摘要:

以杜仲鲜皮作为原料,水为提取溶剂,采用单因素实验方法探讨料液比(1∶5~1∶60 g·mL-1)、提取时间(10~120 min)和提取温度(30~90℃)对杜仲皮总固形物得率及活性成分提取率的影响,并确定单因素实验最佳提取工艺为:料液比1∶20,提取时间60 min,提取温度60℃。此条件下,总固形物得率为11.61%,其中活性成分绿原酸得率为0.073%,桃叶珊瑚苷得率为0.704%,京尼平苷得率为0.122%,松脂醇二葡萄糖苷得率为0.108%。水提取杜仲皮成分,方法简单,无环境污染和溶剂回收问题,本文为杜仲鲜皮活性成分提取和开发利用提供的实验依据。

Abstract: We investigated the total solid and the active component yields from fresh Eucommia bark by singlefactor experiments of aqueous extraction under the liquid ratio of 1∶20 to 1∶60 g·mL-1, extraction time from 10-120 min, and extraction temperature from 30℃ to 90℃. Under the optimum extraction processes of singlefactor experiment, the total solid yield was 11.61%, and the extraction yields of chlorogenic acid, aucubin, geniposide and pinoresinol diglucoside were 0.073%, 0.704%, 0.122% and 0.108%, respectively. Aqueous extraction has advantages of simple process without environmental pollution and solvent recovery.
