|The contents of parishin, parishin B and parishin C in traditional decoctions and commercial extracts of Gastrodiae Rhizoma[Reference: WebLink]|
|The contents of parishin, Parishin B and parishin C in six traditional decoctions and six commercial extracts of Gastrodiae Rhizoma were analyzed by high performance liquid chromatography. Separation and quantitation were performed on a Cosmosil 5C18-AR column by gradient elution with varied ratios of 0.1 % (v/v) phosphoric acid: methanol as the mobile phase at a flow rate of 1.0 mL/min and detection at 222 nm. Sulfamethoxypyridazine was used as the internal standard. The contents of parishin, Parishin B and parishin C in traditional decoctions of Gastrodiae Rhizoma were 2.7±0.5 mg/g, 2.3 ± 0.2 mg/g and 1.6 ± 0.3 mg/g, whereas commercial extracts contained 6.9± 0.9 mg/g, 2.7± 0.3 mg/g and 1.6± 0.1 mg/g, respectively. Based on our results, the maximum daily doses of parishin, Parishin Band parishin C in traditional decoctions of Gastrodiae Rhizoma were 24.1± 4.5 mg, 20.4± 2.0 mg and 14.4± 2.6 mg compared to 15.6± 1.4 mg, 6.5± 1.1 mg and 4.1± 0.7 mg in commercial extracts, respectively. The daily dose of parishin, Parishin Band parishin C were higher in traditional decoctions than in commercial extracts.|

|Comparison on Chemical Constituents and Pharmacological Effect of Gastrodiae Rhizoma Between Traditional Processing and Integration Processing[Reference: WebLink]|
|To elucidate the rationality of integration processing technology based on comparison on chemical constituents and pharmacological effect of Gastrodiae Rhizoma between traditional processing and integration processing. Method: Taking contents of gastrodin and parishins as indexes,chemical constituents difference in Gastrodiae Rhizoma between traditional processing and integration processing was compared,effects of Gastrodiae Rhizoma on eclampsia model induced by pentylenetetrazole were observed to compare products with different processing technology. Result: Contents of gastrodin,parishin A,Parishin B,parishin C and parishin E in products of integration processing were 0. 79%,2. 04%,0. 91%,0. 23% and0. 57%,they were 0. 39%,1. 12%,0. 64%,0. 15% and 0. 54% in products of traditional processing. The anti-eclampsia effect of Gastrodiae Rhizoma produced with integrated processing technology was better thantraditional processing technology. Conclusion: Compared with the traditional processing technology, the integrated processing technology is better in guaranteeing the quality of pieces,reducing the cost of production and increasing the production efficiency.|

|Study on active ingredient and mechanism in preventing vascular dementia of Tianzhusan coming from Tujia medicine.[Pubmed: 26697697]|
|To make clear of the absorbed components of Tianzhusan (TZS) and its possible mechanism in preventing vascular dementia (VD), the rats' models of VD were prepared by a permanent ligation of the bilateral common carotid arteries. After 60 days, rats were administrated with TZS for 0.1 g x kg(-1), and the volume is 0.02 mL x g(-1). After 3 days, the medicated serum was prepared and detected by UPLC, and then we predicted the possible chemical structure of the absorbed components of TZS. According to the absorbed components, the potential targets of TZS were found by ligand profiling of Discovery Studio 3.5. All of these target genes were submitted to DAVID onine for gene set enrichment analysis (GSEA). The 5 absorbed components of TZS have been predicted, and four of them have been identified as Parishin B, parishin C, parishin, pennogenin-3-O-alpha-L-rhamnopyranosy-(1-->2)-beta-D-glucoside. Through reverse finding targets, we got 861 pharmacophore models and 9 pathways from KEGG, BIOCARTA after document verification. These results showed that the efficacy mechanism of TZS on VD perhaps were be related with these absorbed components and pathways. If the traditional herbs could be proved effective by efficacy tests, the serum pharmacochemistry, computer-aided drug design, system biology and other technologies can be used in the next experiments, which will be beneficial to fast discovery of material basis and mechanisms of traditional medicine coming form ethnic minorities.|
