention curves(SWRC) for samples of two horizons(i.e. 2-7 cm, 10-15 cm). The basic physical and chemical properties of soil and its water characteristic parameters were also determined. The result showed as fllows:①The bulk density of mixed coniferous-broad leaf forest soil was between 0.33 and 0.52 g·cm~(-3), significantly lower than the corresponding value of field soil(1.01-1.18 g·cm~(-3))(P<0.05), While the organic matter content was significantly higher than the corresponding value of field soil(P<0.05). ②The saturated water content(θ_s), field water holding capacity(θ_(FC)) and Water that can be effectively utilized by plants(θ_(PAC)) of mixed coniferous-broadleaved forest soil were significantly higher than the corresponding value of field soil(P<0.05), while the retained water content(θ_r) value that cannot be effectively utilized by plants was significantly lower than that of field soil(P<0.05). ③The values of structural porosity(0.13-0.24 cm~3·cm~(-3)) and Matrix porosity(0.34-0.44 cm~3·cm~(-3)) of mixed coniferous-broadleaved forest soil were higher than the corresponding values of field soil. Therefore, with low bulk density and high content of organic matter, mixed coniferous-broadleaved forest soil can store more water in soil in the form of effective water to meet the needs of plants for water, thus possibly forming high quality medicinal materials of Notopterygii Rhizoma et Radix. In conclusion, the results of this study can provide theoretical basis guidance for soil structure improvement and water management to form high quality medicinal materials in the artificial cultivation of N. incisum.

ABSTRACT

Abstract The aims of this research were: evaluate the chemical composition and the cytotoxicity of the Cuminum cyminum (cumin), Anethum graveolens (dill), Pimpinella anisum (anise) and Foeniculum vulgare (fennel) essential oils, as well as their antifungal activity in vitro against ten Candida spp. isolates. The chemical composition of the oils was analyzed by means of gas chromatography coupled with mass spectrometry (GC/MS). The cytotoxicity assays were performed, using the cell proliferation reagent WST-1 in L929 mouse fibroblasts (20x103 well-1). The determinate the Minimum Inhibitory Concentration (MIC), was performed through the Broth Microdilution technique (CLSI). The chemical main components were the cuminaldehyde (32.66%) for cumin, carvone (34.89%) for the dill, trans-anethole (94.01%) for the anise and anethole (79.62%) for the fennel. Anise and fennel did not were cytotoxic in all the tested concentrations, however the cumin oil was cytotoxic in the concentration of 20 mg.mL-1 and the dill in the concentrations of 20 and 8 mg.mL-1. All yeasts were susceptible against the evaluated essential oils. Cumin presented the lowest MIC against yeasts. We concluded that all the essential oils presented inhibitory action against Candida spp., and C . cyminum, P. anisum and F. vulgare were not cytotoxic in the same minimum inhibitory concentrations for the fungi.

ABSTRACT

ABSTRACT Ducrosia anethifolia has been recommended as a remedy for neurological disorders. However, the anticonvulsant effects of D. anethifolia essential oil (DAEO) and its major constituent α-pinene have not yet been clarified. Methods: A rat model of pentylenetetrazole (PTZ)-induced convulsions was used. Oxidant and antioxidant parameters were assayed in the temporal lobe. Results: The data showed that DAEO (50, 100 and 200 mg/kg, i.p.) and α-pinene (0.2 and 0.4 mg/kg i.p.) delayed the initiation time, and reduced the duration of myoclonic and tonic-clonic seizures following PTZ injection. The PTZ produced oxidative stress so that malondialdehyde and hydrogen peroxide levels were increased and catalase and peroxidase activity decreased. Pretreatment with DAEO and α-pinene significantly inhibited the above-mentioned enzymatic changes in PTZ-treated animals. Conclusion: The results suggest that α-pinene, at teast in part, was responsible for the induction of the anticonvulsant and antioxidant effects of DAEO in rats.


