利用顶空固相微萃取/气相色谱/质谱(HS/SPME/GC/MS)联用技术对凤丹白和凤丹粉两种鲜花的挥发性成分进行研究,比较分析两种凤丹鲜花挥发性成分。两种凤丹鲜花中共检测出50种挥发性成分,其共有的挥发性成分有27种。在凤丹白鲜花中检测出41种挥发性成分,占挥发性总成分的89.00%,主要为碳氢类、醛类、醚类、醇类、酚类和酯类化合物,分别占挥发性总成分的55.78%、21.15%、9.22%、2.32%、0.27%和0.26%;在凤丹粉鲜花中检测出36种挥发性成分,占挥发性总成分的89.00%,主要为碳氢类、醚类、醇类、醛类、酯类和酚类化合物,分别占挥发性总成分的78.76%、4.07%、2.72%、2.70%、0.42%和0.33%。两种凤丹鲜花挥发性成分及含量差异比较显著,差异性成分主要表现为:凤丹白含有(R)-3,7-二甲基-6-辛烯醛、壬醛、正己醛、2,2,4,6,6-五甲基-庚烷等,而凤丹粉含有6,9-十七烷二烯。
The volatile components of two fresh flowers of Fengdanbai and Fengdan powder were studied by headspace solid-phase microextraction / gas chromatography / mass spectrometry (HS / SPME / GC / MS) Sexual ingredients. Fifty kinds of volatile components were detected in two kinds of flowers, with 27 kinds of common volatile components. 41 volatile components were detected in the fresh flowers of Fengdan, accounting for 89.00% of the total volatile components, mainly hydrocarbons, aldehydes, ethers, alcohols, phenols and esters, which accounted for volatile The results showed that 36 kinds of volatile components were detected in the Fengdan powder flowers, accounting for 89.00% of the total volatile components, mainly hydrocarbons, ethers Alcohols, aldehydes, esters and phenolic compounds accounted for 78.76%, 4.07%, 2.72%, 2.70%, 0.42% and 0.33% of the total volatile components, respectively. The volatile constituents and contents of two species of Pseudostellariae Radix were significantly different. The main components of the differences were as follows: (1) The content of (R) -3,7-dimethyl-6-octenal, nonanal, , 2,4,6,6-pentamethyl-heptane and the like, while phoenixes powder contains 6,9-heptadecadiene.
