A new diterpenoid, fritillebic acid (1) and four new diterpenoid dimers, fritillebins A (2) and B (3), and fritillebinides A and B, were isolated from a crude drug, bulbs of Fritillaria ebeiensis G. D. Yu et G. Q. Ji. The structures of compounds 1—3 were determined to be ent-3β-acetoxy-16β-kauran-17-oic acid (1), ent-16β-hydroxykauran-17-yl ent-3β-acetoxy-16β-kauran-17-oate (2), and ent-3β-acetoxy-16β-hydroxykauran-17-yl ent-3β~ acetoxy-16β-kauran-17-oate (3), respectively, on the basis of spectroscopic and chemical evidence. © 1995, The Pharmaceutical Society of Japan.
