摘要：

From the gum-resin of Ailanthus grandis six pregnane, two cholestane, two hopane, one lupane and one gammacerane derivatives have been isolated. One, 3-alpha-acetyloxy-5-alpha-pregnan-16-one, is a new compound. Four, 20S-acetyloxy-4-pregnene-3,16-dione, 16-beta-acetyloxy-pregn-4,17(20)-trans-dien-3-one, gammacerane-3,21-dione and 3-alpha-acetyloxy-5-alpha-pregn-17(20)-(cis)-en-16-one, are new natural products. Their structures were established by UV, IR, MS, H-1 and C-13 NMR spectroscopy and two-dimensional NMR techniques (COSY, HMQC and HMBC).
