摘　　要：该研究采用溶剂辅助蒸馏(solvent-assisted flavor evaporation,SAFE)技术和GC-MS深入探讨了劲酒中丰富的萜类化合物的组成、含量及其潜在价值。采用液液萃取结合SAFE提取劲酒的挥发性成分并除去不挥发性成分,提取液浓缩后经GC-MS分析,实验优化了液液萃取和SAFE条件。通过谱库检索与保留指数对比,从劲酒中鉴定出71种萜类化合物,其中单萜类29种,倍半萜42种。通过定量分析,发现劲酒中主要的萜类化合物为乙酸龙脑酯[(17222.4±335.2)μg/L]和樟脑[(10920.8±225.1)μg/L],都属于单萜化合物,呈清爽松木香气,具有杀菌、抗炎、止痛功效。劲酒中倍半萜类种类丰富,结构复杂,其含氧衍生物大多有较强的生物活性,其中含量较高的倍半萜菖蒲烯[(237.09±6.11)μg/L]和α-杜松醇[(236.2±20.3)μg/L]具有抗癌潜力,α-白菖考烯[(172.49±3.71)μg/L]也具有清热平喘的功效。这些化合物对形成劲酒独特的风味与功能具有重要贡献,为劲酒中功能因子的研究提供了新的思路和方向。This study investigated the composition,content,and potential value of diverse terpenoids in Jingjiu based on solvent-assisted flavor evaporation(SAFE)and GC-MS techniques.Volatile components of Jingjiu were extracted and non-volatile components were removed using liquid-liquid extraction combined with SAFE.The concentrated extracts were then subjected to GC-MS analysis.The experimental conditions for liquid-liquid extraction and SAFE were optimized.By utilizing spectral library retrieval and retention index comparisons,a total of 71 terpenoid compounds were identified in Jingjiu,including 29 monoterpenes and 42 sesquiterpenes.Quantitative analysis revealed that the predominant terpenoid compounds in Jingjiu were the monoterpenes,including bornyl acetate[(17222.4±335.2)μg/L]and(+)-2-bornanone[(10920.8±225.1)μg/L].Both of these compounds imparted a refreshing pine aroma and possess antimicrobial,anti-inflammatory,and analgesic properties.The sesquiterpenes exhibited structural complexity and many of their oxygenated derivatives demonstrated significant biological activity.Among them,the sesquiterpenes calamenene[(237.09±6.11)μg/L]andα-cadinol[(236.2±20.3)μg/L]showed potential anti-cancer properties,whileα-calacorene[(172.49±3.71)μg/L]exhibited anti-inflammatory and bronchodilatory effects.These compounds significantly contribute to the distinctive flavor and functionality of Jingjiu,offering novel insights and directions for the study of functional factors in Jingjiu.
