Objective To study the chemical constituents of the sterns and leaves parts of Abies chensiensis. Methods The isolation and purification were carried out by HP-20 macroporous resin, Sephadex LH-20, silica gel column chromatography, semi-preparative HPLC. Their structures were elucidated on the basis of physicochemical properties and spectroscopic data. Results Twenty-four compounds were isolated and elucidated from the sterns and leaves parts of A. chensiensis, their structures were identified as 7,14,24-mariesatrien-26,23-olide-3α,23-diol(1),(23 R)-3α-hydroxy-9,19-cyclo-9β-lanost-24-en-26,23-olide(2), 7-oxocallitrisic acid(3), 23-hydroxy-3-oxomariesia-8(9),14,24-trien-26,23-olide(4), neoabiestrine E(5), 3-oxo-9β-lanosta-7,24-dien-26,23 R-olide(6), 7,14,22 Z,24-mariesatetraen-26,23-olide-3-one(7),(+)-rel-3α-hydroxy-23-oxocycloart-25(27)-en-26-oic acid(8), cycloart-25-en-3β,24-diol(9), neoabiestrine H(10), 3-oxo-24,25,26,27-tetranolanost-8-en-23-oic acid(11), abiesadine C(12), 13β-epidioxy-8(14)-abieten-18-oic acid(13), dehydroabietic acid(14), 15-hydroxydehydroabietic acid(15), methyl 18-methoxydehydroabietate(16), 7β-hydroxy dehydroabietic acid(17), dehydroabietan-18-ol(18), centdaroic acid(19), abietic acid(20), 6,8,11,13-abi-etatrien-18-oic acid(21), abiesadine B(22), abiesadine N(23), 12β-hydroxyabietic acid(24). Conclusion All compounds are isolated from the plants of A. chensiensis for the first time, and compound 11 is isolated from the Abies genus for the first time.
