ABSTRACT

The current study aims to rapidly and comprehensively profile the chemical composition of Cistanche salsa using direct infusion coupled with MS/MS~(ALL)(DI-MS/MS~(ALL)). The C. salsa extract was directly imported into electrospray ionization(ESI) source of quadrupole time-of-flight(Q-TOF) mass spectrometer with an infusion pump at a flow rate of 10 μL·min~(-1). Acquisition program was applied under negative ionization polarity to collect one MS~1 spectrum(m/z 50-1 200), followed by 1 150 MS~2 spectra with precursor isolation window(m/z 1) amongst mass range m/z 50-1 200. After each MS~2 spectrum was matched to its precursor ion, putative identification was conducted through matching mass spectral data with literature and database. A total of 31 components were identified from C. salsa, including 9 phenylethanoid glycosides, 2 iridoids, 4 saccharides, 9 organic acids, and 7 other compounds, similar to those from C. tubulosa and C. deserticola. In conclusion, DI-MS/MS~(ALL), a facile and reliable analytical tool, can be employed for qualitative analysis of chemical constituents in C. salsa. The research offers a promising strategy to achieve rapid chemome profiling of herbal medicine and provides an alternative source of Cistanches Herba.

ABSTRACT

Several Orobanche medicinal plants sometimes served as alternative sources of Cistanches Herba, attributing to the benefits such as tonifying kidney, strengthening tendons and bones. Among them, O. coerulescens, O. cernua and O. pycnostachya have been widely utilized in northern China for treatments of pains in the loins and knees, impotence, and spermatorrhea. However, their chemical profiles haven't been elucidated. In the present study, UHPLC-IT-TOF-MS was implemented to conduct in-depth chemome profiling of O. coerulescens, O. cernua and O. pycnostachya, aiming to achieve a comprehensive chemical characterization and to provide pronounced information for the quality control and clinical applications. An ACE Ultra-Core 2.5 Super C_(18)(3.0 mm×150 mm, 2.5 μm) column was deployed for chromatographic separations, and high-resolution MS~n spectra were recorded by IT-TOF-MS. Forty-eight components, in total, were observed, and thirty-eight ones were structurally annotated according to proposing mass fragmentation patterns, matching with relevant databases. Particularly, nine ones were confirmed by reference compounds. Overall, the chemical compositions of O. coerulescens and O. cernua are quite similar, and differences occur between O. pycnostachya and the prior two ones; primary chemical family is phenylethanoid glycosides, and several lignan glycosides as well as iridoid glycosides are also observed; the primary components include acteoside, isoacteoside, crenatoside and 2'-acetylacteoside, etc.

ABSTRACT

In this study, taking Cistanche deserticola in Xinjiang as the experimental material, the optimal process for extracting polysaccharides from C. deserticola with water extraction was studied by using single factor and orthogonal experiment. Its effects on protein removal and polysaccharides retaining were investigated by using Sevag, enzymatic method or combination of these two methods, so as to determine the optimal method for protein removal from polysaccharides of C. deserticola; the decolorization and purification methods such as macroporous resin of AB-8 and activated Carbon were used to determine the optimal process. The results showed that the extraction rate of polysaccharides from C. deserticola was 18.40% during the optimal process of the water extraction as follows: extraction temperature 75 ℃, extraction time 165 min and solid-liquid ratio 1∶55. The protein removal rate can reach 31.40% and polysaccharide retention rate can reach 96.00% under the optimal protein removal process: temperature 50 ℃, time 2 h, and papain dosage 0.2%. The decolorization rate of activated Carbon and macroporous resin called AB-8 was 80.37% and 86.43%, and the recovery rate of polysaccharides was 77.05% and 91.93%, respectively, suggesting that macroporous resin was more suitable for decoloration. Macroporous resin named AB-8 increased the purity of the polysaccharide crude extract from 67.70% to 84.80% under the following conditions: concentration of the sample 4 g·L~(-1), concentration of the eluent 60% ethanol, and the flow rate 1 mL·min~(-1), showing significant purification effect.

