摘要：

The new diterpene acids were isolated from the leaves of Larix kaempferi, together with two known sesquiterpenes, (-)-alpha-cadinol and oplopanone, and 10 known diterpenes, larixol, dehydroabietinol, 7-oxodehydroabietinol, 7-oxodehydroabietic acid, 9 alpha,13 alpha-epidioxyabiet-8(14)-en-18-oic acid, 9 beta,13 beta-epidioxyabiet-8(14)-en-18-oic acid, dehydroabietic acid, 7 alpha-hydroxydehydroabietic acid, 8 alpha,9 alpha,13 alpha,14 alpha-diepoxyabietan-18-oic acid and 15-hydroxydehydroabetic acid. The new acids and their methyl esters were characterized as methyl abieta-8,11,13,15-tetraen-18-oic acid, methyl 16-nor-15-oxodehydroabietic acid and methyl 12,15-dihydroxydehydroabietic acid, on the basis of chemical and spectroscopic evidence.
