摘 要:本论文研究了硫磺熏未水洗参,硫磺熏水洗参,未经硫磺熏未经水洗参以及未经硫磺熏经水洗参的挥发性物质的差异。目的在于检测经硫磺熏制的参中是否含有对人体有害的含硫化合物以及硫磺熏制后的参经水洗后能否去除含硫化合物。利用同时蒸馏萃取的方法从参中提取挥发性物质。进一步利用气质联用法进行成分测定分析。结果表明,硫磺熏未水洗参的挥发油中含有2种含硫化合物,硫磺熏经水洗参的挥发油中没有含硫化合物。硫磺熏制后的参产生了对人体有害的含硫化合物,硫磺熏参经水洗之后可以完全去除其挥发油中的含硫化合物。59319

Abstract:This paper studies the sulfur smoked washing codonopsis pilosula,sulfur smoked without washing codonopsis pilosula,without the sulfur smoked without washing codonopsis pilosula and without sulfur smoked but washed codonopsis pilosula of the volatile substances of codonopsis pilosula extract differences.Purpose is to detect whether the sulfur smoked codonopsis pilosula containing sulfur compounds that are harmful to human body and the sulfur smoked codonopsis pilosula after washing whether to remove sulfur compounds.Volatile substances was extracted by the simultaneous distillation extraction (SDE).The chemical components were detected by means of GC-MS.The results showed that volatile oil of sulfur smoked not washed codonopsis pilosula contains two kinds of sulfur compounds, volatile oil of the sulfur smoked washing codonopsis pilosula do not contain sulfur compounds. Sulfur smoked codonopsis pilosula emerges sulfur compounds which is harmful to human body and sulfur smoked codonopsis pilosula by washing can remove sulfur compounds.
Keywords:simultaneous distillation extraction,GC-MS,codonopsis pilosula

我国中草药生产历史悠久。在很久之前,我们祖先就用中草药治病,不同的中草药有不同的功效,参就是中草药的一种。参,又名黄参、上人参、防参,多年生草本植物。主要分布于东北、华北及陕西、宁夏、甘肃、青海、河南、四川、云南、西藏等与沙漠接壤的典型大漠干旱或戈壁滩上[1-2]。参根略呈圆柱形、纺锤状圆柱形或长圆锥形,少分枝,长15-30cm,直径0.4-2cm。表面灰黄色至棕灰色,有不规则沟壑,疏生横长皮孔,上部分多环状皱纹,根头附近最密。根头有很多突起的茎痕和芽痕,呈现球状,一般被称为“狮子盘头芦”。质柔软或坚实,断面较平整,有的呈角质样,皮部较厚,黄白色至棕色,一般有缝隙,与木部交接的地方有深棕色的环,木部大约占根直径的1/3-1/2,淡黄色,有淡淡香,甜,嚼起来没有渣[3]。参具有健脾益肺,补中益气,和胃生津等功效。可以治疗脾肺虚弱、心悸气短、食少便溏、虚喘咳嗽、内热消渴等症状,是我国传统的补益药,被称为人参的替代品[4]。
