[GC-MS analysis of volatile aromatic substances in Chaenomeles speciosa fruit].

ABSTRACT

OBJECTIVE: To analyze the volatile aromatic substances in Chaenomeles speciosa fruit produced in Chongqing in order to provide the characteristic data for it's resources development and flavors chemistry research. METHODS: The volatile aromatic substances were extracted by steam distillation from Chaenomeles speciosa fresh fruit and seperated and identified by GC-MS. RESULTS: 106 volatile aromatic substances were seperated and identified, mainly including esters, alcohols, carboxylic acids, alkanes and alkenes, ketones, which made a great contribution to flavor of Chaenomeles speciosa fresh fruit. CONCLUSION: This study elucidated the composition of volatile aromatic substances in Chaenomeles speciosa fruit produced in Chongqing, which could provide basic information for exploitation and utilization of it's flavor substances.
