龙眼微生物保鲜菌FJAT-0809-GLX发酵液丙酮萃取物的成分分析

GC/MS Analysis on Acetone Extracts from Microbial Fresh-Keeping Agent for Fruit longan

采用气相色谱质谱联用(GC/MS)的方法分析龙眼微生物保鲜菌FJAT-0809-GLX发酵液丙酮萃取物的成分,初步鉴定出化合物38种。在鉴定出的化合物中,匹配率在90%以上的成分有5种,包括2-呋喃甲醇、5-甲基呋喃醛、2-甲基-3-羟基-4-吡喃酮、1,4∶3,6-二脱水-α-吡喃葡萄糖、六氢吡咯并[1,2-a]吡嗪-1,4-二酮。相对含量较高的成分为六氢吡咯并[1,2-a]吡嗪-1,4-二酮和5-甲基呋喃醛,其相对含量分别达到了37.52%和4.97%。

Acetone extracts of mrcrobial Longan fresh-keeping agent were analyzed by GC-MS.Thirteen-eight compounds were identified.Five compounds with the match degree above 90%,including 2-Furanmethanol;2-Furancarboxaldehyde,5-methyl-;Malto;1,4∶3,6-Dianhydro-alpha-d-glucopyranose;Pyrrolopyrazine-1,4-dione,hexahydro-.The results showed that the main components were Pyrrolopyrazine-1,4-dione,hexahydro-and 2-Furancarboxaldehyde,5-methyl-,with relative amount of 37.52% and 4.97%.2-Furancarboxaldehyde,5-methyl-and Maltol were the aromatic compounds of Microbial Longan Fresh-keeping Angent.
