Chemical Constituents from the Aerial Parts of Lysimachia clethroides

摘要

A new glyceroglycolipid, 1-O-（9Z, I 2Z-octadecadienoyl）-3-O-[β-D-galactopyranosyl-（1→6）-O-β-D-galactopy- ranosyl-（1→6）-a-D-galactopyranosyl] glycerol （1）; a new ester, 3-carboxyethyl-3-hydroxyglutaric acid 1,5-dime- thyl ester （2）, together with four known compounds were isolated from the ethanolic extract of the aerial parts of Lysimachia clethroides. The structures of compounds 1 and 2 were elucidated on the basis of physical data analy- sis （1D and 2D NMR, HR-ESIMS） and chemical evidence.
