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--6,12,14-trihydroxyabieta-6,8,11,12-tetraen, 7,20-epoxyroyleanone, 1-oxoferruginol, 6-oxoferruginol and 11,12-dioxoabieta-8,13-dien-- were obtained. The structures of the new and the known compounds were established by spectral methods.
