ABSTRACT

This study aimed to investigate the effect of serum containing ginseng and Moutan Cortex on human umbilical vein endothelial cells(HUVEC) injured with hydrogen peroxide(H_2O_2). HUVEC injured with H_2O_2 were divided into 6 groups, namely blank group, model group, ginsenoside(TGG) group, total glucosides of Moutan Cortex(TGM) group, paeonol(P) group and TGG+TGM+P group. After 24 hours of co-culture with H_2O_2, the activities of succinate dehydrogenase(SDH) and Ca~(2+)-Mg~(2+)-ATP were detected by microenzyme labeling. The apoptosis rate, intracellular Ca~(2+) concentration, reactive oxygen species(ROS) and mitochondrial membrane potential(JC-1) were detected by flow cytometry. The expressions of mitochondrial apoptosis pathway-related proteins Bax, Bcl-2, cytochrome C, caspase-3 and caspase-9 were detected by Western blot. The results showed that H_2O_2 could significantly damage HUVEC, decrease the activity of SDH and Ca~(2+)-Mg~(2+)-ATP(P<0.01), while could increase the apoptosis+necrosis rate, JC-1 decline rate, ROS increase rate and Ca~(2+) concentration increase rate(P<0.01). Serum containing ginseng and Moutan Cortex could increase the activities of SDH and Ca~(2+)-Mg~(2+)-ATP to different degrees, decrease the apoptosis+necrosis rate, JC-1 decline rate, ROS increase rate and Ca~(2+) concentration increase rate(P<0.05 or P<0.01), and down-regulate the protein expressions of Bax, caspase-3, caspase-9, cytochrome C, and up-regulate the protein expression of Bcl-2. The results showed that serum containing ginseng and Moutan Cortex has a protective effect on vascular endothelial cell injury induced by ROS, and its mechanism may be related to the improvement of mitochondrial function and the inhibition of the activation of mitochondrial apoptosis pathway.

ABSTRACT

The extract rates, multicomponent content and fingerprint were determined in this study to investigate the quality diffe-rence between standard decoction of raw Paeoniae Radix Alba and fried Paeoniae Radix Alba. UPLC fingerprint was established for 17 batches of standard decoction of raw and fried Paeoniae Radix Alba, and the contents of gallic acid, catechin, albiflorin, paeoniflorin and benzoyl paeoniflorin were determined. The peak areas of standard decoction were analyzed by the independent t-test and orthogonal partial least squares discriminant analysis. There was no significant difference in extract rates between the standard decoction of raw and fried Paeoniae Radix Alba. After fried processing, the content of albiflorin increased by 0.26%, while the contents of gallic acid, catechin, paeoniflorin and benzoyl paeoniflorin decreased by 13.04%, 27.97%, 10.30% and 18.79% respectively. There were 14 common peaks in the fingerprint of standard decoction of raw Paeoniae Radix Alba, and 16 common peaks in the fried Paeoniae Radix Alba. Peak 1 and peak 3 were new ones after processing, among which the peak 3 was 5-hydroxymethylfurfural. The results showed that peak 1, peak 3, peak 11 and peak 15 were the key compounds to distinguish standard decoction of raw and fried Paeoniae Radix Alba. In conclusion, this method is stable and can be used for the study of quantity transfer and quality control in the preparation process of standard decoction, granules and other dosage forms for raw and fried Paeoniae Radix Alba, providing reference for the identification of raw and fried Paeoniae Radix Alba and related preparations.

ABSTRACT

Trace metals deficiency or excess are associated with the etiology and pathogenesis of rheumatoid arthritis(RA). Aconiti Radix Cocta(A) and Paeoniae Radix Alba(B) are commonly used together for the treatment of RA. In this study, we aim to determine anti-arthritic-related metal bioavailability in the compatibility of herb A and B for avoiding metal deficiency or excess, and optimize the combination ratio of herb A and B, accordingly. Anti-arthritic-related metal bioaccessibility were evaluated by in vitro simulator of all gastrointestinal tract(including mouth, stomach, small and large intestines), and the roles of gastrointestinal digestive enzymes and intestinal microflora were investigated. Anti-arthritic-related metal bioavailability was assessed by the affinity adsorption with liposomes. The results indicated that compatibility proportion of corresponding herbal plants, gastrointestinal digestion and microbial metabolic, which could affect metal digestion and absorption. The optimal compatibility proportion of 1 A∶1 B is recommended, according to the dose of anti-arthritic-related metal bioavailability, which is often chosen for clinical practice of RA therapy. Thus, anti-arthritic-related metal bioavailability might be the key active substances for RA treatment.

