摘　　要：采用SPME-GC/MS方法分析槟榔花雄花和花梗中的香气成分。雄花中鉴定出47种香气成分,主要为乙酸异戊酯、苯乙烯、2-甲基丁酸-3-甲基丁酯、丙酸异戊酯、3,7-二甲基-2,6-辛二烯-2-甲基丁酸酯、乙酸己酯,其相对含量分别为:36.24%、8.44%、7.41%、5.62%、4.11%和3.93%;花梗中则鉴定出24种香气成分,主要为(Z)-3-己烯醇乙酸酯、(E)-3-己烯醇乙酸酯、乙酸己酯和乙酸异戊酯,其相对含量分别为:27.71%、26.51%、20.96%和11.97%。在槟榔花雄花和花梗中仅有6种共有香气成分,其相对含量分别占49.24%和60.35%。槟榔花雄花和花梗的香气均以酯类成分为主,但在其组成和含量上存在较大差异。The aromatic components in male flowers and stalks of areca inflorescence were determined and analyzed by SPME coupled with GC-MS. 47 kinds of aromatic components were identified in male flowers, mainly including 1-butanol, 3-methyl-, acetate, styrene, butanoie acid, 2-methyl-, 3-methylbutyl ester, 1-butanol, 3- methyl-, propanoate, butanoic acid, 2-methyl-, 3,7-dimethyl-2,6-octadineyl ester, and acetic acid, hexyl ester, of which relative contents was 36.24%, 8.44%, 7.41%, 5.62%0, 4.11% and 3.93%, respectively; while 24 kinds of aromatic components were identified in stalks, mainly including 3-hexen-l-ol, acetate, （Z）, 3-hexen-l-ol, acetate, （E）, acetic acid, hexyl ester, and 1-butanol, 3-methyl-, acetate, of which relative contents was 27.71%, 26.51%, 20.96% and 11.97%, respectively. There were only 6 kinds of common aromatic components between male flowers and stalks of areca inflorescence, and they accountied for 49.24% and 60.35% together. Ester compounds were the main aromatic compounds in male flowers and stalks of areea inflorescence, but their composition and content were significantly different.
