摘要: 采用顶空-气质联用法检测水蒸气蒸馏提取的栀子鲜花精油中的挥发性成分，为开发利用栀子鲜花精油提供科学依据。从栀子鲜花精油中分离鉴定出150种挥发性成分，挥发性成分的相对总含量为99.56%，主要含萜烯类、酯类、醇类、酮类、芳香族类等成分。其中以萜烯类成分的数量最多，达48种，相对含量最高，达38.89%；相对含量较高的挥发性成分有罗勒烯、芳樟醇、惕各酸叶醇酯、惕各酸己酯、2-甲基-1-丁基惕各酸酯，相对含量分别为19.68%、17.70%、10.12%、7.27%、6.01%。栀子鲜花精油香气充足、香味优雅独特，含有醇类、醛类、萜烯类等多种活性成分，具有抗菌、抗炎、抗肿瘤、抗焦虑等功效。

Abstract: The method of headspace-gas chromatography-mass spectrometry was used to detect the volatile components in the essential oil of Gardenia jasminoides fresh flower extracted by the steam distillation, in order to provide scientific basis for the development and utilization of the essential oil in the fresh flower of Gardenia jasminoides. 150 volatile components were isolated and identified from the essential oil of Gardenia jasminoides fresh flower. The relative total content of volatile components was 99.56%. The main components included terpenes, esters, alcohols, ketones, aromatics and so on. Among them, the number of terpenes was the highest, reaching 48 kinds, as well as the relative content was the highest (up to 38.89%). The volatile components with higher relative content were ocimene, linalool, (Z)-hex-3-enyl (E)-2-methylbut-2-enoate, hexyl tiglate and 2-methyl-1-butyl tiglate, with relative contents of 19.68%, 17.70%, 10.12%, 7.27% and 6.01%, respectively. The essential oil of Gardenia jasminoides fresh flower had abundant aroma, elegant and unique fragrance. Due to the existence of the active constituents such as alcohols, aldehydes, terpenes and so on, the essential oil of Gardenia jasminoides fresh flower possessed the antibacterial, anti-inflammatory, antineoplastic, and antianxiety properties.
