A novel anthocyanidin glycoside from the rhizomes of Abacopteris penangiana.
A novel anthocyanidin glycoside, abacopterin J (1), together with the known eruberin B (2) and eruberin C (3) was isolated from the fern Abacopteris penangiana (Hook.) Ching. The structure of the new compound 1 was elucidated on the basis of extensive spectroscopic analysis, including HSQC, HMBC, ((1))H-((1))H COSY and ROESY, and chemical evidence. Abacopterin J is the first example of an anthocyanidin glycoside isolated from natural sources, which is comprised of a flavan and an anthocyanidin moiety.