ABSTRACT

To investigate the inhibitory effects and mechanism of Cistanche tubulosa ethanol extract( CTEE) against oxygen-glucose deprivation/reperfusion( OGD/R)-induced PC12 cells neuronal injury. In this study,OGD/R-induced PC12 cells were used to explore the neuroprotective effects of CTEE( 12. 5,25,50 mg·L-1) by detecting cell viability with MTT assay,apoptosis with AO/EB and Hoechst 33258,mitochondrial membrane potential changes with JC-1 staining,mitochondrial oxidative stress with MitoSOX staining,as well as the apoptosis-related protein expression( PARP,cleaved PARP,caspase-3,cleaved caspase-3,Bax,Bcl-2) with Western blot. RESULTS:: showed that CTEE effectively protected OGD/R-induced neuronal injury and increased the survival rate of PC12 cells.AO/EB and Hoechst 33258 staining showed that CTEE could effectively inhibit apoptosis. Moreover,JC-1 and MitoSOX staining results showed that CTEE decreased mitochondrial stress and mitochondrial membrane potential imbalance in PC12 cells in a concentration-dependent manner. Meanwhile,CTEE could obviously suppress the activation of key proteins in mitochondrial apoptosis pathway such as caspase-3 and PARP,and significantly inhibit the rise of Bax and down-regulation of Bcl-2. In conclusion,CTEE has obvious protective effects on OGD/R-induced PC12 cells neuronal injury,potentially via inhibiting mitochondrial oxidative stress and apoptosis-related signaling pathway.

ABSTRACT

To intuitively understand the phenotypic diversity of intra-population and inter-population of the medicinal Cistanche Herba distributed in Xinjiang province, three species of Cistanche Herba were selected for the first time to be conducted to phenotypic observation and measurement from the morphological perspective, aiming to fill the gap in the morphological research concerning Cistanche Herba, and discuss about the relationship between the phenotypic variation and the host plants together with the geographical conditions, thus better understanding the speciation and evolutionary mechanism of Cistanche Herba and providing some scientific basis for the resource protection and germplasm breeding of Cistanche Herba. Based on sampling survey, a total of 118 well grown medicinal Cistanche samples from 17 Cistanche Herba distribution areas in Xinjiang province were selected, and various indexes were observed and measured. Besides, ANOVA and clustering analysis were conducted with 9 phenotypic quantity characters. The Cistanche Herba was plentiful in phenotypic variation. For detail, significant intra-population differences were observed in eight of the nine character indexes, and the intra-population differences were more obvious than those of inter-population. For each quantity character of the three species, the flower density possessed the maximal variable coefficient (71.1%) while the flower length was the minimum (15.9%). The phenotypic variation was also obvious among different populations. Specifically, the average variable coefficient of flower number was the maximal one (46.5%) and the flower length was the minimum one (10.0%). For different populations, the average variable coefficient of the D4 population was the maximal one (41.1%) and the S3 population was the minimum one (13.5%). According to the clustering analysis, all the samples of Cistanche Herba could be divided into three groups when the Euclidean distance was set at 15. The populations of S1, S3, D1, S2, D4, D6, D7 and D5 which distributed in the north of Xinjiang were clustered into one group, and the populations of D8, S4, D9, D2 and D3 that grown in east and central of Xinjiang were clustered into another group. The populations of C. deserticola and C. salsa could not be completely separated, but both of them were obviously differentiated from the T1, T3 and T2 populations of C. tubulosa. Besides, the C. deserticola and C. salsa displayed a patch distribution among different populations, and similar phenotypic characters were shared for each population. The research results of phenotype were consistent with that of molecular biology study of Cistanche Herba. The different phenotypic characters in different distribution areas were deduced to be arose from geographical isolation caused by mountains, which led to the specific genetic structure for each population of Cistanche Herba during the long-term adaptation and evolution. In conclusion, the current study showed the adaptation potency of Cistanche Herba exposed to different habitats.

ABSTRACT

The genus Orobanche, Cistanche and Boschniakia are taxonomically classified as members of Orobanchaceae. The medicinal plants of these three genera are closely related, and their traditional curative effects are similar. As representative compounds, phenethyl glycosides are predominantly dominant type both in amount and in chemical structural varieties, which are considered to be the important bioactive material basis of these genera. In this paper, phenethyl glycosides and their pharmacological activities are described in a single list. In addition, the other compounds were also reviewed in order to better compare the difference of the bioactive substances. These findings have important reference value for effective development and rational utilization of resources of medicinal plants in the family Orobanchaceae.

