Abstract:
AIM To study the chemical constituents from the twigs and leaves of Cryptomeria fortunei Hooibrenk ex Otto et Dietr.METHODS The ethyl acetate fraction of 95％ ethanol extract from C.fortunei was isolated and purified by silica,MCI,and Sephadex LH-20 column,then the structures of obtained compounds were identified by physicochemical properties and spectral data.RESULTS Eleven compounds were isolated and identified as isopimaric acid (1),sandaracopimaric acid (2),acetylisocupressic acid (3),imbricataloic acid (4),isocupressic acid (5),pinifolic acid (6),13-epicupressic acid (7),19-acetylagathadiol (8),agatadiol (9),phytol (10),elemol (11).CONCLUSION Compounds 1-10 are identified as diterpenoids and compound 11 is identified as sesquiterpenoid;Compounds 2,3,6-11 are obtained from this plant for the first time.
