ABSTRACT

The present study aimed to explore the mechanism of the sweating of Dipsacus asper on content changes of triterpene sa-ponins by detecting the total triterpene saponins and the index component asperosaponin Ⅵ in the crude and sweated D. asper, and analyzing the differentially expressed proteins by isobaric tags for relative and absolute quantification(iTRAQ) combined with LC-MS/MS. After sweating, the content of total triterpene saponins decreased manifestly, while that of asperosaponin Ⅵ increased significantly. As revealed by the iTRAQ-LC-MS/MS analysis, 140 proteins with significant differential expression were figured out, with 50 up-regulated and 90 down-regulated. GO analysis indicated a variety of hydrolases, oxido-reductases, and transferases in the differential proteins. The results of activity test on two differentially expressed oxido-reductases were consistent with those of the iTRAQ-LC-MS/MS analysis. As demonstrated by the analysis of enzymes related to the triterpene saponin biosynthesis pathway, two enzymes(from CYP450 and UGT families, respectively, which are involved in the structural modification of triterpene saponins) were significantly down-regulated after sweating. The findings suggested that sweating of D. asper presumedly regulated triterpene saponins by affecting the expression of downstream CYP450 s and UGTs in the biosynthesis pathway of triterpene saponins of D. asper.

ABSTRACT

Through the records of herbal and market investigations,the samples collected from different market and origin were analyzed,and the appearance character indexes were determined in order to revise the commodity specification and grade standard of Dipsaci Radix combined with production practice. This is also to analyze association of the appearance with quality different of intrinsic components. The investigation results indicated the root's long and thick was better,and atrovirens of fracture surface,there are most of the market is dominated by the ungraded goods. Through principal component analysis,variance analysis and cluster analysis,combining with the feasibility of actual operation and herbal record,the length,middle diameter and phloem color were filtrated and the specification was divided into 2 ranks: the selection and ungraded goods,and the grade was divided into 2 ranks for the selection goods: big,small selected goods. Moreover,there were no significant correlation between the appearance and the intrinsic quality index of Dipsaci Radix,the content of extractum were significantly positive correlation with the moisture,but had extremely negative correlation with the total ash. Multiple comparisons indicated that the content of the moisture,extractum and asperosaponin VI of the selected goods were higher than the ungraded goods,while the total ash content were lower,and they hasn't significant difference. The commodity specification and grade standard of Dipsaci Radix as a basis provide commodity specification and grade standard of communities and standardizing market trade order.

ABSTRACT

In order to study the distribution and dynamics growth of wild Dipsacus asper resources in the Wulong district of Chongqing, 9 sample plots were selected for 12 consecutive months in the natural distribution area of the D. asper in Wulong district by using the sample line + plot survey method to conduct a field survey. The results showed that D.asper was distributed in forest edge wasteland or shrub-grassland, and growbetter with loose yellow-brownsoil or red soil, and poor with lithologic soil or impounded surface water.The growth curve of the plant height from June to July and the ground fresh weight from July to August showed a turning point, it might consume large amounts of nutrients during its flowering period, resulting in the restriction of vegetative growth.The highest temperature in the distribution area of D.asperoides in Wulong district is less than 30 °C, the minimum temperature is about 0 °C, and the rainfall is 1 241-1 392 mm. Its growth environment is no severecold in winter, no heat in summer, and abundant rainfall.The main growth stage of D.asper is from July to October, and the range of root dry rate was 0.162 5-0.239 7 in Xiangkou, 0.154 9-0.223 6 in Baima Mountain, and 0.143 7-0.203 3 Xiannv Mountain. The vegetative growth and dry matter accumulation synchronized in the main growth stage, and the accumulation rate of dry matter was faster than that of vegetative growth. The correlation analysis between indicators and root fresh weight showed that the fresh weight of the aerial part and root fresh weight had the best correlation.

