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.
