flavonoids (or bioflavonoids), also collectively known as Vitamin P and citrin, are a class of plant secondary metabolites.

They show anti-allergic, anti-inflammatory, anti-microbial and anti-cancer activity.

Flavonoids (both flavonols and flavanols) are most commonly known for their antioxidant activity in vitro. Their in vivo effect has not been proven yet, but the degradation of vitamin C can be hindered by flavonoids.

Flavonoids could also induce mechanisms that help kill cancer cells and inhibit tumor invasion.

Bioflavonoids like rutin, monoxerutin, diosmin, troxerutin and hidrosmin have vasoprotective proprieties.
