Abstract:
Silica gel column chromatography was used for the isolation and purification of the chemical constituents of the pericarp of Illicium macranthum. From dichloromethane-EtOAc (1:1) fraction and EtOAc fraction of the methanol extracts, eleven compounds were identified on the basis of chemical and spectral data. Two new compounds were elucidated to be 6-deoxyneomajucin (1) and 2-oxo-6-deoxyneomajucin (2), along with nine known compounds 6-deoxypseudoanisatin (3), pseudoanisatin (4), anisatin (5), pseudomajucin (6), protocatecheuic acid (7), shikimic acid (8), shikimic acid methylester (9), beta-sitosterol (10) and daucosterol (11). Compounds 1 and 2 are new majucin-type sesquiterpene lactones.
