Article abstract of DOI:10.1016/0031-9422(88)84117-7

Key Word Index-Illicium anisatum; Illiciaceae; prenylated flavan-3-ols; flavan-3-ols; procyanidins; tannins.Two prenylated flavan-3-ols were isolated from Illicium anisatum and their structures characterized by chemical and spectroscopic means as 8-(3,3-dimethylallyl)-(+)-catechin and 6-(3,3-dimethylallyl)-(+)-catechin.In addition, a new proanthocyanidin was isolated, together with several known compounds.The structure of the procyanidin was established as catechin-(4α<*>8)-epicatechin-(4β<*>8)-catechin.
