ABSTRACT
To clarify the content characteristics of the main active components and mineral elements of Cynomorium songaricum under different habitat conditions, and further explore the relationship between the quality of C. songaricum and habitats, this study took C. songaricum from 25 different habitats in China as the research object, and measured the contents of 8 main active components and 12 mineral elements separately. Diversity analysis, correlation analysis, principal component analysis and cluster analysis were carried out. The results showed that the genetic diversity of total flavonoids, ursolic acid, ether extract, potassium(K), phosphorus(P) and zinc(Zn) in C. songaricum was high. The coefficient of variation of crude polysaccharide, ether extract, gallic acid, protocatechuic aldehyde, catechin, epicatechin, calcium(Ca), sodium(Na), magnesium(Mg), sulfur(S), iron(Fe), manganese(Mn), selenium(Se) and nickel(Ni) were all over 36%, indicating that the quality of C. songaricum was significantly affected by habitats. There were strong synergistic and weak antagonistic effects among the contents of the 8 active components, and complex antagonistic and synergistic effects among the contents of the 12 mineral elements. Principal component analysis revealed that crude polysaccharide, ursolic acid, catechin, epicatechin and total flavonoids could be used as the characteristic components to evaluate the quality of C. songaricum, and Na, copper(Cu), Mn and Ni were the characteristic elements to evaluate the quality of C. songaricum. In cluster ana-lysis, the second group with the main active components as cluster center had better quality in terms of the content of active substances, and the second group with the mineral elements as cluster center had higher utilization potential in the exploitation of mineral elements. This study could provide a basis for resource evaluation and breeding of excellent varieties of C. songaricum in different habitats, and provide a reference for cultivation and identification of C. songaricum.

A quantitative analysis of multi-components by single marker method (QAMS) was established for simultaneous determination of gallic acid, protocatechuic acid, catechin, epicatechin, p-coumaric acid, ferulic acid and phloridzin in Cynomorium songaricum Rupr. The analysis was performed on a ChromCore Polae C18 column (250 mm×4.6 mm, 5 μm) , with a mobile phase consisting of acetonitrile-0.3% phosphoric acid aqueous solution for gradient elution. The volume flow rate, column temperature and sample injection volume were set at 1.0 mL·min-1, 25 ℃, and 40 µL, respectively. The relative correction factors of gallic acid and protocatechuic acid, catechin, epicatechin, p-coumaric acid, ferulic acid and phloridzin were calculated and the durability was also investigated. The contents of these seven compounds in fourteen batches of Cynomorium songaricum Rupr. from different producing areas or batches were determined by external standard method (ESM) and quantitative analysis of multi-components with a single-marker method (QAMS), respectively. SPSS and Origin Pro software were employed for principal components assay, similarity evaluation and cluster analysis. The specificity, precision, repeatability, stability and linear range (R2 > 0.999 0) of the seven components were all good. The average recovery was 96.89%-103.16% and RSD was 0.55%-2.76%. Then gallic acid was chosen as internal reference for calculation the correction factors for the other six components, the average relative correction factors of protocatechuic acid, catechin, epicatechin, p-coumaric acid, ferulic acid and phloridzin were 1.141 5, 0.200 5, 0.208 0, 2.361 9, 1.867 7, 0.204 6, respectively. Student's test results showed that there was no significant difference between the data analyzed by ESM and the data obtained from QAMS method. Through data visualization analysis, the contents of gallic acid, protocatechuic acid, catechin and epicatechin in different samples were significantly different, indicating that these four components might be the main quality markers of Cynomorium songaricum Rupr. for gaving more contributes to the principal components. The cluster analysis showed that samples from Xinjiang and samples from Inner Mongolia were clustered in significantly different categories, meaning that the quality of Cynomorium songaricum Rupr. had great relation with producing areas. The method of QAMS established in this study is a simple, economical and practical method with scientific and applicable charactistics for evaluating the quality of Cynomorium songaricum Rupr. efficiently and scientifically.
