黄芩根提取物的制备及其在烟草香气中的作用研究

Study on the Preparation of Scutellaria baicalensis Root Extract and its Effect in Tobacco Flavor

以黄芩苷为目标制备了黄芩提取物,分析其有效成分并研究了烟用效果。采用裂解气相色谱-质谱联用(PyGC-MS)法,模拟卷烟典型燃烧环境,研究了黄芩苷在不同气氛中的裂解产物,探讨其在卷烟中的致香机理。结果表明,所制备的黄芩提取物含有22.11%的黄芩苷,在卷烟中的作用为增加香气、柔和烟气、改善余味。裂解试验发现,黄芩苷在不同温度和不同环境中发生裂解,生成烃类、酮类、醛类、呋喃类及其衍生物等致香成分,含量最高的为糠醛和苯乙酮。不同温度和不同气氛条件下裂解,产物及含量均有差别。以上结果表明,黄芩提取物可作为潜在的烟用香料。

Scutellaria baicalensis Georgi root extract was prepared,its baicalin content and smoking effect were analyzed.Under typical conditions of burning cigarette,pyrolysis contents of baicalin were investigated by pyrolysis-gas chromatography-mass spectrometry（PyGC-MS）.The results show that S.baicallensis root extract contains 22.11% baicalin;in tobacco,it can increase flavor,soften smoking,improve after-taste.Under different conditons,baicalin pyrolysed to flavor substances,such as alkanes,ketones,aldehydes,furans and their derivatives;furfural and acetophenone were the main components.The pyrolysis products and contents were changed with different atmosphere and temperature.These results indicated that S.baicallensis extract could be a potential tobacco flavor.
