ABIETANE DITERPENES FROM SALVIA-NAPIFOLIA

Abstract

From the acetone extract of the roots of Salvia napifolia, eight known diterpenoids-horminone, 7-acetyl-horminone, ferruginol, pachystazone, cryptanol, cryptojaponol, sugiol and microstegiol-and five new diterpenes-6,1 2, 14-trihydroxyabieta-6,8, 11,12-tetraen, 7,20-epoxyroyleanone, 1-oxoferruginol, 6-oxoferruginol and 1 1,12-dioxoabieta-8,13-dien- were obtained. The structures of the new and the known compounds were established by spectral methods.
