摘要:

以仔姜和老姜为原料,采用顶空固相微萃取-气相色谱-质谱联用法、以正癸烷为内标,分别对仔姜和老姜的挥发性成分进行分析。研究结果表明:从仔姜和老姜中共鉴定出89 种挥发性成分,其中仔姜中鉴定出63 种挥发性成分,主要包括37 种烃类、15 种醇类、6 种酯类、3 种醛类、2 种酮类,其主要挥发性成分为姜烯、橙花醇乙酸酯、β-雪松烯、α-法尼烯、(E)-柠檬醛、β-红没药烯;老姜中鉴定出68 种挥发性成分,主要包括45 种烃类、14 种醇类、3 种酯类、3 种醛类、3 种酮类,其主要挥发性成分为姜烯、α-姜黄烯、β-雪松烯、α-法尼烯、(E)-柠檬醛、β-红没药烯。

Abstract:

The volatile compounds in early and late harvested ginger (Zingiber officinale Roscoe) were analyzed by
headspace-solid phase micro-extraction (HS-SPME) combined with GC-MS using decane as an internal standard. A total of
89 volatile compounds were identified in ginger. There were 63 volatiles compounds in early harvested ginger (in August)
including 37 hydrocarbons, 15 alcohols, 6 esters, 3 aldehydes and 2 ketones, whereas there were 68 volatiles compounds in
late harvested ginger (in September of the same year) including 45 hydrocarbons, 14 alcohols, 3 esters, 3 aldehydes and 3
ketones. The major volatile compounds in early harvested ginger included zingiberene, neryl acetate, beta-cedrene, alphafarnesene,
trans-citral and beta-bisabolene, while those identified in late harvested ginger included zingiberene, alphacurcumene,
beta-cedrene, alpha-farnesene, trans-citral and beta-bisabolene.

Key words: ginger (zingiber officinale Roscoe), volatile compounds, headspace solid phase micro-extraction (HS-SPME), gas chromatography-mass spectrometry (GC-MS)
