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。

摘  要:
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.
