Abstract

The invention discloses a method for extracting effective component of angelica sinensis by a percolating technology, and belongs to the technical field of extraction of effective components of traditional Chinese medicinal materials. The method comprises the following steps: crushing; soaking; percolating for the first time; percolating for the second time; percolating for the third time; and collecting percolating liquid. According to the method, previous percolating liquid containing more effective components of the medicinal materials is used in the next preparation of a drug, and the restpercolating liquid containing fewer effective components of the medicinal materials is used as an extracting solvent of the traditional Chinese medicinal materials in a second percolating barrel in order to realize recycling; the percolating liquid which is previously collected and contains more effective components of the medicinal materials in the second percolating barrel is continuously usedin the next preparation of the drug; the rest percolating liquid is used in the extracting solvent of the traditional Chinese medicinal materials in a third percolating barrel, and the cyclic is repeated. Therefore, the extracting solvent is extremely utilized while the effective components of the medicinal materials are extracted to the maximum, and as a result, the solvent utilization rate is increased; the dose of the extracting solvent is decreased; and the cost of industrial production of angelica sinensis can be extremely reduced.

Description

technical field [0001] The invention belongs to the technical field of extracting effective components of Chinese medicinal materials, and in particular relates to a method for extracting effective components of angelica by percolation technology. Background technique [0002] Angelica sinensis Angelica sinensis ( Oliv. ) Dried root of Diels. It has the effects of nourishing blood and promoting blood circulation, regulating menstruation and relieving pain, and laxative. It is used for blood deficiency and chlorosis, dizziness and palpitations, irregular menstruation, amenorrhea and dysmenorrhea. According to the survey, commercially available concentrated angelica pills and liquid extracts of angelica are all extracted by percolation. Compared with the cold soaking method, the percolation method is the development of the cold soaking method, that is, it retains the advantages of the cold soaking method without heating, and retains the heat-sensitive components and volatil...
