摘要
在超临界CO2萃取压力为30 Mpa、萃取时间为3 h、萃取温度为50℃的静态条件下,分别萃取未做任何处理、无水乙醇处理、乙酸乙酯处理的黑胡椒原料中的油树脂,并利用气相色谱-质谱联用(GC-MS)对萃取得到的黑胡椒油树脂进行成分分析,同时利用保留指数和MS对物质进行定性分析。结果显示,在超临界萃取条件下,未做任何前处理的黑胡椒油树脂的香气成分有22种,采用无水乙醇进行前处理的黑胡椒油树脂的香气成分有17种,采用乙酸乙酯进行前处理的黑胡椒油树脂的香气成分有41种。
The operating conditions of the supercritical carbon dioxide process were 30 Mpa, 50℃and 3 h.Meanwhile, the gas chromatography-mass spectrometry（GC-MS） was used to analyze the composition of the oleoresin from the different pretreatments with ethanol, ethyl acetate or without pretreatment,respectively. The compounds identification of the black pepper oleoresin was based on the database and retention index for natural products. The amounts of oleoresin compounds were 22, 17 and 41 for without pretreatment, ethanol pretreatment and the ethyl acetate pretreatment.
