title: A new flavonoside from Leonurus heterophyllus.
abstract: In a chemical investigation on the flavone composition of Leonurus heterophyllus a new flavonoside has been isolated. By means of physico-chemical evidences and spectral analysis its structure has been established as quercetin-3-O-[3-(4-hydroxy-3,5-dimethoxybenzyl)-alpha-L-rhamnopyranosyl]-(1-->6)-beta-D-galactopyranoside (1).
