摘要
目的考察影响天麻中天麻素的提取因素。方法采用正交试验法,以提取液中醇浸膏收率及天麻素的含量为考察指标。结果提取的最佳条件70℃下,用40%乙醇提取3次,每次2h,6倍量乙醇。结论所用工艺稳定可行。
Objective To study the extraction conditions of gastrodin in Gastrodia elate. Methods Orthogonal experiment design was adopted. The index was the quantity of alcohol extract and the content of gastrodin in the extract .Results The opimum extracting conditions of gastrodin were as foUows： 70℃, 6 times of 40% alcohol, extracting for three times, 2h each time. Conclusion The extraction procedure is stable and operative.
