金莲花挥发油成分分析及其在单料烟加香中的应用

Analysis of the Essentlal Oil from Trollius Chinensis Bunge and its Application in Unblended Cigarette Flavoring

摘要:

分别采用水蒸气蒸馏、同时蒸馏萃取、超声、闪式、先超声后同时蒸馏萃取，先闪式后同时蒸馏萃取6种提取方法提取金莲花挥发油，运用GC-MS分析挥发油的成分，并进行单料烟加香试验。结果表明：①金莲花挥发油得率分别为0.20%、0.67%、2.31%、2.67%、0.82%、0.78%，分别鉴定出20、30、19、18、37、30种成分；其中β紫罗兰酮、二氢猕猴桃内酯等为主要的香气成分；超声和闪式提取方法虽然挥发油得率高，但是杂质也较多，先超声后同时蒸馏萃取的挥发油优于其他几种。②在烟丝中，添加适量金莲花挥发油，能提高卷烟烟气的香气质和香气量，降低刺激性，改善余味，先超声后同时蒸馏萃取的挥发油加香效果最好。

Abstract:

The essential oil was extracted from Trollius chinensis Bunge by steam distillation extraction, simultaneous distillation extraction, ultrasonic extraction, homogenate extraction simultaneous distillation extraction followed ultrasonic extraction, simultaneous distillation extraction followed homogenate extraction methods. The constituents of essential oil were isolated and identified by GC-MS, and the applications of the oil in unblended cigarette flavoring were studied as well. The results showed that: 1) The extraction rate of oil extracted by the six methods was 0.20%, 0.67%, 2.31%, 2.67%, 0.82%, 0.78% and 20, 30, 19, 18, 37, 30 compounds were identified, respectively; the primary chemical components were β-ionone and dihydroactinidiolide, etc; among of them, the total amount of essential extracted by ultrasonic extraction, homogenate extraction are higher relatively, but they more impurity, the oil extracted by simultaneous distillation extraction followed ultrasonic extraction is better than the others. 2) It could play an important role in enhancing the aroma quality of cigarette, obviously reducing the irritation, and smoothing the smoke while essential oil of simultaneous distillation extraction followed ultrasonic extraction is better than the others.
