isoflavonoids, derived from 3-phenylchromen-4-one (3-phenyl-1,4-benzopyrone) structure
neoflavonoids, derived from 4-phenylcoumarine (4-phenyl-1,2-benzopyrone) structure.<unk> s are most commonly known for their antioxidant activity. However, it is now known that the health benefits they provide against cancer and heart disease are the result of other mechanisms.<unk> s are also commonly referred to as bioflavonoids in the media – the terms are equivalent and interchangeable, for<unk> s are biological in origin.
