Extraction process of volatile oil from angelica dahurica leaves

The invention discloses an extraction process of volatile oil from angelica dahurica leaves and relates to the technical field of traditional Chinese medicine extraction processes. A steam distillation method and a solvent extraction method are utilized in the extraction process. According to the extraction process of the volatile oil from the angelica dahurica leaves, the angelica dahurica leavesare pulverized by using a pulverizer, so that the rate of extracting the volatile oil from angelica dahurica leaves by using the steam distillation method is increased; meanwhile, the angelica dahurica leaves becoming paste after being distillated can be rapidly taken out by arranging a placing net, so that the pasty angelica dahurica leaves are prevented from being bonded to the inner wall of asteam distillation device; residual water in an extractant is removed by utilizing anhydrous sodium sulfate, so that the quality of the volatile oil extracted from the angelica dahurica leaves by distillation is improved; due
