Absorption of acylated anthocyanins from purple yam extract in rats.

Purple yam (Dioscorea alata L.) is a tuber widely distributed in the tropics and subtropics. We previously isolated several acylated anthocyanins from purple yam.

New acylated anthocyanins from purple yam and their antioxidant activity.

Purple yam (Dioscorea alata L.), which is widely distributed in tropical and subtropical regions, is characterized by its color and viscosity. Previous studies have shown that purple yams contain a variety of acylated anthocyanins that exhibit higher levels of antioxidant activity than the corresponding nonacylated compounds.
