CHEBI:8881 ·resolve ·ANTIVIRAL ·EXACT SEEDED

A biflavonoid that is obtained by oxidative coupling of two molecules of apigenin resulting in a bond between positions C-3 of the hydroxyphenyl ring and C-6 of the chromene ring. Isolated from Thuja orientalis and Rhus succedanea it exhibits antioxidant, cytotoxic and anti-hepatitis B activity. — ChEBI
