Abstract:
Objective To study the optimum ethanol extraction process of total flavonoids in Lophatherun gracile Brongn. Methods The extraction of total flavonoids was choosen as the assessment index. Ethanol volumn extracting time and times were the studing factors. The optimum ethanol extraction process was selected with the orthogonal design. Results The optimum ethanol extracting process conditions were as follows:adding 18 fold of 75% ethanol,extracting for 1.0 h and one in all. Ethanol dosage was the predominant influencing factor. Conclusion This optimum extradion process of total flavonoids in Lophatherum gracle Brongn is reliable.
