摘要：

From flowerheads of Buphthalmum salicifolium the new acylated flavonol glycosides quercetagetin 7-O-(6"-O-isobutyryl)-beta-glucoside, quercetagetin 7-O-(6"-O-isovaleryl)-beta-glucoside, quercetagetin 7-O-(6"-O-2-methylbutyryl)-beta-glucoside, patuletin 7-O(6"-O-isobutyryl)-beta-glucoside and the new acylated caffeoylquinic acid derivative, 1-isobutyryl-3,5-dicaffeoylquinic acid were is elated, as well as ten common flavonoid glyco sides together with three sesqui terpenes, 10-acetoxy-8, 9-epoxythymolisobutyrate and S-(+)-dehydrovomifoliol. All structures were mainly established on the basis of UV-, MS- and NMR (H-1,C-13, H-1-H-1 COSY, HMQC and HMBC) spectroscopic data. (C) 1999 Elsevier Science Ltd. All rights reserved.
