不同类型梅花品种挥发性成分的研究

Studies on the Volatile Constituents from Cultivars of Prunus mume

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。

Abstract:

Forty-five volatile constituents extracted from fresh flowers of five cultivars of Prunus mume, such as ‘Sanlun yudie’, ‘Beijing yudie’, ‘Danbaiyu’, ‘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.
