Structures of two diterpenoid dimers from bulbs of Fritillaria ebeiensis.
A new ent-kaurane diterpenoid dimer, fritillebinide C(1) together with one known diterpenoid dimer fritillebinide B (2) were isolated from the bulbs of Fritillaria ebeiensis G.D. Yu et G.Q. Ji. Compound 1 has been determined to be ent-3beta-acetoxy-kauran-16beta,17-acetal ent-16beta-kauran-17(S)-aldehyde(1) by means of spectral analysis and chemical evidence.
