摘要
Two new flavonol glycosides, artabotryside A (1), artabotryside B (2), and three known flavonoids taxifolin (3), glucoluteolin (4) and apgeinn-7-O-apiosyl (1- 2)glucoside (5) were isolatal from the leaves of Artabotrys hexapetalus (Annonaceae). The structures of 1 and 2 were establishcd as quercetin-3 - O-a- L-rhamnopyranosyl (1- 2)-a-L-arabinofuranoside (1 ) and kaempferol -3 - o -a-L- rhamnopyransyl (1 - 2)-a-L-arabinofurano-side (2), on the bases of spectal analysis
