摘要: 为分析乌梅中挥发性成分的组成,采用同时蒸馏萃取(simultaneous distillation extraction,SDE)提取,气相色谱-质谱联用(gas chromatography-mass spectrometry,GC-MS)对乌梅中挥发性成分进行分析。从乌梅提取物中共鉴定出47种成分,主要包括酚类12种、酸类10种、酯类7种、杂环化合物6种、酮类4种、醛类4种和醇类2种等,其中糠醛(44.09%)、乙醇(12.71%)、苯甲醛(11.31%)、乙酸(7.33%)、十六酸(6.65%)、5-甲基糠醛(3.34%)、苯甲醇(2.04%)、乙酸乙酯(1.41%)和丁香酚(1.11%)。通过4次平行GC-MS分析,验证了定性定量结果的可靠性。

Abstract: The volatile compounds of Fructus Mume were extracted by simultaneous distillation-extraction (SDE) and analyzed by GC-MS. Forty-seven volatile compounds were identified including 12 phenols, 10 acids, 7 esters, 6 herterocylic compounds, 4 ketones, 4 acetals and 2 alcohols. Among these compounds, furfural (44.09%), ethanol (12.71%), benzaldehyde (11.31%), acetic acid (7.33%), n-hexadecanoic acid (6.65%), 5-methylfurfural (3.34%), benzyl alcohol (2.04%), ethyl acetate (1.41%) and eugenol (1.11%) were predominant. The qualitative and quantitative results obtained by the method were reliable, as validated by 4 parallel experiments.

Key words: Fructus Mume, simultaneous distillation extraction, GC-MS, analysis
