title: [A new flavonoid from Lysimachia foenum-graecum].
abstract: The aim of the study was to look for the chemical constituents of the herb of Lysimachia foenum-graecum. The herb of Lysimachia foenum-graecum was extracted with 70% EtOH. The isolation and purification was performed with a combination of multi-column chromatography and the structure was determined by spectral analysis. The flavonoid compound was obtained and elucidated as kaempferol-7-O(4"-(E)-p-coumaroyl-)-alpha-L-rhmanopyranosyl)-3-O-beta-D-glucopyranosyl (1-->4)-alpha-L-rhmanopyranosyl (1-->2)-beta-D-glucopyranoside. It is a new flavonoid compound.
