Flavonoid glycosides of Alchemilla vulgaris L.

Phytotherapy Research, 1998
From the methanol extract of Alchemilla vulgaris L. (Rosaceae) four flavonoid glycosides were obtained. The isolated compounds were characterized by their spectral and chromatographic data. The known pharmacological properties of flavonoids may explain the use of this plant in popular medicine. © 1998 John Wiley & Sons, Ltd.
