[New diterpenoids, isodoternifolins A and B, from Isodon ternifolius].
Two new diterpenoids, named isodoternifolin A and B, together with seven known compounds were isolated from the ethanol extract of dried stems and leaves of Isodon ternifolius (D. Don) Kudo. Their structures were determined as 7 beta-hydroxy-6 beta, 11 alpha, 15 beta-triacetoxy-7 alpha, 20-epoxyentkaur-16-ene (1) and 6 beta, 7 beta, 15 beta-trihydroxy-11 alpha-acetoxy-7 alpha, 20-epoxy-entkaur-16-ene (2) by chemical and spectral evidence.
