摘要：

From the aerial parts of Melampodium divaricatum (Rich. in Pers.) DC, Asteraceae, four new doubly and eight new triply acylated 2-hydroxythymol 3-O-beta-D-fucopyranosyl-(1-->3)-beta-D-fucopyranosides (seven compounds) and 2-hydroxythymol 3-O-beta-D-fucopyranosyl-(1-->3)-beta-D-quinovopyranosides (five compounds) were isolated and their structures established by spectroscopic methods. The acids involved in the acylation of the sugar moieties are angelic, isovaleric, 2-methylbutyric, and acetic acid. (C) 1999 Elsevier Science Ltd. All rights reserved.
