Abstract
Two new ent-kauranoid diterpenoid dimers, fritillebin C (1) and fritillebin D (2), were isolated from the bulbs of Fritillaria ebeiensis G.D. Yu and G.Q. Ji. Their structures were determined to be ent-16beta-hydroxy-kauran-17-yl ent-16beta3-kauran-17-oate (1); ent-16alpha-hydroxy-kauran-17-yl ent-16beta-kauran-17-oate (2) by means of spectral analysis and chemical evidence.