RESUMO A Ducrosia anethifolia tem sido recomendada como remédio para os distúrbios neurológicos. No entanto, os efeitos anticonvulsivantes do óleo essencial de Ducrosia anethifolia (DAEO) e do seu principal constituinte atfa-pineno (α-pineno) ainda não foram clarificados. Métodos: Foi utilizado um modelo de rato de convulsões induzidas por pentilenotetrazol (PTZ). Os parâmetros oxidante e antioxidante foram ensaiados no lobo temporal do cérebro. Resultados: Os dados mostraram que DAEO (50, 100 e 200 mg / kg, i.p.) e α-pineno (0,2 e 0,4 mg / kg i.p.) retardaram o tempo de iniciação e reduziram a duração das crises mioclônicas e tônico-clônicas após a injeção de PTZ. O PTZ produziu estresse oxidativo, de modo que os níveis de malondialdeído (MDA) e de peróxido de hidrogênio aumentaram e a atividade da catalase e da peroxidase diminuiu. O pré-tratamento com DAEO e α-pineno inibiu significativamente as alterações enzimáticas mencionadas em animais tratados com PTZ. Conclusão: O resultado sugere que α-pineno, peto menos em parte, é responsável peta indução dos efeitos anticonvulsivantes e antioxidantes da DAEO em ratos.

ABSTRACT

Trachyspermum ammi (T. ammi) has been used in folk medicine as anti-inflammatory, antipyretic, antibacterial, antifungal agent. The present study was conducted to investigate the protective effect of Trachyspermum ammi (T. ammi) essential oil against CC14- induced nephrotoxicity in mice. Thirty-five mice were divided into five groups as follows; positive control received olive oil 1 mL/ kg/ip, negative control received CC14 1 mg/kg/ip + 0.5 mL distilled water orally and tree treatment groups which received CC14 similar to the negative control and 200, 800 and 1600 µg/kg of T. ammi essential oil, respectively. All treatments were done twice a week (Saturday and Wednesday) for 45 days. On the last day, blood was sampled for urea and creatinine assessment and the left kidney was removed for stereological estimations. Essential oil of T. ammi at high dose significantly (p ≤ 0.05) decreased serum levels of creatinine and urea in comparison with CC14-treated group. Total volume of the kidney, cortex, proximal convoluted tubules (PC), glomerulus, vessels and interstitial tissue as well as total length of PC and vessel were significantly (p ≤ 0.05) increased following CC14 administration and were restored toward normal levels at high dose of T. ammi. Also, high dose of T. ammi improved glomerular loss significantly (p ≤ 0.05) as compared with CC14-treated group. Due to the chemical composition of T. ammi essential oil such as tymol, p-cymene, γ-terpinene which are antioxidant, it can be concluded that the essential oil of T. ammi can ameliorated renal injury induced following CC14 toxicity via its antioxidant components.


En la medicina popular se ha utilizado el aceite esencial de Trachyspermum ammi (T. ammi) como agente antiinflamatorio, antipirético, antibacteriano y anti fúngico. El presente estudio se realizó para investigar el efecto protector de Trachyspermum ammi (T. ammi) aceite esencial contra la nefrotoxicidad inducida en ratones. Treinta y cinco ratones fueron divididos en cinco grupos de la siguiente manera; el control positivo recibió 1 mL / kg / ip de aceite de oliva, el control negativo recibió 1 mg / kg / ip + 0,5 mL de agua destilada por vía oral y grupos de tratamiento arbóreo que recibieron un control similar al negativo y 200, 800 y 1600 mg / kg de T. aceite esencial de T. ammi, respectivamente. Todos los tratamientos se realizaron dos veces por semana (sábado y miércoles) durante 45 días. En el último día de tratamiento, se tomaron muestras de sangre para evaluar la urea y la creatinina, y se extrajo el riñón izquierdo para realizar estimaciones estereológicas. El aceite esencial de T. ammi a dosis altas significativamente (p ≤ 0,05) disminuyó los niveles séricos de creatinina y urea en comparación con el grupo tratado. El volumen total del riñón, la corteza, los túbulos contorneados proximales (PC), el glomérulo, los vasos y el tejido intersticial, así como la longitud total de la PC y el vaso aumentaron significativamente (p ≤ 0,05) después de la administración y se restablecieron a niveles normales con dosis altas de T. ammi. Además, una dosis alta de T. ammi mejoró significativamente la pérdida glomerular (p ≤ 0,05) en comparación con el grupo tratado. Debido a la composición química del aceite esencial de T. ammi como timol, p-cimeno, 𝛾-terpineno con propiedades antioxidantes, se puede concluir que el aceite esencial de T. ammi puede mejorar la lesión renal inducida después de la toxicidad a través de sus componentes antioxidantes.

