【摘要】 [Objective] To optimize the extraction technology of total flavonoids from Vitex negundo L.var.cannabifolia(Sieb.et Zucc.)Hand.-Mazz.and compare their contents in different parts.[Method] Taking the extraction rate of total flavonoids as index,L9(34)orthogonal test was used to optimize the extraction process of total flavonoids from leaves,stems,flowers,fruits and roots of Vitex negundo L.var.cannabifolia(Sieb.et Zucc.)Hand.-Mazz.by microwave method.Then,contents of total flavonoids in different parts were compared.[Result] The optimal extraction technology of total flavonoids was as follows:ethanol concentration of 30%,extraction temperature of 90 ℃,solid-liquid ratio of 1∶30 and microwave irradiation time of 12 min.Under this condition,the contents of total flavonoids from leaves,stems,flowers,fruits and roots were 9.33%,3.19%,8.52%,5.67% and 4.31%,respectively.[Conclusion] This study could provide theoretical basis for the proper development and utilization of Vitex negundo L.var.cannabifolia(Sieb.et Zucc.)Hand.-Mazz.resources.
