[Study on sterols and triterpenes from the stems of Akebia quinata].Zhong Yao Cai. 2005 Dec; 28(12):1060-2.ZY
The ethanol extract from Akebia quinata was seperated by dichloromethane, n-butanol in sequence. Six compounds were isolated and identified as beta-sitosterol (I), delta(5,22) stigmasterol (II), oleanolic acid (III), hederagenin (IV), daucosterol (V), delta(5,22) stigmasterol-3-O-beta-D-glycopyranoside (VI). Compound VI was isolated from Akebia plants for the first time.
