Unusually stable monoacylated anthocyanin from purple yam dioscorea alata
摘要:
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.
