Flavonoids from Ulex airensis and Ulex europaeus ssp. europaeus

J Nat Prod. 2002 Feb;65(2):175-8. doi: 10.1021/np010147j.

Abstract

From the dichloromethane extract of Ulex airensis three new isoflavonoids, ulexin C (1), ulexin D (2), and 7-O-methylisolupalbigenin (3), were isolated and characterized by spectroscopic methods. Ulexin D (2) was also identified from the dichloromethane extract of Ulex europaeus ssp. europaeus. Together with these new metabolites, 18 compounds of previously known structures were isolated and identified from both species. The antifungal activity of these compounds was tested against Cladosporium cucumerinum by a bioautographic TLC assay.
