摘  要:
姜花是姜科姜花属多年生草本植物,不同种的姜花在香气上存在很大差异。对姜花挥发性香气物质组成的研究,有助于了解其生物合成的可能途径,为进一步研究其香气代谢打下基础。本试验用固相微萃取—气相色谱质谱分析法对香气释放量有差异的4种姜花进行香气成分和含量的测定。结果显示:4种不同颜色姜花的释香成分和含量都有显著性差异,其中,红姜花的挥发性成分相对含量仅为1.21μg.h-1.g-1FM,而金姜花、黄姜花、白姜花分别为16.80、13.64、17.36μg.h-1.g-1FM;使姜花产生浓郁香气的主要成分可能是沉香醇和1,8-桉油醇等萜烯醇类化合物。

摘  要:
Hedychium is a perennial herbaceous genus belonging to Zingiberaceae.Aroma production differs among different Hedychium species.Studies on the aroma components will help us with the understanding of their biosynthesis and with the breeding of new varieties via bioengineering.In this study,gas chromatography-mass spectrometry combined with solid-phase microextraction(SPME-GC-MS)was developed for the determination of aroma components in four different Hedychiums species,namly H.coccineum,H.gardnerianum,H.flavum and H.coronarium,which have different fragrance.The results showed that the aroma components and contents in the four Hedychiums species were different.The relative aroma content in H.coccineum was only 1.21 μg·h-1·g-1FM,but that in H.gardnerianum,H.flavum and H.coronarium were 16.80,13.64 and 17.36 μg·h-1·g-1FM,respectively.L-linalool and 1,8-cineole might be the characteristic aroma components in Hedychium.
