Studies on the Chemical Constituents of Genus Lysimachia. I

On the Whole Parts of Lysimachia japonica THUNB. and Lysimachia clethmides DUBY

Abstract

The chemical constituents of the methanol extracts of dried whole parts of Lysimachia japonica THUNB. and L. clethroides DUBY (Primulaceae) were studied. Salicylic acid and flavonol glycosides, hyperin, rutin and kaempferol-3-O-rutinoside were isolated from the former and four flavonol glycosides, astragalin, isoquercitrin, kaempferol-3-O-rutinoside and kaempferol-3-O-(2, 6-di-O-rhamnopyranosylglucopyranoside) were isolated from the latter. Salicylic acid and kaempferol-3-O-(2, 6-di-O-rhamnopyranosylglucopyranoside) were first isolated from Lysimachia plants.
