栽培管花肉苁蓉中苯乙醇苷的乙醇提取工艺

Phenylethanoid Glycosides Extracting Method from Cultivated Cistanche tubulosa(Schenk)R.Wight by Ethanol

探索了用乙醇回流法从栽培管花肉苁蓉中提取苯乙醇苷类物质的工艺流程。通过单因素和响应面实验,对影响苯乙醇苷提取的因素进行了探讨和研究,运用响应面分析法确定了提取工艺的最优化条件:提取温度为60℃,料液比(g∶mL)为1∶12.8,提取时间为3.75 h,乙醇体积分数为68.2%,提取次数2次。在此条件下苯乙醇苷的得率为5.76%。

The technology of extracting phenylethanoid glycosides by ethanol from the cultivated Cistanche tubulosa （Schenk）R. Wight was studied in this article. The factors affecting the extraction were explored and studied. By the response surface analysis, the optimal parameters were obtained as following： temperature of 60℃, phase ratio of solid to liquid（g ： mL） of 1 ： 12.8, extraction time of 3. 5 h, ethanol to whole extraction system in volume of 68. 2% , and exaction in two times. The extraction yield reached 5.76%.