ABSTRACT

Echinacoside, an active compound in the herb Herba Cistanche, has been reported to inhibit glutamate release. In this study, we investigated the effects of echinacoside on spontaneous excitatory synaptic transmission changes induced by 4-aminopyridine (4-AP), by using the in vitro rat hippocampal slice technique and whole-cell patch clamp recordings from CA3 pyramidal neurons. Perfusion with echinacoside significantly suppressed the 4-AP-induced epileptiform activity in a concentration-dependent manner. Echinacoside reduced 4-AP-induced increase in frequency of spontaneous excitatory postsynaptic currents (sEPSCs) but it did not affect the amplitude of sEPSCs or glutamate-activated currents, implicating a presynaptic mechanism of action. Echinacoside also potently blocked sustained repetitive firing, which is a basic mechanism of antiepileptic drugs. These results suggest that echinacoside exerts an antiepileptic effect on hippocampal CA3 pyramidal neurons by simultaneously decreasing glutamate release and blocking abnormal firing synchronization. Accordingly, our study provides experimental evidence that echinacoside may represent an effective pharmacological agent for treating epilepsy.

ABSTRACT

In order to determine the chemical constituents of Cistanche deserticola cultured in Tarim desert, a systematically phytochemical investigation was carried out. The constituents were isolated by silica gel, Sephadex LH-20, MCI gel, ODS column chromatography, and semi-preparative HPLC. Their structures were determined on the basis of MS and NMR spectroscopic analyses, by chemical methods, and/or comparison with literature data. The anti-inflammatory activities of the isolates were evaluated for their inhibitory effects on the lipopolysaccharide (LPS)-induced nitric oxide (NO) production in BV-2 mouse microglial cells. Nine iridoids were isolated and identified as cistadesertoside A (1), cistanin (2), cistachlorin (3), 6-deoxycatalpol (4), gluroside (5), kankanoside A (6), ajugol (7), bartsioside (8), and 8-epi-loganic acid (9). Compound 9 exhibited potent inhibition on the NO production with an IC50 value being 5.2 μmol·L(-1), comparable to the positive control quercetin (4.3 μmol·L(-1)). Compound 1 was a new iridoid, and compounds 5, 6, and 8 were isolated from this species for the first time.

ABSTRACT

At present, the objective of cutting and pruning Cistanche deserticola is to harvest in successive years and enhance the harvesting yield and quality of C. deserticola in the process of the artificial cultivating C. deserticola. An experiment was conducted focusing on cutting and pruning C. deserticola in artificial forests of Haloxylon ammodendron drip-irrigated with saline water at the hinter-land of the Taklimakan desert, according to different growth stages and lengths. The results were following: (1) The effect of cutting on C. deserticola was similar to that of pruning, which resulted in three kinds of morphological types, not related to the bloom and size of C. deserticola. (2) The growth forms were diversified after pruning. Among them, there had sprouting new body, died or maintaining life with no sprouting, mildewed on its surface layer, etc. However, some of new bodies were sprouting from the lower part of the old body. The death rate of bloomed C. deserticola was higher than that of the underground, and the death rate of the 40 cm in stubble height for C. deserticola was higher than those with the stubble height of 20 cm and 5 cm. (3) Most of the diameter of living C. deserticola after pruning was increasing, but some of them changed little. (4) The mildew and rot of C. deserticola and the broken of the roots of the H. ammodendron and the fallen of the point of the inoculated when it was dug, which would cause the death of the C. deserticola. On the other, the yield-increasing effect and the economic benefit of the techniques of the pruning of Cistanche would need further research and evaluate. Therefore, the application of this technique needs to be cautious.

