- Abstract
- Four flavonoide glycosides and (-)-Epicatechin were isolated from the aqueous extracts of dried whole part of Lysimachia clethroides Duby(Primulaceae). They were 3-O-Methyl-quercetin-7-O-[alpha-L-rhamnopyranosyl (1-2) glucopyranoside], Quercetin-3-O-beta-D-glucopyranoside, Kaempferol-3-O-beta-D-glucopyranoside, Kaempferol-3-O-[alpha-L-rhamnopyranosyl (1-6)-beta-D-glucopyranoside] and (-)-Epicatechin. 3-O[alpha-L-rhamnopyranosy] (1-6)-beta-D-glucopyranoside] and (-)-Epicatechin. 3-O-Methyl-quercetin-7-O-[alpha-L-rhamnopyranosyl (1-2)-beta-D-glucopyranoside] and (-)-Epicatechin were first isolated from this plant. Their structures were elucidated by spectral analysis [1H-, 13C- NMR, 1H-1H-COSY, DEPT-analysis, HMQC(Heteronuclear multiple quantum coherence), FAB-MS].