ABSTRACT
To explore the characteristics of soil microbial communities of Cistanche deserticola and Cynomorium songaricum, two typical parasitic medicinal plants that live in an extreme saline alkali environment, 16S PCR was used to sequence the soil microbial communities of C. deserticola and C. songaricum in Ebinur Lake, Xinjiang. Redundancy analysis and correlation analysis were carried out based on the abundance of core microbiome and ecoclimatic factors. The results show that the diversity of the soil microbial community of C. deserticola was significantly higher than that of C. songaricum. The core microbial groups of C. deserticola and C. songaricum were Marinomona, Halomonadaceae, Rhizobiales, Halomonas, and Acidimicrobiales. Six specific biomarkers were identified as Micrococcacea, Echinicola, Glutamicibacter, Galbibacter, Pseudoalteromonas, and Marinobacterium_ rhizophilum. The results of redundancy analysis and correlation analysis show that the average temperature in the driest season and the average temperature in the coldest season, and the clay content and soil texture classification were the main ecological factors affecting the composition of these soil microbial communities. This study provides a theoretical basis for finding molecular markers of C. deserticola and C. songaricum and promoting the quality of C. deserticola and C. songaricum.
ABSTRACT
Objective: To identify and comprehensively evaluate Cynomorium songaricum from different producing areas in order to provide reference for the quality evaluation of C. songaricum and the determination of the suitability of the origin. Methods: A total of 40 samples from five provinces (regions) were collected to measure the content of gallic acid, protocatechuic acid, catechins, total polysaccharides, total flavonoids, Na, K, Ca, Mg, Fe, Zn, Mn, Co, Sr, Ni, Ag, Ba, Ti, Cu, Pb, Cr, Cd, As, and Hg. The data reflecting the quality of C. songaricum were analyzed by orthogonal partial least squares discriminant analysis (OPLS-DA) and entropy weight TOPSIS analysis. Results: The contents of Mn, Zn, Co, catechin, Pb, Cr, Ca, Ti, total flavonoids, protocatechuic acid, Mg and Cu in C. songaricum are important for distinguishing different producing areas. The quality of C. songaricum in Inner Mongolia was the best in all provinces (regions), followed by Gansu, Ningxia, Xinjiang, and Qinghai Provinces. Conclusion: The results of OPLS-DA combined with entropy weight TOPSIS analysis are reasonable, objective and effective, and can be applied to the comprehensive evaluation of multiple indicators of C. songaricum.
ABSTRACT
<p><b>Objective</b>To investigate the effects of cynomorium songaricum (CS) decoction on the testis weight, serum testosterone level, and sperm parameters of rats with oligoasthenospermia (OAS), explore its action mechanism of improving the proliferation of undifferentiated spermatogonial cells, and provide some experimental and theoretical evidence for the development of new Chinese drugs for OAS.</p><p><b>METHODS</b>Thirty 8-week-old male SD rats were randomly divided into five groups of equal number: blank control, model control, high-dose CS, medium-dose CS, and low-dose CS. OAS models were established by intraperitoneal injection of cyclophosphamide and, a month later, treated intragastrically with normal saline or CS at 2, 1, and 0.5 g per kg of the body weight per day, all for 4 weeks. Then, the testes of the animals were harvested to obtain the testicular weight, sperm concentration and motility, and the level of serum testosterone (T), detect the expressions of the transcription factor 1 (Oct4), Thy-1 cell surface antigen (Thy1), promyelocytic leukemia zinc finger (PLZF), KIT proto-oncogene receptor tyrosine kinase (C-kit) and glial cell-derived neurotrophic factor (GDNF) in the testis tissue of the rats in the low-dose CS group by real-time PCR.