ABSTRACT

Traditional Chinese medicine is the product of clinical medication practice of the Chinese nation for thousands of years. Its material basis is the key to reveal the essence of the roles of traditional Chinese medicine, and the fundamental guarantee to solve the difficulties in the quality control of traditional Chinese medicine. However, the material basis of traditional Chinese medicine is to exert the overall pharmacodynamic effect through multi-targets, multi-approaches and mutual cooperation, resulting in unclear quality control index. In recent years, the quality control standards of traditional Chinese medicine have experienced great changes by shifting the focus from the appearance characteristics to the internal material basis, which however is limited to the control of a single com-ponent or multiple components. In other words, the intrinsic effectiveness and safety could not be guaranteed without the characteristics of the integrity of traditional Chinese medicine. With Moutan Cortex as an example, this paper analyzed the evolution of Moutan Cortex quality standards based on Chinese Pharmacopoeia, and comprehensively summarized the material basis of Moutan Cortex. Based on the theory of "component structure", this study analyzed current quality control of the material basis of Moutan Cortex and its preparations, and expounded the development trend of multi-dimensional quality control, so as to lay a foundation for establishing a more rational quality control system for traditional Chinese medicine in the future.

ABSTRACT

Guided by the theory of "component structure", we analyzed the structural characteristics of pharmacodynamical components in genuine Moutan Cortex. The compositions of organic small molecules were determined by high performance liquid chromatography(HPLC) for 20 batches of genuine Moutan Cortex and 12 batches of non-genuine Moutan Cortex. By means of similarity analysis, clustering analysis(CA), principal component analysis(PCA) and orthogonal partial least-squares discriminant analysis(OPLS-DA), the elements in structural characteristics of the pharmacodynamical components were extracted as follows: terpene glycosides components(oxidized paeoniflorin, paeoniflorin,galloyl paeoniflorin, benzoyloxy paeoniflorinand benzoyl paeoniflorin), tannin components(1,3,6-tri-O-galloside acyl glucose, pentagalloyl glucose), and phenolic acid components(methyl gallate, paeonol). The contents and quantity ratios of terpene glycoside component, tannin component and phenolic acid components in genuine Moutan Cortex were determined as 14.1, 12.5, 21.7 mg·g~(-1), 1.00∶0.89∶1.54. The contents and quantity ratios of the oxidized paeoniflorin, paeoniflorin and benzoylpaeoniflorin in the terpene glycoside components were characteristic and determined as 2.05, 7.05, 3.30 mg·g~(-1), 1.00∶3.44∶1.61. The unique structural characteristics of genuine Moutan Cortex provide scientific basis for the formulation of quality standards.

ABSTRACT

Based on the theory of "component structure", the component structure characteristics of 17 inorganic elements in 20 batches of genuine Moutan Cortex and 12 batches of non-genuine Moutan Cortex were analyzed. The analytical method of inductively coupled plasma mass spectrometry(ICP-MS) for inorganic elements in Moutan Cortex was established, and the fingerprint of inorganic elements was drawn. Through correlation analysis and principal component analysis, the constituent elements of inorganic elements in Moutan Cortex were excavated, namely characteristic elements As, Cr, Pb, Se, K, Cu and Cd. The amount and the quantity relative ratio between the components of genuine and non-genuine Moutan Cortex samples were analyzed. It was found that the amount of characteristic elements in the bulk genuine Moutan Cortex samples was 0.33, 1.42, 1.33, 0.11, 4 385.78, 4.87, 0.49 mg·kg~(-1), with the quantity relative ratio of 1.00∶4.30∶4.03∶0.33∶13 290.24∶14.76∶1.48. The amount of characteristic elements in sub-packaged genuine Moutan Cortex was 0.24, 1.96, 0.36, 0.05, 5 122.01, 4.81, 0.05 mg·kg~(-1), with the quantity relative ratio of 1.00∶8.17∶1.50∶0.21∶21 341.71∶20.04∶0.21. The unique structural characteristics of inorganic elements in genuine Moutan Cortex are studied to provide a basis for the quality control and safety evaluation of Moutan Cortex.

