[Studies on chemical constituents in n-butyl alcohol extract of roots of Actinidia deliciosa in Guangxi].Zhongguo Zhong Yao Za Zhi. 2008 Jun; 33(11):1275-7.ZZ
To study the chemical constituents of n-butyl alcohol extract in the roots of Actinidia deliciosa in Guangxi.
The constituents were separated with various chromatographic techniques and their structures were elucidated by means of physicochemical properties and the analysis of their spectral data.
Six compounds were isolated and identified as eriantic acid B (1), 2alpha, 3beta, 24-trihydroxyursa-12-en-28-oic acid (2), 2alpha, 3alpha, 24-trihydroxyursa-12-en-28-oic acid (3), 2alpha, 3alpha, 23-tri-hydroxyursa-12, 20 (30)-dien-28-oic acid (4), 2alpha, 3alpha, 24-trihydroxyursa-12, 20 (30)-dien-28-oic acid (5), n-butyl-O-beta-D-fruto-pyranoside (6).
Compounds 1-4, 6 were obtained from this plant for the first time. Compound 6 was obtained from the genus Actinidia for the first time.
