气相色谱质谱联用法分析滇姜花挥发油化学成分

 为了研究滇姜花挥发油的化学成分，本试验采用水蒸气蒸馏法从滇姜花的花中提取挥发油，用气相色谱-质谱联用仪对其进行分离测定，通过HPMSD化学工作站检索，对分离的化合物进行结构鉴定，应用色谱峰面积归一化法测定各成分的相对百分含量，鉴定出了29个化学成分。其中主要成分为(2E,6E)-3,7,11-三甲基-9-苯磺酰-2,6,10-十二烷基三烯-1-醇、(1R) (+)-α-蒎烯、莰烯、桧烯、乙酸1,7,7-三甲基二环［221］-2-庚酯、α-石竹烯、(E)-β-金合欢烯、2-茨醇，其含量分别为20636%，5913%，4128%，3964%，2046%，1786%，1737%，1568%。这些成分可能是滇姜花的主要释香成分。

Determination of Volatile Oil of Hedychium yunnanense Gagnep. by Gas Chromatography Mass Spectrography

To study chemical constituents from the flowers of Hedychium yunnanense Gagnep., the essential oil were obtained by steam distillation. The chemical constituents in essential oil were separated and identified by GC-MS and HPMSD Chemstation analysis, and their relative contents were determined by the method of area normalization. As a result, twenty nine compounds together with their contents were determined. Among them, (2E,6E) 3,7,11 trimethyl 9 (phenylsulfonyl) 2,6,10 dodecatrien 1 ol, (1R) (+) α pinene, camphene, sabenene, 1,7,7 trimethyl bicyclo［221］heptan 2 ol 2 acetate, α caryophyllen, (E) β farnesene and borneol were the major components. The contents of them were 20636%, 5913%, 4128%, 3964%, 2046%, 1786%, 1737%, 1568%, respectively. These compounds with relatively higher content might be the mainly characteristic aroma components of H. yunnanense.
