【摘要】：分別采用同時(shí)蒸餾萃取法(SDE)和頂空固相微萃取法(HS-SPME)提取香榧假種皮的揮發(fā)性物質(zhì),并用氣相色譜-質(zhì)譜法(GC-MS)結(jié)合峰面積進(jìn)行定量分析,結(jié)合保留指數(shù)進(jìn)行定性分析。結(jié)果表明,2種萃取方法一共檢出匹配度達(dá)90%以上的揮發(fā)性物質(zhì)成分96種,其中SDE法鑒定出57種,HS-SPME法鑒定出了39種。被檢測(cè)出的物質(zhì)中,烯烴類最多,達(dá)60種,其次是醇類12種、羧酸和酯類9種,醛酮類3種,其他類型化合物12種。對(duì)2種方法各揮發(fā)性成分進(jìn)行分析,結(jié)果顯示,采用HS-SPME方法的前處理簡(jiǎn)單、分析時(shí)間短且重復(fù)性好,適于香榧揮發(fā)性成分的快速測(cè)定。而將這2種方法綜合使用,則能更全面地反映香榧假種皮精油揮發(fā)性物質(zhì)的成分。
[Abstract]:Using simultaneous distillation and extraction (SDE) and headspace solid phase microextraction (HS-SPME) extraction of volatile substances of Torreya grandis aril, and by gas chromatography-mass spectrometry (GC-MS) quantitative analysis combined with the peak area, combined with retention index for qualitative analysis. The results showed that 2 kinds of extraction methods, detected a total of volatile more than 90% of the 96 components, the SDE identified 57, HS-SPME identified 39. Detected substances in alkenes the most, up to 60 species, followed by 12 kinds of alcohols, carboxylic acids and 9 kinds of esters, 3 aldehydes and ketones, other types of 12 compounds. The volatile components of 2 kinds of methods of analysis, the results showed that pretreatment with HS-SPME method is simple, short analysis time and good repeatability, suitable for rapid determination of volatile components. The Torreya these 2 kinds of methods are used, it can comprehensively reflect the essential oil of Torreya grandis aril The composition of a hair substance.
