摘 要 ：采用无水乙醚超声萃取得到新鲜木荷(Schima superba)花浸膏提取物，顶空固相微萃取富集挥发性成分，气相色谱-质谱联用仪分析，归一化法计算各组分的相对含量。鉴定出挥发性化合物中的51个成分, 约占相对总含量的99%；挥发性成分中含氧化合物的含量超过93%，其中主要的化合物及其相对含量为酮代异佛尔酮(26.33%)、氧化芳樟醇(19.53%)、环氧芳樟醇(8.80%)、3,7-二甲基-2,6-辛二烯-1-醇(8.23%)、白藜芦素(7.89%)、4-羟基-3,5,5-三甲基-2-环己烯-1-酮(6.54%)、2,6,6-三甲基-1,4-环己二酮(4.06%)、苯乙醇(2.17%)、2-甲基-2-壬烯-1-醇(2.04%)等。

Abstract:Volatile components were extracted from Schima superba flowers by sonication with anhydrous ether, and analyzed by gas chromatography-mass spectrometry (GC-MS) with headspace solid phase micro-extraction (HS-SPME). Fifty-one components were identified, accounting for 99% of the volatile components. The content of oxygenated compounds were more than 93% in the volatile components. The main components included 4-oxoisophorone (26.33%), linalool oxide (19.53%), epoxylinalol (8.80%) 3,7-dimethyl-2,6-octadien-1-ol (8.23%), veratrol (7.89%), 4-hydroxy-3,5,5-trimethyl-2-cyclohexen-1-one (6.54%), 2,6,6-trimethyl-1,4-cyclohexanedione (4.06 %), phenylethyl alcohol (2.17%), 2-methyl-2-nonen-1-ol (2.04%), etc.
