摘要
采用分光光度法、TLC、HPLC、MS等,对白藜芦醇苷水解产物进行了鉴定;通过单因子和多因子的正交试验,确定了白藜芦醇苷水解产生白藜芦醇的适宜工艺条件,即在温度65℃,提取液为体积分数8%HCl、75%甲醇,反应5h;在此条件下,从虎杖粉末中提取的白藜芦醇可以达到2.06%。
Using spectrophotography ,TLC ,HPLC,MS and others means to identify the hydrolysates of polydatin Through the single factor and the multi -factorg orthogonal test, we determined the optimal technical conditions of polydatin hydrolyzes into resveratrol ,which are 65℃ , 8% of hydrochloric acid concentration, 75% of methanol concentration and 3h of reacting time; Under the optimum conditions, the concentration of resveratrol is extracted from Polygonum of resveratrol can reach 2.06 percent.