</p><p><b>RESULTS</b>The testis weights in the blank control, model control, high-dose CS, medium-dose CS, and low-dose CS groups were (1.52±0.06), (1.55±0.06), (1.43±0.30), (1.35±0.40) and (1.34±0.04) g, respectively, not significantly different in the blank and model controls from those in the CS groups (P>0.05). The visual field sperm count per 10 HP was significantly increased in the high-, medium-, and low-dose CS groups (202±20, 196±5 and 216±25) as compared with the blank and model controls (200±15 and 134±30) (P<0.05). The mRNA expressions of the Oct4, Thy1, PLZF and GDNF genes were remarkably higher in the low-dose CS group than in the controls (P<0.05), but that of the C-kit gene showed no significant difference from the latter (P>0.05). The visual field sperm motility per 10 HP was markedly increased in the blank control (［52.1±5.5］%), model control (［38.1±2.5］%), high-dose CS (［59.1±9.5］%), medium-dose CS (［58.7±9.5］%), and low-dose CS (［49.6±1.0］%) groups, and so was the level of serum testosterone (［190±87.5］, ［82.5±25.8］, ［229±75.6］, ［331±86.7］ and ［185±82.4］ mmol/L), both remarkably higher in the CS groups than in the model controls (P<0.05) but with no statistically significant difference between the CS groups and the blank controls (P>0.05).</p><p><b>CONCLUSIONS</b>CS can significantly improve sperm concentration, sperm motility and serum T level in OAS rats, probably by inducing the expression of GDNF in the rat Sertoli cells, promoting the proliferation of undifferentiated spermatogonial cells, and enhancing spermatogenesis.</p>
ABSTRACT
To study the effect of Cynomorium songaricum polysaccharide (CSRP) on A549 cells telomere of human non-small cell lung cancer, the mice were intragastric administrated with CSRP (0.08 g•kg⁻¹) once daily for 4 days. Then their serum was taken for preparing CSRP drug serum. A549 cells were treated by the drug serum, and the effect of drug serum with different concentrations and different treating time on the proliferation of non-small cell lung cancer A549 cells was determined by MTT test. After treating for 48 hours by the drug serum of different concentrations, the telomere length of the cells was determined by fluorescence quantitative polymerase chain reaction (qPCR); the mRNA expression of telomerase reverse transcriptase (TERT) was determined by RT-qPCR; the cells apoptosis was determined by TUNEL assay. The results demonstrated that CSRP of various concentrations could inhibit the proliferation of the lung cancer A549 cells significantly, and the inhibition effect was strongest at 48 hours with the concentration of 6.0 mL•L⁻¹. At 48 h, that CSRP of the concentrations from 1.5 to 12.0 mL•L⁻¹ could significantly shorten the telomere length of A549 cells, and the effect was strongest with the concentration of 1.5 mg•L⁻¹. CSRP of various concentrations could significantly inhibit the mRNA expression of TERT in A549 cells, and the inhibition effect was stronger when the concentration was ≥6.0 mL•L⁻¹. CSRP of various concentrations could promote A549 cells apoptosis, and the effect was stronger when the concentration was ≥6.0 mL•L⁻¹. In conclusion, CSRP has the anti-cancer effect, and the action mechanism may be associated with inhibiting TERT mRNA expression, shortening telomere length, inhibiting cells proliferation and promoting cells apoptosis.
ABSTRACT
OBJECTIVE: To study the effect of ethyl acetate extract of Songaricum Rupron (ECS) on ovariectomization induced learning and memory disorder in rats and its potential mechanism. METHODS: SD rats were ovariectomized to establish animal model of learning and memory disorder, and taken ECS by intragastric administration(3.3 mg · kg-1). Morris water maze was used to test the learning and memory ability of rats. HE staining was used to observe morphological change of hippocampal neurons. The p38 and p-CREB expression were tested by Western-Blot. RESULTS: The latent route of OVX + ECS group in the Morris water maze was significantly shorten, while numbers of crossing platform were markedly increased, compared with OVX group. The neurological form of pyramidal cells in hippocampus were improved by HE staining. CONCLUSION: It shows that the p38 expression is reduced while p-CREB is increased in OVX + ECS group, which potentially contributes to the improvement of learning and memory disorder due to lack of endogenous estrogen.