ABSTRACT

The aim of this paper was to study the prescription compatibility connotation in the treatment of primary dysmenorrhea(PD) and verify the mechanism as predicted by network pharmacology of Siwu Decoction(SWD). Mice PD model was constructed by using estradiol benzoate-oxytocin. PD mice were randomly divided into 8 groups, namely normal group, model group, positive group, complete formula group, Rehmanniae Radix Praeparata-free group, Paeoniae Radix Alba-free group, volatile oil-free group, Chuan-xiong Rhizoma and Angelicae Sinensis Radix-free group. Latent time, writhing times, inhibition rate, prostaglandin F_2_α(PGF_2_α) and prostaglandin E_2(PGE_2) levels in serum, endothelin-1, Ca~(2+), expression levels of prostaglandin synthase 2 G/H(PTGS2), estrogen receptor(ESR1), glucocorticoid receptor gene(NR3 C1) mRNA and protein expression levels in the uterus homogenate and pathological changes of uterine tissue were index to explore the prescription compatibility connotation and verify the mechanism of SWD in the treatment of PD. Compared with the extraction liquid of the whole recipe, the effect of Rehmanniae Radix Praeparata-free group and Paeoniae Radix Alba-free group with volatile oil were slightly lower, the effect of essential oil-free group was significantly lower, and the effect of Chuanxiong Rhizoma and Angelicae Sinensis Radix-free group was worse than that of the whole recipe. The relative expression levels of PTGS2 protein and mRNA were significantly reduced by the SWD. The relative expressions of protein and mRNA of ESR1, NR3 C1 were significantly increased. SWD treats PD by regulating the expression of key proteins PTGS2, ESR1 and NR3 C1.Its main medicinal herbs were Angelicae Sinensis Radix and Chuanxiong Rhizoma. Active components were mainly in volatile oil, but Paeo-niae Radix Alba and Rehmanniae Radix Praeparata also had some contributions.

ABSTRACT

Stilbenes is a class of natural polyphenols with 1,2-diphenylethylene as the skeleton structure which have structural and active diversity. However, there are fewer studies on their metabolic process, which limits the in-depth research and development of such components. An UPLC-MS/MS method simultaneously determining contents of ten stilbenes was firstly established in this study and applied to study the ten stilbenes of peony seed coats in the serum of C57 mice.Piceatannol was the internal standard, and methanol was used for protein precipitation, UPLC-MS/MS with negative ion mode was used for analysis, and the method was validated.The serum samples were collected and detected after mice being oral administered with 800 mg·kg~(-1) peony seed coat extracts for 8 weeks. The results showed that suffruticosol A, suffruticosol B, suffruticosol C, trans-ε-viniferin, cis-gnetin H, trans-suffruticosol D and trans-gnetin H were detected in serum samples, and the highest is suffruticosol A. The method is simple and quick with high specificity and sensitivity, and it is suitable for quantitative determination of ten stilbenes in the serum of mice.

ABSTRACT

The powder X-ray diffraction(PXRD) technique was used to investigate fourteen kinds of Ranunculaceae herbal decoction pieces(RHDP) recorded in Chinese Pharmacopoeia and to explore a novel PXRD quality control method for RHDP. The results indicated that only three RHDP-Paeoniae Radix Alba, Paeoniae Radix Rubra, and Moutan Cortex, contained calcium oxalate monodydrate(COM), whereas no COM existed in other eleven kinds of RHDP. The difference in PXRD for Paeoniae Radix Alba and Paeoniae Radix Rubra from different growing areas were investigated. The quantitative analysis method for COM was discussed by considering the water-boiling manufacturing process of herbal decoction pieces. The water-boiling experiments revealed that the PXRD peaks from COM crystals in RHDP were enhanced significantly after boiling. Paeoniae Radix Alba, Paeoniae Radix Rubra, Moutan Cortex, Aconiti Lateralis Radix Praeparata, Aconiti Radix, Aconiti Kusnezoffii Radix, and Anemone Raddeanae Rhizoma exhibited a similar series of broader peaks in the 2θ region of 15° to 35°, whose origins were discussed on the basis of chemical constituents RHDP reported by other researchers. These diffraction broader peaks most likely originated from periodic orientation of benzene ring in organic molecular crystals of aconitine-and paeonolum-based alkaloids and glycosides chemical constituents, subsequently, possibly from some other organic constituents. The PXRD technique can be used to rapidly identify Cimicifuga heracleifolia with an amorphous dispersion peak and C. dahurica with a sharp-peak feature. Climatidis Radix et Rhizoma exhibited a series of sharp PXRD peaks. The PXRD method can provide a valuable quality control method for RHDP.