ABSTRACT

The author detected the genetic diversity and genetic relationship within and among eight medicinal species of Dipsacus by the approach of sequence-related amplified polymorphism (SRAP). The associated genetic parameters were calculated by POPGENE 1.31. The Genetic distance was calculated by TREECONW and the systematic diagrams of genetic relationship were clustered by UPG-MA. The results showed that, using 26 primers, a total of 558 bands were produced, of which 539 were polymorphic loci. There was a high level of genetic diversity among species (PPB = 96.59%, Na = 1.9659, Na = 1.3375, H = 0.2143, I = 0.3423). However, genetic diversity was lower within species, the average of genetic parameters was PPB = 6.97%, Na = 1.0697, Na = 1.0311, H = 0.0187, I = 0.0291. The Nei's genetic differentiation coefficient was 0.9126, indicated that most of the genetic variation existed among species. By clustering analysis, different individuals gathered in the same group and the classified result of SRAP marker between traditional modal characters was almost same. The results confirmed that SRAP marker can be used as one of the effective methods to reveal the genetic diversity and relationship among medicinal species of Dipsacus.

ABSTRACT

To investigate the genetic diversity among wild Dipsacus asperoides in China, 66 germplasmic resources of D. asperoides were analyzed by Start Codon Targeted Polymorphism (SCoT) molecular markers. Genetic distance was calculated by TREECONW software and the systematic diagram of genetic relationship was clustered by UPGMA method. The results showed that the totals of 181 bands were detected using 20 primers , among which 109 were polymorphic bands. The average percentage of polymorphic bands was 60.13%. Genetic distance changed from 0.030 6 to 0.181 4. The clustering results showed that there was no significant correlation between the classification of the wild D. asperoides and their geographical origin. The relatively high genetic diversity of D. asperoides provides the basis for breeding new varieties.

ABSTRACT

In order to discriminate the crude and sweated Dipsaci Radix correctly and rapidly, the crude and sweated Dipsaci Radix were scanned by the NIR spectrometer, and an identifying model was developed by near infrared spectroscopy combined with principal component-Mahalanobis distance pattern recognition method. The pretreated spectra data of 129 crude samples and 86 sweated ones were analyzed through principal component analysis (PCA). The identifying model was developed by choosing the spectrum for 9 881.46-4 119.20 cm(-1) and "SNV + spectrum + S-G" to the original spectral preprocessing with 14 principal components, and then was verified by prediction set, identifying with 100% accuracy. The rapid identification model of the crude and sweated Dipsaci Radix by NIR is feasible and efficient, and could be used as an assistant means for identifying the crude and sweated Dipsaci Radix.

ABSTRACT

Model organism zebrafish was used to study metabolism of asperosaponin VI from Dipsacus asper Wall. ex Henry for the first time. Metabolic components of asperosaponin VI after exposing to zebrafish for 24 h were identified by high performance liquid chromatography--electrospray mass spectrometry (HPLC-ESI-MS), the separation was performed with a Zorbax C18 column using a binary gradient elution of 0.05% formic acetonitrile--0.05% formic acid water. The quasi-molecular ions of compounds in both negative and positive mode were observed for molecule mass information, and the potential structures were identified by attentive study on the deglycosylation metabolites and one hydroxylation metabolite of asperosaponin VI. The results were highly in consistent with metabolism of asperosaponin VI in rat. It can be concluded that zebrafish model can wonderfully imitate current metabolic model with advantages of small amount of lower cost, far less amount compound, higher efficiency and more simple, and can reflect integrated metabolism results of in vivo method. Zebrafish metabolic model may become a novel organism model for quick predication on metabolism of even mircoamount compound, which can enrich the available models greatly.

