Two new anthocyanins, cyanidin and peonidin 3-gentiobioside acylated with sinapic acid, have been isolated from the tuber of Dioscorea alata L. 'King yam' originated from Sri Lanka.These structures are elucidated by spectroscopic methods.

Alatanin C isolated from the tuber of purple yam Dioscorea alata. is the first discovered unusually stable monoacyalated anthocyanin in nuetral aqueous solutions. The stability is ascribed to the intramolecular stacking of sinapic acid and to the chiral self-association of anthocyanidin nuclei.
