裂解气相色谱-质谱联用法对桔梗浸膏的热裂解产物分析
Pyrolysis-Gas Chromatographic Analysis of Balloonflower Root Extract for Its Pyrolytic Products
摘 要
采用在线热裂解气相色谱-质谱法(Py-GC-MS)法研究了桔梗浸膏热裂解性质.在氦气氛围中,将桔梗浸膏分别在不同温度下进行热裂解,并以气相色谱-质谱法(GC-MS)对其裂解产物进行定性和半定量分析,并用桔梗浸膏进行了卷烟加香试验.结果表明:桔梗浸膏在300,450,600,750,900 ℃裂解温度下检测到的挥发性热裂解产物分别达20种、33种、48种、46种和46种;桔梗浸膏具有改善和修饰卷烟吸味、丰满烟气、减轻刺激性的作用.桔梗浸膏添加到卷烟中能明显的提高卷烟抽吸品质.

Abstract
The pyrolytic properties of balloonflower root extract were studied by the hyphenation of on-line pyrolysis,gas chromatography and mass spectrometry (Py-GC-MS).In an helium atmosphere,the extract was pyrolyzed at 300,450,600,750,and 900 ℃,separately.The pyrolytic products were directly introduced into the instrument and analyzed qualitatively and semi-quantitatively.The extract was added into cigarettes as a flavor.The results showed that: 1) there are 20 kinds of pyrolyzates at 300 ℃,33 kinds at 450 ℃,48 kinds at 600 ℃,46 kinds at 750 ℃ and 46 kinds at 900 ℃;2) the balloonflower root extract as an additive to cigarettes improved and modified the flavor of cigarette smoking,enhanced the notes of fresh aroma,and reduced its irritation.The extract of balloonflower root was added to cigarettes to improve its smoking character.
