Chemical constituents in root of Actinidia chinensis / 中草药

ABSTRACT

Objective: To study the chemical constituents in the root of Actinidia chinensis. Methods: The chemical constituents were isolated and purified by silica gel column and their structures were identified on the basis of spectral methods. Results: Eleven compounds were isolated and identified as γ-quinide (1), stearyl-β-D-glucopyranoside (2), daucosterol (3), (-)-epi-catechin (4), 2α,3α,24-trihydr-oxyurs-12-en-28-oic acid (5), 3-epi-corosolic acid (6), ursolic acid (7), n-butyl-β-D-fructopyranoside (8), sucrose (9), lignocericacid (10), and β-steriol (11). Conclusion: Compound 1 is isolated for the first tine as natural substance, and compounds 2,8, and 10 are isolated from A. chinensis for the first time.
