摘要: 利用超快速气相色谱电子鼻(gas chromatography-based electronic nose,GC-E-nose)技术快速鉴定调味香料荜茇精油(essential oil from Piper longum L.,EOPL)的化学成分,并通过GC-E-nose结合化学法,在未经单体分离的条件下,对EOPL中的化学成分清除1,1-二苯基-2-三硝基苯肼(1,1-dipheny1-2-picrylhydrazyl,DPPH)自由基、2,2’-联氮-双-(3-乙基苯并噻唑啉-6-磺酸)二铵盐(2,2’-azinobis-(3-ethylbenzthiazoline-6-sulphonate),ABTS)阳离子自由基和羟自由基活性进行评价。结果表明,EOPL的主要成分为大根香叶烯(26.04%)、石竹烯(13.57%)、顺式-茴香脑(8.87%)和β-甜没药烯(7.32%)。EOPL各组分清除自由基的活性有很大差异,在所有精油成分中顺式-茴香脑、氧化石竹烯和右旋萜二烯对DPPH自由基、ABTS阳离子自由基和羟自由基具有最强的清除活性,清除率分别达到78.1%、87.0%和71.6%。为了验证GC-E-nose对精油成分鉴定的可行性,同时采用气相色谱-质谱联用技术对EOPL的化学成分进行分析,符合度高达89.7%。

Abstract: In the present work, the chemical components of the essential oil from Piper longum L. (EOPL) were quickly identified with an ultra-fast gas chromatography-based electronic nose (GC-E-nose). The scavenging activities of each component of EOPL against 1,1-dipheny1-2-picrylhydrazyl (DPPH) radicals, 2,2’-azinobis-(3-ethylbenzthiazoline-6-sulphonate) (ABTS) cation radicals, and hydroxyl radicals were evaluated by GC-E-nose combined with chemical methods without time-consuming and laborious separation of the monomers. The results showed that the main components of EOPL identified by GC-E-nose were germacrene D (26.04%), caryophyllene (13.57%), cis-anetholel (8.87%), and β-bisabolene (7.32%). Among all identified components, cis-anethol, caryophyllene oxide, and D-limonene had the strongest scavenging capacity against DPPH radicals, ABTS cation radicals, and hydroxyl radicals, with scavenging percentages of 78.1%, 87.0%, and 71.6%, respectively. The results of GC-E-nose for essential oil components were 89.7% consisted with those of gas chromatography-mass chromatography (GC-MS), confirming the feasibility of GC-E-nose.

Key words: essential oil from Piper longum L.; ultra-fast gas chromatography-based electronic nose; gas chromatography-mass spectrometry; quick screening; radical scavenging activity
