摘要: 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、六氢吡咯并吡嗪-1,4-二酮。相对含量较高的成分为六氢吡咯并吡嗪-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%。

Abstract: 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.
