为了观察福州茉莉花源质量的稳定性，曾时其精油成分作过连续三年的成分研究￣［１］。本文继续对净油和头香成分作进一步探讨。本实验室用溶剂提取和用冷乙醇分离花蜡来获得净油．用低温吸附和溶剂洗脱获得头香样品。采用石英毛细管气相色谱（ＣＧＣ）和色谱－质谱（ＣＧＣ－ＭＳ）对成分进行剖析。实验结果对福州茉莉花源质量随气候变化的规律￣［１］作了进一步地确认。
In order to observe the stability of the quality of Fuzhou jasmine flower source, the composition of the essential oil component has been studied for three years in a row [1]. This article continues on the net oil and head fragrance ingredients for further discussion. The laboratory used solvent extraction and isolation of wax flowers with cold ethanol to obtain absolute oil. Aroma samples were obtained by cryogenic adsorption and solvent elution. The constituents were analyzed by quartz capillary gas chromatography (CGC) and mass spectrometry (CGC-MS). The experimental results on Fuzhou jasmine source quality with the law of climate change ~ [1] made further confirmation.
