【摘要】 用改进的循环吹气吸附法捕集树兰干花的头香,溶剂洗脱后用GC/MS分析,在两种毛细管色谱柱上(OV-101,PEG-20M)利用质谱和程序升温保留指数鉴定化合物。共鉴定了54种成分,其中29种化合物是已报道的树兰花精油、净油成分中所没有的。更多还原

【Abstract】 The headspace volatiles of the dry flowers of Aglaia odorata were trapped by a modified circulating adsorption method and were analyzed by GC/MS techniques after desorption by solvent.The components were identified by mass spectral and temperature -programmed retention index data on two types of glass capillary columns (OV-101 and PEG-20M).54 compounds have been identified from the volatiles,including 21 sesqui-terpenes, 8 aldehydes,7 alkyl benzenes,6 alkanes,6 other oxygen-containing compounds and 1 nitrogen containing compound.29 compounds have not been reported in the studies on the constituents of the essential oil or absolute oil of the flowers.更多还原
