[Studies on chemical constituents in n-butyl alcohol extract of roots of Actinidia deliciosa in Guangxi].

Objective: To study the chemical constituents of n-butyl alcohol extract in the roots of Actinidia deliciosa in Guangxi.

Method: 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.

Result: 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).

Conclusion: 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.
