水蒸气蒸馏萃取法和同时蒸馏萃取法提取款冬花挥发油的比较

分别采用水蒸气蒸馏萃取法和同时蒸馏萃取法提取款冬花的挥发油,鉴定出其中的10种和20种化合物,占总峰面积的88.42%和82.03%,而其中相同的化学成分有7种,主要是β-红没药烯和7,10,13-十六三烯醛。同时蒸馏萃取法挥发油得率为1.936%,而水蒸气蒸馏萃取法挥发油得率为1.023%,说明同时蒸馏萃取法是款冬花挥发油可行的提取方法。

Comparisons o{ the Two Methods Between Steam Distillation Extraction and Simultaneous Distillation Extraction for Extracting the Volatile Oil from Tussilago farfara L.

There were 10 and 20 kinds of volatile oil extracted from tussilago farfara by the two methods of steam distillation extraction and simultaneous distillation extraction,respectively,accounting for 88.42% and 82.03% of total apices areas.Among these compounds,seven kinds of chemical components were same.The primary chemical components were β-bisabolene and 7,10,13-Hexadecatrienal.The volatile oil ratio of tussilago farfara extracted by simultaneous distillation extraction was 1.936%,while by the method of steam distillation extraction was 1.023%.So the way of simultaneous distillation extraction was feasible to extract volatile oil from Tussilago farfara L.
