Study on Preparation of Salidroside and Polysaccharide in Rhodiola crenulata
摘要
Abstract
Objective:To optimize the preparation process of salidroside and polysaccharide in Rhodiala crenulata. Methods; Water-extraction and alcohol-precipitation was used The effect of added water volume, decoction time and frequency on water-extracting process was investigated by L,(3 ) orthogonal design using extraction rate,content of salidroside and polysaccharide as the assessment indexes. The effect of liquor strength and ethanol concentration on alcohol-precipitating process was investigated as well,using content of salidroside and polysaccharide as the assessment indexes. Results;The optimum conditions for water-extracting process were as follows; decocting 3 times,and each time adding 8 fold of water and extracting 2 h. For alcohol-precipitating process,it was that liquor strength was 0.4 g/mL,and ethanol concentration in liquor was 70%. Conclusion;The optimized process has guidance for the development and comprehensive utilization of this plant关键词