ABSTRACT

Halophytes are expected to possess abundant secondary metabolites and various biological activities because of habitat in extreme environments. In this study, we collected 14 halophytes (Asparagus oligoclonos, Calystegia soldanella, Carex pumila, Chenopodium glaucum, Elymus mollis, Glehnia littoralis, Limonium tetragonum, Messerschmidia sibirica, Rosa rugosa, Salsola komarovii, Spergularia marina, Suaeda glauca, Suaeda maritima, and Vitex rotundifolia) native to Korea and compared their total polyphenol contents, antioxidant and anti-inflammatory activities. The total polyphenol contents of R. rugosa (27.28%) and L. tetragonum (13.17%) were significantly higher than those of the other 12 halophytes and L. tetragonum, R. rugosa, and M. sibirica showed significantly greater antioxidant activities than the other 11 halophytes, as determined by DPPH (2,2-diphenyl-1-picrylhydrazyl). A. oligoclonos, E. mollis, and C. pumila showed significantly greater anti-inflammatory activities than the other 11, as determined by NO (Nitric oxide) and PGE₂ (Prostaglandin E₂) levels. In contrast, these three extracts had normal and low total polyphenol contents among the 14 halophytes. Consequently, the total polyphenol content in the 14 studied halophytes appeared to be related to antioxidant, but not anti-inflammatory activity levels.

ABSTRACT

<p><b>Background</b>Glehnia littoralis has been used for traditional Asian medicine, which has diverse therapeutic activities. However, studies regarding neurogenic effects of G. littoralis have not yet been considered. Therefore, in this study, we examined effects of G. littoralis extract on cell proliferation, neuroblast differentiation, and the maturation of newborn neurons in the hippocampus of adult mice.</p><p><b>Methods</b>A total of 39 male ICR mice (12 weeks old) were randomly assigned to vehicle-treated and 100 and 200 mg/kg G. littoralis extract-treated groups (n = 13 in each group). Vehicle and G. littoralis extract were orally administrated for 28 days. To examine neurogenic effects of G. littoralis extract, we performed immunohistochemistry for 5-bromo-2-deoxyuridine (BrdU, an indicator for cell proliferation) and doublecortin (DCX, an immature neuronal marker) and double immunofluorescence staining for BrdU and neuronal nuclear antigen (NeuN, a mature neuronal marker). In addition, we examined expressional changes of brain-derived neurotrophic factor (BDNF) and its major receptor tropomyosin-related kinase B (TrkB) using Western blotting analysis.</p><p><b>Results</b>Treatment with 200 mg/kg, not 100 mg/kg, significantly increased number of BrdU-immunoreactive () and DCX cells (48.0 ± 3.1 and 72.0 ± 3.8 cells/section, respectively) in the subgranular zone (SGZ) of the dentate gyrus (DG) and BrdU/NeuN cells (17.0 ± 1.5 cells/section) in the granule cell layer as well as in the SGZ. In addition, protein levels of BDNF and TrkB (about 232% and 244% of the vehicle-treated group, respectively) were significantly increased in the DG of the mice treated with 200 mg/kg of G. littoralis extract.</p><p><b>Conclusion</b>G. littoralis extract promots cell proliferation, neuroblast differentiation, and neuronal maturation in the hippocampal DG, and neurogenic effects might be closely related to increases of BDNF and TrkB proteins by G. littoralis extract treatment.</p>

ABSTRACT

To investigate the adaptive mechanism of Notopterygium incisum to water changes, one-year-old seedlings were used as test materials. The characteristics of growth, physiology, and active ingredients of N. incisum were studied at different soil water content by pot experiments. The result showed that: ①The water content at 100% field capacity is conducive to the growth and accumulation of biomass of N. incisum. The leaf length, petiole length, petiole diameter, root diameter, root length and biomass of underground dry of N. incisum were all significantly increased at the 100% field capacity, and they slightly declined at 70% field capacity. 20% field capacity could not provide the necessary water to growth of N. incisum, all N. incisum withered and died. ②With the extension of moisture treatment time, the relative content of chlorophyll (SPAD) in leaves and the activity of peroxidase (POD) in rhizome showed a trend of increasing firstly, decreasing then; the tendency of activity of superoxide dismutase (SOD) in rhizome increased; the content of malondialdehyde (MDA) in rhizome decreased firstly and increased then;. For the late test, the SPAD value, the activity of POD and SOD in N. incisum at the 40% field capacity were lower than 70% field capacity and 100 field capacity, while the content of MDA in rhizome were higher than 70% field capacity and 100% field capacity. ③ At 70% field capacity, the active ingredients accumulated most in the N. incisum. At the 70% field capacity, the notopterol and isoimperatorinwerehigher than100 field capacity and 40 field capacity. In summary, the soil water content at 70%-100% field capacity would contribute to the growth and accumulation of active ingredients of N. incisum.

