摘要: 本论文采用Box-Behnken响应曲面设计法,优化超临界CO2萃取松茸精油的工艺,并采用GC-MS分析该松茸精油的化学成分。优化的最佳工艺为:萃取压力32.46 MPa,萃取46.01 ℃,89.15%的乙醇作为夹带剂。同时,GC-MS的分析结果显示松茸精油的主要成分为9,12-十八碳二烯酸、麦角固醇和9,12-十八碳二烯酸甘油酯。其中,9,12-十八碳二烯酸和麦角固醇为松茸精油中抑制黑素合成的主要成分。

Abstract: In this study,a supercritical carbon dioxide extraction method was employed to extract the essential oil from Tricholoma matsutake. The extraction conditions were optimized by response surface methodology (RSM).Furthermore,the chemical composition of the essential oil was analyzed by gas chromatographymass spectrometry (GC-MS).The optimal conditions to obtain the highest yield of essential oil were determined as:32.46 MPa pressure,46.01 ℃ temperature and 89.15 vol.% ethanol.Furthermore,9,12-octadecadienoic acid,ergosterol and 2,3-dihydroxypropyl 9,12-octadecadienoate were the major constituents presented in T.matsutake.  Among them,9,12-octadecadienoic acid and ergosterol can inhibit melanin synthesis.

Key words: Tricholoma matsutake, essential oil, supercritical fluid extraction, response surface methodology, chemical analysis
