Study on triterpenes from roots of Actinidia deliciosa / 中草药

ABSTRACT

Objective: To investigate the chemical constituents from the roots of Actinidia deliciosa. Methods: With 95% ethanol as the extraction solvent, various chromatography techniques were used to separate and purify the constituents and the structures were identified based on spectroscopic data. Results: Three compounds were isolated from the roots of A. deliciosa and identified as lupa-12, 20(30)-diene-2β, 3β, 28-triol (1), 2α, 3β, 19α, 24-tetrahydroxy-12-en-28-ursolic acid (2), and 2α, 3β, 23, 27-tetrahydroxy-12- en-28-ursolic acid (3). Conclusion: Compound 1 is a new triterpenoid named actinidin A.
