Abstract

This article investigates the absorption of acylated anthocyanins from purple yam (Dioscorea alata L.) extract in rats. Following oral administration of a sugar-free purple yam extract, characteristic acylated anthocyanins were detected in rat plasma within 15 minutes, indicating rapid absorption in their intact forms, and were subsequently excreted in urine, though at low recovery rates (approximately 0.014%). The study also identified phenolic acids, such as sinapic and ferulic acid glucuronides, in plasma and urine, suggesting metabolic transformation of anthocyanins by digestive processes or gut microbiota. These findings provide the first evidence of in vivo absorption and metabolism of purple yam acylated anthocyanins in rats, highlighting their potential bioavailability and metabolic fate.
