GC-MS分析甜菊叶的挥发性成分

GC-MS Analysis of Volatile Components in Leaves of Stevia rebaudianum

摘要:

甜菊(Stevia rebaudianum Bertohi)叶经固相微萃取(SPME)和同时蒸馏萃取(SDE)，用气相色谱/质谱法(GC-MS)检测其挥发性成分。从甜菊叶中共检出101种化学物质，其中从SPME萃取物中检出67种，SDE萃取物中检出80 种，二者共有组分46种。主要成分为反式-α-香柠檬烯、β-蒎烯、石竹烯氧化物、匙叶桉油烯醇、橙花叔醇等，其主要成分与菊科(Compositae)其他植物的明显不同。

Abstract:

The volatile components extrected from leaves of Stevia rebaudianum Bertohi were studied using by Solid phase micro-extraction (SPME) and Simultaneous distillation extraction (SDE), and chemical constituents were analyzed by gas chromatograph/mass spectrometer (GC-MS). One hundred and one compounds were identified, in which there were sixty-seven compounds from SPME, eighty from SDE, among them forty-six from both SDE and SPME. The main compositions were trans-β-farnesene, β-pinene, caryophyllene oxide, spathulenol, nerolidol, which were much different from other Compositae plant.
