摘要
为探讨人参地下部位的挥发性成分(VOCs)的差异及炮制方法对人参地下部位挥发性成分的影响,本文采用顶空固相微萃取(HS-SPME)与气相色谱-质谱(GC-MS)相结合的分析方法检测生晒参和红参的主根、须根和参芦挥发性成分。结果表明,从样品中鉴定出34种成分, β-人参烯、α-甘香烯、β-石竹烯、 β-榄香烯、β-古芸烯、β-合金欢烯、香树烯、α-芹子烯及斯巴醇是生晒参和红参根须芦各部位共有的特征成分。各部位挥发性成分的组成相同,均是由倍半萜烃、倍半萜醇和烷烃组成。与生晒参的低温干燥相比,红参经过高温加热处理后各部位倍半萜烯含量明显升高,而倍半萜烯醇含量显著降低,但是倍半萜类总量只比生晒参稍高,差异不显著。
To interpret volatile compounds(VOCs) in underground parts of ginseng and processing techonologies on VOCs. The headspace solidphase microextraction(HS-SPME) and gas chromatography mass spectrometry(GC-MS) were applied to detect VOCs in taproot, fibrousroot and rhizome.The results showed that thirty four VOCs were identified,β-panasinsene,α-elixene,β-Caryophyllene,β-elemene,β-gurjunene,(E)-β-famesene, alloaromadendrene,α-selinene, and spathulenol were the common characteristic compounds in all samples.Composition of VOCs were composed of sesquiterpene hydrocarbon, sesquiterpene alcohol and alkane. The content of sesquiterpene hydrocarbon increased and sesquiterpene alcohol decreased significantly in different underground parts of red ginseng after high temperature heating, VOCs changing was completely opposite in the dried raw ginseng, but the total amount of sesquiterpene was slightly higher than that of raw ginseng, and the difference was not significant.
