Chemical constituents from the buds of Lonicera macranthoides in Sichuan, China

摘要

The phytochemical investigation of the dried buds of L macranthoides Hand. -Mazz. Symb. Sin, collected in Sichuan, China resulted in the isolation of three aliphatic glycosides (1-3), a caffeoyl glucoside (4), a secoiridoid glycoside (5), and two caffeoylquinic acid analogs (6 and 7). Among them, compound 1 was novel and identified as n-butyl-beta-D-apiofuranosyl(1 -> 6)-beta-D-glucopyranoside based on the detailed spectroscopic analyses and chemical studies. Compounds 1-4 were isolated for the first time from Caprifoliaceae family; compounds 5-7 were isolated for the first time from L. macranthoides. The chemotaxonomic significance of these compounds was summarized
