[Studies on chemical constituents from root of Actinidia macrosperma].

OBJECTIVE:To study the chemical constituents of root of Actinidia macrosperma. METHOD:Chromatographic methods were used to isolate compounds from A. macrosperma and spectroscopic methods were used to identify the structures of the isolated compounds. RESULT:Eight compounds were obtained and identified as 12-oleanene-2alpha, 3alpha, 24-triol (1), isotachioside (2), asiatic acid (3), catechin (4), epicatechin (5), ursolic acid (6), beta-daucosterol (7), beta-sitosterol (8). CONCLUSION:All these compounds were isolated from this plant for the first time, compound 1, 2 were obtained from this genus for the first time.
