摘要
Abstract
Allium Mongoficum Regel was a kind of wild vegetable which distributed in desert regions with unique odor. HS-SPME-GC-MS was applied to identify the volatile compounds in Allium Mongoficum Regel based on three solid phase fibers of DVB/CAR/PDM,PDMS/DVB and PA. Results showed that 24 compounds were identified and DVB/CAR/PDMS was the optimal one to extract more compounds. 2-Hexenal content was 27.74% ,which was the most component,and other four compounds were Risulfide methyl 2-propenyl (25.70%), Dimethyl trisulfide ( 13.62% ), and Disulfide methyl 2-propeny (7.23%), Diallyl disulphide (7.23%), which totally represented 84.23% of the identified compounds,2-Hexenal was first reported in Allium Mongolicum Regel.关键词