ABSTRACT

Saposhnikovia divaricata is a valuable Chinese medicinal herb; the transformation from vegetative growth to reproductive growth may lead to the decrease of its pharmacological activities. Therefore, the study of bolting and flowering for Saposhnikovia divaricata is warranted. The present study aimed to reveal differentially expressed genes (DEGs) and regularity of expression during the bolting and flowering process, and the results of this study might provide a theoretical foundation for the suppression of early bolting for future research and practical application. Three sample groups, early flowering, flower bud differentiation, and late flowering (groups A, B, and C, respectively) were selected. Transcriptomic analysis identified 67, 010 annotated unigenes, among which 50, 165 were differentially expressed including 16, 108 in A vs B, and 17, 459 in B vs C, respectively. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway functional classification analysis were performed on these differentially expressed genes, and five important pathways were significantly impacted (P ≤ 0.01): plant circadian rhythm, other glycan degradation, oxidative phosphorylation, plant hormone signal transduction, and starch and sucrose metabolism. Plant hormone signal transduction might play an important role in the bolting and flowering process. The differentially expressed indole-3-acetic acid (IAA) gene showed significant down-regulation during bolting and flowering, while the transport inhibitor response 1 (TIR1) gene showed no significant change during the bolting process. The expression of flowering related genes FLC, LYF, and AP1 also showed a greater difference at different development stages. In conclusion, we speculate that the decrease in auxin concentration is not caused by the degrading effect of TIR1 but by an alternative mechanism.

ABSTRACT

Notopterygium incisum (QH) has been used for the treatment of rheumatoid arthritis (RA), and volatile oils may be its mainly bioactive constituents. The present study was designed to analyze the volatile compounds in QH and to determine the anti-arthritic capacity of Notopterygium volatile oils and the potential mechanism of action. The volatile compounds analysis was conducted by GC-MS. The anti-arthritic capacity test of the volatile oils was conducted on adjuvant-induced arthritis (AIA) rats. The anti-inflammatory property was tested in NO release model in RAW 264.7 cells. Endothelial cells were used to evaluate the anti-proliferative and anti-tube formative effects. 70 compounds were analyzed by GC-MS in the volatile oils. Notopterygium volatile oils weakened the rat AIA in a dose-dependent manner (2, 4, and 8 g crude drug/kg). The NO production by RAW 264.7 was decreased by more than 50% in Notopterygium volatile oils (5, 15, and 45 μg·mL) pretreated groups. Notopterygium volatile oils also inhibited EAhy926 cell proliferation and further delayed EAhy926 cell capillary tube formation in a concentration-dependent manner. The anti-NO productive, anti-proliferative, and anti-tube formative effects of Notopterygium volatile oils strongly suggested that the therapeutic effect of QH in AIA might be related to the potent anti-inflammatory and anti-angiogenic capacities of the volatile oils.

ABSTRACT

Saposhnikovia divaricata is a valuable Chinese medicinal herb; the transformation from vegetative growth to reproductive growth may lead to the decrease of its pharmacological activities. Therefore, the study of bolting and flowering for Saposhnikovia divaricata is warranted. The present study aimed to reveal differentially expressed genes (DEGs) and regularity of expression during the bolting and flowering process, and the results of this study might provide a theoretical foundation for the suppression of early bolting for future research and practical application. Three sample groups, early flowering, flower bud differentiation, and late flowering (groups A, B, and C, respectively) were selected. Transcriptomic analysis identified 67, 010 annotated unigenes, among which 50, 165 were differentially expressed including 16, 108 in A vs B, and 17, 459 in B vs C, respectively. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway functional classification analysis were performed on these differentially expressed genes, and five important pathways were significantly impacted (P ≤ 0.01): plant circadian rhythm, other glycan degradation, oxidative phosphorylation, plant hormone signal transduction, and starch and sucrose metabolism. Plant hormone signal transduction might play an important role in the bolting and flowering process. The differentially expressed indole-3-acetic acid (IAA) gene showed significant down-regulation during bolting and flowering, while the transport inhibitor response 1 (TIR1) gene showed no significant change during the bolting process. The expression of flowering related genes FLC, LYF, and AP1 also showed a greater difference at different development stages. In conclusion, we speculate that the decrease in auxin concentration is not caused by the degrading effect of TIR1 but by an alternative mechanism.

