OBJECTIVE To study the ethyl acetate-soluble chemical constituents of Callicarpa kwangtungensis. METHODS The chemical constituents were isolated by column chromatography on silica gel, Sephadex LH-20 and MPLC. Their chemical structures were elucidated on the basis of special analysis. RESULTS Seven compounds were isolated from ethyl acetate part, whose structures were elucidated as caffeic acid(1),2α,3α, 19α-trihyhydroxy-urs-12-en-28-O-β-D-glucopyranoside (2),2α,3, 19α-trihyhydroxy-olean-12… Expand
