OBJECTIVE
To optimize the conditions for the extraction of ecdysterone from Stemmacantha uniflora.
METHODS
Conditions for the extraction were studied by three different methods as guided by the content of ecdysterone and solid material that present in the extract.
RESULTS
Methanol was the best solvent, water the second, ethanol was greatly effected by concentration. Ultrasonic extraction had a good efficiency with short time. The time of cool extraction was too long, its efficiency was inferior to the other methods.
CONCLUSION
The best methods for the extraction of ecdysterone from Stemmacantha uniflora was methanol reflux extraction.
目的
优化从漏芦中提取蜕皮甾酮的条件。
方法
以提取物中蜕皮甾酮含量和固体物质为指标，采用三种不同方法研究提取条件。
结果
甲醇是最佳溶剂，水次之，乙醇受浓度影响较大。超声提取效率高且时间短。冷浸提取时间过长，效率低于其他方法。
结论
从漏芦中提取蜕皮甾酮的最佳方法是甲醇回流提取。