ABSTRACT

This study aims to compare the differences of Paeonia lactiflora from different habitats by establishing fingerprint. The fingerprint of P. lactiflora was established by UPLC. The samples collected from Sichuan,Hebei,Henan,Shanxi and Anhui were analyzed. The common peaks were identified by UPLC-Q-TOF/MS. The relative peak area of the common peaks was analyzed through similarity evaluation system( 2012 edition) for chromatographic fingerprint of traditional Chinese medicine developed by the National Pharmacopoeia Commission. Twelve common peaks were obtained and ten components were identified by reference substance and literature comparison. The similarity of each sample to the reference fingerprint is greater than 0. 900. However,all samples were clearly divided into 5 groups according to habitats after PLS-DA analysis. The peaks 2,6( ethyl gallate),10( galloypaeoniflorin) and 12( benzoyl paeoniflorin) were found to be the main difference components between the samples from five different habitats through the VIP value map. The study found that the variety of ingredients in the different areas are basically similar. But there are some differences in the content of the four components. The results of this study can provide reference at choosing and utilizing P. lactiflora from different places comprehensively.

ABSTRACT

To further investigate the metabolism of Tripterygium wilfordii and Paeonia lactiflora micro-emulsion gel in vivo,an LCMS/MS method was established for the determination of triptolide and paeoniflorin in T. wilfordii and P. lactiflora micro-emulsion gel.The extracorporeal recovery rate of blood probe was measured by concentration difference methods( incremental method and decremental method). Meanwhile,the skin and blood micro-dialysis methods of tripterine and paeoniflorin were established,and the pharmacokinetics of T. wilfordii microemulsion gel in skin and blood was studied by micro-dialysis combined with LC-MS/MS quantitative analysis. The results showed that the established method for the determination of triptolide and paeoniflorin in T. wilfordii microemulsion gel was well linear within the required range,and the specificity,recovery rate and degree of precision of the chromatography all conformed to the research requirements of micro-dialysis samples. The stability of freeze-thawing and the residual effect all conformed to the criteria of biological sample methodology. The probe recovery rates measured by incremental method and decremental method were almost consistent with the extracorporeal recovery rate test. The recovery rates of paeoniflorin in skin and blood micro-dialysis were( 30. 60±1. 09) % and( 28. 01± 1. 75) %,respectively. And the recovery rates of skin and blood micro-dialysis were( 26. 79 ± 2. 78) % and( 25. 39±1. 86) %,respectively. The intraday recovery rate of probes was stable within 11 h. The results of pharmacokinetic study showed that the Cmaxvalues of triptolide in skin and blood were( 148. 03±41. 51) and( 76. 77±15. 27) μg·L-1,respectively. And the Tmaxvalues were( 2. 33±0. 29) and( 3. 00± 0) h,respectively. The AUC0-11 hvalues were( 2 814. 05± 1 070. 37) and( 1 580. 63±208. 27) μg·h·L-1,respectively. The MRT0-11 hvalues were( 4. 20± 0. 33) and( 4. 54± 0. 34) h,respectively. The T1/2 values were( 4. 61±4. 11) and( 1. 07± 0. 13) h,respectively. The Cmaxvalues of paeoniflorin in skin and blood were( 991. 88 ± 152. 22) and( 407. 02±120. 06) μg·L-1,respectively. The Tmaxvalues were( 2. 00±0) h and( 2. 83±0. 29) h,respectively. The AUC0-11 hvalues were( 18 430. 27±3 289. 35) and( 6 338. 59 ± 1 659. 32) μg·h·L-1,respectively. The MRT0-11 hvalues were( 4. 29 ± 0. 16) and( 4. 00±0. 05) h,respectively. The T1/2 values were( 2. 16±0. 43) and( 1. 78±0. 48) h,respectively. The results suggested that micro-emulsion gel played a role in forming skin reservoir through percutaneous penetration. It not only could improve drug transdermal efficiency,but also control the sustained release of drug and form a long-term effect.

