K. Shiojima et al., FERN CONSTITUENTS - ADIANTUM-CUNEATUM .1. 3 NEW TRITERPENOIDS, GLAUCANOL-B ACETATE, 7-BETA,25-EPOXYFERN-8-ENE AND 25-NORFERN-7-EN-10-BETA-YL FORMATE, Chemical and Pharmaceutical Bulletin, 45(4), 1997, pp. 636-638
Sixteen triterpenoids including three new compounds, viz. glaucanol B
acetate (1), 7 beta,25-epoxyfern-8-ene (2), and 25-norfern-7-en-10 bet
a-yl formate (3) were isolated from the fresh leaves of Adiantum curre
atum. Their structures were elucidated on the basis of spectral data.
