GC-MS Analysis of Chemical Components of Taxus Chinensis Var . Mairei Seeds

The extracts of petroleum ether, methanol, ethyl acetate and ether from Taxus chinensis var. mairei seeds were analyzed by GC-MS, and relative contents were determined using a normalized method. 56 peaks were obtained from extracts of spermoderm and 79 peaks from endosperm of T. chinensis var. mairei. Among these peaks, 37 chemical constituents were gained, and 24 compounds of which were identified (64.86%). There were 35 chemical constituents with content more than 1%, accounting for 94.59% of the total of all chemical constituents. 32 peaks were gained from petroleum ether extract, and 7 peaks were identified (21.88%) with content more than 1%. 36 peaks were gained from methanol extracts, and 14 peaks were identified (38.89%), 13 of which with content more than 1%, accounting for 92.86% of the total of all chemical constituents. 34 peaks were gained from ethyl acetate extracts, while 10 peaks were identified (29.41%) with content more than 1%. 33 peaks were gained from aether extracts, and 11 peaks were identified (33.33%). T. chinensis var. mairei seeds have various bio-active ingredients and a higher value for development and utilization as a medicinal plant.
