Four compounds, veratrylidenehydrazide, 3,3'-di-O-methylquercetin, dro
xy-3(3'-methoxy-4'-hydroxy)-5-methoxyisoflavone and 3',7-di-O-methylqu
ercetin were isolated from the methylene chloride extract of dried lea
ves of Wedelia biflora. The structures were elucidated from spectrosco
pic evidence. The third compound possessed antifungal and boll weevil
antifeedant activity while the fourth showed antifungal activity.
