robustaflavone/hepatitis

Robustaflavone, a naturally occurring biflavanoid isolated from Rhus succedanea, was found to be a potent inhibitor of hepatitis B virus (HBV) replication in 2.2.15 cells, with an effective concentration (EC50) of 0.25 microM, and a selectivity index (SI, IC50/EC90) of 153. Robustaflavone

BACKGROUND Doradilla is a plant that has a long history in the Mexican traditional system of medicine for gall and renal stones, diuresis, stomach and liver inflammation among other diseases. Major components isolated from these plants include biflavonoids as amentoflavone (1), robustaflavone (2)

Four flavone compounds were isolated from the effective fractions inhibiting xanthine oxidase (XOD) of the medicinal plant Selaginella labordei with anti-virus activity, and the structures were elucidated as 4'-methylether robustaflavone (1), robustaflavone (2), eriodictyol (3) and amentoflavone
