气-质联用法检测韭菜中香味成分的研究

Study on Flavor Compositions of Allium Tuberosum Rottler by GC/MS

运用GC/MS条件,研究了韭叶石油醚提取物及氯仿提取物的化学成分,共发现10种含硫化合物,其中4种化合物首次从该植物中找到。其中主要香味成分为甲基硫代亚磺酸甲酯,通过仿生合成和探讨其波谱性质验证了其结构。

Ten kinds of sulfur compounds were found in the leaves＇ extractives with petroleum benzing and chloroform by GC/MS . Four kinds of chemical compositions were first found in this plant. The primary flavor composition CH3SS（O） CH3 was bionicly synthesized ,and its struture was verified by studying its spectroscopic propertie.