ABSTRACT

Since scalp hair loss has increased recently even in young people, seriously affecting individual's quality of life, the hair growth-stimulating effects of Laminaria japonica extract (LJE) and Cistanche tubulosa extract (CTE) were investigated. After confirming anagen phase of follicles under shaving, male C57BL/6 mice were dermally applied with 3% Minoxidil or orally administered with the combinations of LJE and CTE for 21 days. Minoxidil promoted the hair regrowth and increased gamma-glutamyl transpeptidase (gamma-GTP) and alkaline phosphatase (ALP) activities. In addition, Minoxidil up-regulated epidermal growth factor (EGF) and vascular endothelial growth factor (VEGF) levels. Co-administration of LJE and CTE at 54 mg/kg LJE plus 162 mg/kg CTE exerted synergistic promoting effects on the hair regrowth, comparable to 3% Minoxidil. LJE preferentially enhanced ALP activity, while CTE increased both gamma-GTP and ALP activities as well as EGF and VEGF expressions. In vivo air pouch inflammation model, carrageenan-induced vascular exudation and increased nitric oxide and prostaglandin E2 concentrations in the exudates were synergistically suppressed by co-administration of LJE and CTE. In addition, inflammatory cell infiltration was substantially inhibited by the combinational treatment. The results suggest that combinational oral treatment with LJE and CTE in appropriate doses and ratios prevent hair loss and improve alopecia, which might be in part mediated by their anti-inflammatory activities.

ABSTRACT

Cistanche tubulosa and Laminaria japonica have been reported to have anti-oxidative, anticoagulant, anti-cancer and anti-inflammatory properties. They are expected to be a promising candidates for promoting hair growth and treating dandruff and scalp inflammation as a consequence. In this double-blinded, placebo-controlled clinical trial, we investigated the efficacy of Cistanche tubulosa extract and Laminaria japonica extract complex (MK-R7) in promoting hair health in patients with mild to moderate patterned hair loss. Using phototrichogram (Folliscope 4.0, LeadM, Seoul, Korea), we compared the density and diameter of hairs in patients receiving a placebo or Cistanche tubulosa extract and Laminaria japonica extract complex (MK-R7) at baseline, 8 and 16 weeks of the study. In order to determine the efficacy of treatment on dandruff and scalp inflammation, investigator's assessment score and patient's subjective score were also performed. We found a statistically significant increase in the hair density of the test group (n = 45, MK-R7 400 mg) after 16 weeks of consuming the MK-R7 (test group: 23.29 n/cm2 +/- 24.26, control: 10.35 n/cm2 +/- 20.08, p < 0.05). In addition, we found a statistically significant increase in hair diameter in the test group compared to control group at week 16 (test group: 0.018 mm +/- 0.015, control: 0.003 mm +/- 0.013, p < 0.05). There were also significant outcomes regarding the investigator's visual assessment and patient's subjective score of dandruff and scalp inflammation in the test group compared to those in control group. Based on the results of this clinical study, we conclude that Cistanche tubulosa extract and Laminaria japonica extract complex (MK-R7) are promising substances for promoting health of the scalp and hair.

ABSTRACT

<p><b>OBJECTIVE</b>To explore the abnormal expressions of testicular reproduction-related genes induced by glycosides of Tripterygium wilfordii (GTW) and the intervention with kidney-tonifying Chinese herbs.</p><p><b>METHODS</b>Adult Balb/C male mice were fed on GTW at 30 mg per kg per d for 3 weeks to establish a model of reproductive dysfunction. The model mice were divided into different groups to receive intragastrical administration of saline (0.25 ml/d), GTW (30 mg per kg per d), Cistanche (10 g per kg per d), Rehmannia (10 g per kg per d), and Rehmannia + Cistanche (20 g per kg per d), respectively, once a day for 3 weeks. And a Cistanches pretreatment group was treated with GTW (30 mg per kg per d) and Cistanche (10 g per kg per d) for the same length of time. Then we detected the changed expressions of testicular reproduction-related genes Dzip1, Fas, c-jun and Wnt4 in each group.</p><p><b>RESULTS</b>The model mice showed an obviously down-regulated expression of the Y chromosome microdeletion-related gene Dzip1, and up-regulated expressions of the germ cell apoptosis-related gene Fas, proto-oncogene c-jun, and signal transduction-related gene Wnt4. Intervention with Chinese herbs achieved different degrees of improvement of the mice's reproductivity, and the most obvious efficacy was observed with the combined use of kidney-yang tonifying Cistanche and kidney-yin nourishing Rehmannia.</p><p><b>CONCLUSION</b>GTW exerts significant impact on reproduction-related genes. Both the kidney-yang tonifying drug Cistanche and kidney-yin nourishing drug Rehmannia can counteract some of the reproductive toxicity of GTW, while the combination of the two can further enhance the effect.</p>
