Abstract: The constituents of Rubus amabilis were isolated and purified by silica gel column chromatography,Sephadex LH-20,macroporous adsorption resin and TLC.The structures of the purified compounds were elucidated on the basis of spectral data and physiochemical properties.Eight compounds were isolated and their structures were identified as:4-acetoxy-3-methoxybenzoic acid (1), 2-(β-D-glucopyranosyloxy)-6-hydroxybenzoic acid (2), vanillic acid (3), resveratrol (4), 2,6-dimethoxy-4-hydroxyphenol-1-O-β-D-glucopyranoside (5),trans-4-hydroxy cinnamic acid (6),caffeic acid (7) and gallic acid (8).Compound 1 was a new natural product.Compounds 2-7 were isolated from Rubus amabilis for the first time.

Key words: Rubus amabilis Focke, Rosaceae;phenolic compounds;structural elucidation