ABSTRACT

Guizhi Decoction is a resolving agent,which is a classic prescription for traditional Chinese medicine. It is effective in the treatment of sepsis in clinical practice. However,due to the complexity of the prescription,its anti-sepsis mechanism is difficult to be clarified. The " Cinnamomi Ramulus-Paeoniae Radix Alba" drug pair,as the classic compatibility for medicinal and medicinal herbs,is the core of Guizhi Decoction. In this study,Cinnamomi Ramulus-Paeoniae Radix Alba drug pair was used as the research object and the molecular mechanism of its treatment of sepsis was investigated by analyzing the chemical compositions with integrative pharmacology platform( TCMIP,http://www.tcmip.cn/),predicting disease target,analyzing gene function and pathway of " Cinnamomi Ramulus-Paeoniae Radix Alba" in treatment of sepsis,and establishing a multi-dimensional network relationship of " Chinese medicine-chemical components-core targets-key pathways". The prediction results of " Cinnamomi Ramulus-Paeoniae Radix Alba" drug pair showed that its anti-sepsis effect was associated with 45 active components,and the active components played an anti-sepsis role through multiple targets and pathways,involving inflammatory targets such as PF4,MyD88,TLR4,BDKRB2,CD14,and NOS3. The sepsis was relieved mainly by regulating Toll like signaling pathway,Fox O signaling pathway,chemokines signaling pathway,thyroid and insulin endocrine signaling pathways and biological processes. This study provides a scientific basis for further development of Cinnamomi Ramulus-Paeoniae Radix Alba drug pair and Guizhi Decoction against sepsis.

ABSTRACT

The traditionally used oriental herbal medicine Moutan Cortex Radicis [MCR; Paeonia Suffruticosa Andrews (Paeoniaceae)] exerts anti-inflammatory, anti-spasmodic, and analgesic effects. In the present study, we investigated the therapeutic effects of differently fractioned MCR extracts in a 6-hydroxydopamine (OHDA)-induced Parkinson's disease model and neuro-blastoma B65 cells. Ethanol-extracted MCR was fractionated by n-hexane, butanol, and distilled water. Adult Sprague-Dawley rats were treated first with 20 μg of 6-OHDA, followed by three MCR extract fractions (100 or 200 mg·kg) for 14 consecutive days. In the behavioral rotation experiment, the MCR extract-treated groups showed significantly decreased number of net turns compared with the 6-OHDA control group. The three fractions also significantly inhibited the reduction in tyrosine hydroxylase-positive cells in the substantia nigra pars compacta following 6-OHDA neurotoxicity. Western blotting analysis revealed significantly reduced tyrosine hydroxylase expression in the substantia nigra pars compacta in the 6-OHDA-treated group, which was significantly inhibited by the n-hexane or distilled water fractions of MCR. B65 cells were exposed to the extract fractions for 24 h prior to addition of 6-OHDA for 30 min; treatment with n-hexane or distilled water fractions of MCR reduced apoptotic cell death induced by 6-OHDA neurotoxicity and inhibited nitric oxide production and neuronal nitric oxide synthase expression. These results showed that n-hexane- and distilled water-fractioned MCR extracts inhibited 6-OHDA-induced neurotoxicity by suppressing nitric oxide production and neuronal nitric oxide synthase activity, suggesting that MCR extracts could serve as a novel candidate treatment for the patients with Parkinson's disease.

ABSTRACT

The traditionally used oriental herbal medicine Moutan Cortex Radicis [MCR; Paeonia Suffruticosa Andrews (Paeoniaceae)] exerts anti-inflammatory, anti-spasmodic, and analgesic effects. In the present study, we investigated the therapeutic effects of differently fractioned MCR extracts in a 6-hydroxydopamine (OHDA)-induced Parkinson's disease model and neuro-blastoma B65 cells. Ethanol-extracted MCR was fractionated by n-hexane, butanol, and distilled water. Adult Sprague-Dawley rats were treated first with 20 μg of 6-OHDA, followed by three MCR extract fractions (100 or 200 mg·kg) for 14 consecutive days. In the behavioral rotation experiment, the MCR extract-treated groups showed significantly decreased number of net turns compared with the 6-OHDA control group. The three fractions also significantly inhibited the reduction in tyrosine hydroxylase-positive cells in the substantia nigra pars compacta following 6-OHDA neurotoxicity. Western blotting analysis revealed significantly reduced tyrosine hydroxylase expression in the substantia nigra pars compacta in the 6-OHDA-treated group, which was significantly inhibited by the n-hexane or distilled water fractions of MCR. B65 cells were exposed to the extract fractions for 24 h prior to addition of 6-OHDA for 30 min; treatment with n-hexane or distilled water fractions of MCR reduced apoptotic cell death induced by 6-OHDA neurotoxicity and inhibited nitric oxide production and neuronal nitric oxide synthase expression. These results showed that n-hexane- and distilled water-fractioned MCR extracts inhibited 6-OHDA-induced neurotoxicity by suppressing nitric oxide production and neuronal nitric oxide synthase activity, suggesting that MCR extracts could serve as a novel candidate treatment for the patients with Parkinson's disease.
