广西灵香草提取物的化学成分研究及香气评价

目的 :研究广西金秀灵香草提取物的化学成分及香气。方法 :采用超临界CO2 萃取法和溶剂法提取的广西灵香草提取物 ,用气相色谱 /质谱进行分离测定 ,结合计算机检索技术对分离的化合物进行结构鉴定 ,应用色谱峰归一化法确定各成分的相对含量。结果 :超临界CO2 萃取灵香草提取物得率 1.5 % ,鉴定出 2 7个化学成分 ,溶剂法得率 1.2 % ,鉴定出 2 0个化学成分 ;经评定 ,超临界CO2 萃取法得到的提取物气味更接近灵香草天然香气。结论 :用超临界CO2 萃取法可以生产出最接近自然香气的天然香料

Chemical Components Study and Odor Evaluation of Extract of Strongfragrant Leosestrife (Lysimachia foenum-graecum Hance)

Purpose: Study chemical components and odor of extract of Lysimachia foenum-graecum Hance in this paper. Method: Guangxi Lysimachia foenum-graecum Hance was extracted by supercritical CO 2 extraction and orga~nic solvent extraction, the extract was separated and detected by GC /MS, and its components were identified by compu~ter index technology, The components relative content were determined by area nomalization. Result: yield of extract of Lysimachia foenum-graecum Hance by supercritical CO 2 extraction is 1.5%, 27 chemical components were identified, yield of solvent extraction is 1.2%,and 20 chemical components were identified; the odor of the extract prepared by supercritical CO 2 extraction is very near to that of natural Lysimachia foenum-graecum Hance. Conclusion: Supercritical CO 2 extraction can produce the product, the odor of which is the most similar to that of Srongfragrant Leosestrife.
