旱金莲花挥发油的提取及卷烟加香

分别采用水蒸气蒸馏法和同时蒸馏萃取法提取旱金莲花挥发油,运用GC/MS分析挥发油的成分,根据内标法计算其含量,并进行卷烟加香试验.结果表明:水蒸气蒸馏法和同时蒸馏萃取法提取挥发油的得率分别为0.124%(1号)、0.517%(2号);检测到的化学组分分别为26、67种,其中有22种在2种方法提取的挥发油中均存在,主要是...

Comparative Study of the Two Methods for Extraction of Essential Oil fromTrollius Chinensis Bunge and Application of Tobacco Flavoring

The essential oil was extracted from Trollius chinensis Bunge by methods of steam distillation extraction and simultaneous distillation extraction respectively. The constituents of essential oil were isolated and identified by GCMS, the content of each component was calculated according to internal standard, and the essential oil obtained by the two different extraction methods were both applied in cigarette flavoring. The results showed that the yield ratio of essential oil from Trollius chinensis Bunge by steam distillation extraction was 0.124%( No.1),while by simultaneous distillation extraction 0.517% ( No.2).There were 26 kinds of compounds extracted by steam distillation extraction, and 67 kinds of compounds by simultaneous distillation extraction, among these compounds, 22 kinds of compounds were the same. The primary chemical components were higher fatty acids, higher alkanes, esters and alcohols, etc. Addition of 0.005 to 0.015 g essential oil obtained by steam distillation extraction or 0.005 to 0.010 g essential oil obtained by simultaneous distillation extraction to 100 g cigarette could augment and enhance the aroma and taste of smoking tobacco and reduce irritancy of the smoking cigarette, and essential oil extracted by simultaneous distillation could better improve the aroma property of tobacco. .