ABSTRACT

PURPOSE: Glehnia littoralis has been reported to have several pharmacological properties but no in vivo reports describing the protective effects of this plant on α-amanitin-induced hepatotoxicity have been published. α-Amanitin is a peptide found in several mushroom species that accounts for the majority of severe mushroom poisonings leading to severe hepatonecrosis. In our previous in vitro study, we found that α-amanitin induced oxidative stress, which may contribute to its severe hepatotoxicity. The aim of this study was to investigate whether Glehnia littoralis acetate extract (GLEA) has protective antioxidant effects on α-amanitin-induced hepatotoxicity in a murine model. METHODS: Swiss mice (n=40 in all groups) were divided into four groups (n=10/group). Three hours after giving α-amanitin (0.6 mg/kg, i.p.) to the mice, they were administered silibinin (50 mg/kg/d, i.p.) or Glehnia littoralis ethyl acetate extract (100 mg/kg/d, oral) therapies once a day for 3 days. After 72 hours of treatment, each subject was killed, cardiac blood was aspirated for hepatic aminotransferase measurement, and liver specimens were harvested to evaluate the extent of hepatonecrosis. The degree of hepatonecrosis was assessed by a pathologist blinded to the treatment group and divided into 4 categories according to the grade of hepatonecrosis. RESULTS: GLEA significantly improved the beneficial functional parameters in α-amanitin-induced hepatotoxicity. In the histopathological evaluation, the toxicity that was generated with α-amanitin was significantly reduced by GLEA, showing a possible hepatoprotective effect. CONCLUSION: In this murine model, Glehnia littoralis was effective in limiting hepatic injury after α-amanitin poisoning. Increases of aminotransferases and degrees of hepatonecrosis were attenuated by this antidotal therapy.

ABSTRACT

Saposhnikoviae divaricata (Turcz.) Schischk (SD) is a traditional Chinese herb commonly used to treat clinical conditions such as rheumatism and allergic rhinitis. This review article evaluates a collection of works on in vitro and biochemical studies of SD. The discourse on the diverse class of chromones and coumarins in SD offers an insight to the pharmacological effects of these bioactive constituents as anti-inflammatory, analgesic, immunoregulatory, antioxidative, and anti-proliferative agents. It is highlighted that there is a structural relationship between the constituents and bioactive activities, which in effect provides a valid reasoning and reaffirm the use of SD in the treatment of the pathologies in Chinese medicine.

ABSTRACT

PURPOSE: Glehnia littoralis has been used to treat ischemic stroke, phlegm, cough, systemic paralysis, antipyretics and neuralgia. The pharmacological mechanisms of Glehnia littoralis include calcium channel block, coumarin derivatives, anticoagulation, anti-convulsive effect, as well as anti-oxidant and anti-inflammatory effects. Alpha-amanitin (α-amanitin) is a major toxin from extremely poisonous Amanita fungi. Oxidative stress, which may contribute to severe hepatotoxicity was induced by α-amanitin. The aim of this study was to investigate whether Glehnia littoralis ethyl acetate extract (GLEA) has the protective antioxidant effects on α-amanitin -induced hepatotoxicity. METHODS: Human hepatoma cell line HepG2 cells were pretreated in the presence or absence of GLEA (50, 100 and 200µg/ml) for 4 hours, then exposed to 60µmol/L of α-amanitin for an additional 4 hours. Cell viability was evaluated using the MTT method. AST, ALT, and LDH production in a culture medium and intracellular MDA, GSH, and SOD levels were determined. RESULTS: GLEA (50, 100 and 200µg/ml) significantly increased the relative cell viability by 7.11, 9.87, and 14.39%, respectively, and reduced the level of ALT by 10.39%, 34.27%, and 52.14%, AST by 9.89%, 15.16%, and 32.84%, as well as LDH by 15.86%, 22.98%, and 24.32% in culture medium, respectively. GLEA could also remarkably decrease the level of MDA and increase the content of GSH and SOD in the HepG2 cells. CONCLUSION: In the in vitro model, Glehnia littoralis was effective in limiting hepatic injury after α-amanitin poisoning. Its antioxidant effect is attenuated by antidotal therapy.