ABSTRACT

<p><b>OBJECTIVE</b>To study the effect of growth hormone (GH) combined with Radix Dipsaci on the body growth and the bone mineral content (BMC) of hypophysectomized rats.</p><p><b>METHODS</b>The GH deficiency rats model was established using the hypophysectomized operation through the skull and the throat. Qualified rats were divided into the sham-operation group (n = 15), the negative control group (n = 13), the GH intervention group (n = 13), and the GH combined with Radix Dipsaci group(n = 12). GH (0.25 mg/kg) was subcutaneously injected from the cervical part in the GH intervention group and the GH combined with Radix Dipsaci group at the same time, while equal volume of normal saline was injected to the rest groups. 0.7 mL/100 kg Radix Dipsaci was given by gastrogavage to the GH combined with Radix Dipsaci group at the same time, while equal volume of normal saline was given by gastrogave to the rest groups. The body weight, the tail length, and the body length were measured during the intervention period. Blood was withdrawn after 14-day intervention. The femoral bone and the tibial bone were taken out. The levels of GH, insulin-like growth factor 1 (IGF-1), alkaline phosphatase (ALP), and osteocalcin (OC) were measured. The width of the tibial epiphyseal plate was measured. The bilateral femur bone mineral density (BMD) and BMC were measured using the dual energy X-ray absorptiometry.</p><p><b>RESULTS</b>The body weight, the body length, the length of the femoral bone, the length of the tibial bone, the width of the epiphyseal plate, the levels of the GH, IGF-1, ALP, and OC increased in the GH intervention group and the GH combined with Radix Dipsaci group after 2-week intervention, showing statistical difference when compared with the model group (P < 0.01). But there was no statistical difference in the tail length though it also increased (P > 0.05). There was insignificant difference in the aforesaid indices between the two groups (P > 0.05). Compared with the model group, the BMD of the GH combined with Radix Dipsaci group increased with statistical difference (P < 0.01). Compared with the model group, the BMC of the GH intervention group and the GH combined with Radix Dipsaci group increased with statistical difference (P < 0.01). It was highest in the GH combined with Radix Dipsaci group (P < 0.01).</p><p><b>CONCLUSIONS</b>GH combined with Radix Dipsaci showed unobvious effect on promoting the growth. But it could elevate BMD and BMC, and improve the bone metabolism.</p>

ABSTRACT

A high performance liquid chromatography (HPLC) method was developed for fingerprint of Dipsacus asper. Analysis were carried out on a Zorbax C-18 column by gradient elution using 0.1% phosphoric acid and acetonitrile as the mobile phases. The column was maintained at 25 degrees C, the flow rate was 1 mL x min(-1), and the detection wavelength was set at 205 nm. Asperosaponin VI was selected as reference compound, Seventeen common peaks were selected, and the fingerprint with good precision, stability and repeatability was successfully used to evaluate quality of 24 batches of crude extracts of D. asper. Chemical characteristics of D. asper was analyzed by DAD detection and HPLC-MS techniques with an ESI source. The quasi-molecular ions of compounds in both negative and positive modes were observed for molecule mass information of 33 compounds, and the potential structures of 10 characteristic components were identified by study on the mass spectra of compounds and comparing with reference data and some of standards. The results indicate the HPLC fingerprint of D. asper will show more characters through identification of component structures using an HPLC-ESI-MS method, and will control the quality of D. asper more effectively and reasonable.

ABSTRACT

Pterocephalus sanctus Decne. was subjected to a bioassay guided fractionation in order to follow and identify the active principles that could be responsible for its anti-hepatotoxic property. The aqueous methanol [80%] extract of the defatted powder of Pterocephalus sanctus was chromatographed over silica gel and eluted with gradient petroleum ether/ethyl acetate. Eight fractions were collected and tested for their biological activity using Primary Cultured Monolayer Hepatocytes where the fifth fraction was subjected to a further fractionation. Three compounds were identified as secologanin, loganin and swerosoid and the latter was only found to possess highly anti-hepatotoxic activity. This is the first report of the study of the anti-hepatotoxic activity of P. sanctus growing in Egypt

ABSTRACT

<p><b>OBJECTIVE</b>To develop a quantitative method for the determination of akebia saponin D in root of Dipacus asperoides and provide scientific basis for quality control of D. asperoides.</p><p><b>METHOD</b>An IPLC analytical method was established using Kromasil ODS column with acetonitrile-water (30:70) as mobile phase and the detection wavelength was 212 nm.</p><p><b>RESULT</b>The akebia saponin D in root extract were well separated by this method. The linear range is between 0.582 5-9.32 microg, r = 0.9999. The average recovery and RSD of repeatability are 100.3%, 2.3%, respectively.</p><p><b>CONCLUSION</b>This method is simple, accurate and reliable by evaluating the method validation data and can be used for the quality control of D. asperoides and its preparations.</p>
