摘要
用GC-MS分析梅花(Prunus mume)5个品种(三轮玉蝶、北京玉蝶、单瓣玉、淡粉和江南朱砂)花朵中的挥发性成分,从中鉴定出45个化合物,其中芳香族化合物是主要成分。不同类型的梅花品种香气成分不同,这些化合物种类和含量的变化导致不同类型的梅花品种花香差异,一些重要的共有成分乙酸己酯、丁子香酚、乙酸苯甲酯和α-蒎烯等化合物的存在是导致梅花品种花香相似的主要原因。
Forty-five volatile constituents extracted from fresh flowers of five cultivars of Prunus mume,such as ＇Sanlun yudie＇,＇Beijing yudie＇,＇Danbanyu＇,＇Danfen＇ and ＇Jiangnan zhusha＇,were identified by headspace solid-phase microextraction（SPME） with a DVB-CAR-PDMS 50/30 μm fiber and gas chromatography-mass spectrometry（GC-MS）.The results showed that aromatic compounds were dominated in volatile constituents.The kind and content of compounds caused difference in flower fragrances of cultivars,but some important compounds,such as namely n-hexyl acetate,eugenol,benzyl acetate and α-pinene were common in all cultivars,which was the reason that the fragrance in all cultivars were similar.
