摘要：

Four new 25,26,27-trisnorlanostene-type triterpenoids were isolated from the stem bark of Pinus luchuensis, together with five known compounds. These new compounds were characterized as 25,26,27-trisnor-3 alpha-hydroxy-lanost-9(11)-en-24-oic acid (1), 25,26,27-trisnor-3 alpha-methoxy-lanost-9(11)-en-24-oic acid (2), 25,26,27-trisnor-3 beta-methoxy-lanost-9(11) acid (3), and 25,26,27-trisnor-3-oxo-lanost-9(11)-en-24-oic acid (4) on the basis of MS and NMR evidence.
