RESUMO
OBJECTIVE: To study chemical constituents from petroleum ether-soluble parts of cones of Platycladus orientalis. METHODS: The compound were isolaeed by repeated column chromatography of silica gel and Sephadex LH-20. The structures were elucidated by physicochemical properties and spectrum analysis. RESULTS: Seven constituents were isolated and identified as sandaracopimaric acid (1), 6alpha-hydroxy sandaracopimaric acid (2), ent-isopimara-8 (14), 15-dien-3beta, 19-diol (3), ent-isopimara-8 (9), 15-dien-3beta-ol (4), ent-isopimara-8 (14),15- dien-3beta-ol (5), isocupressic acid (6) and 15-acetylisocupressic acid (7). CONCLUSION: Compounds 2 and 7 are isolated from this genus for the first time.
