Method for extracting lily colchicines with assisting of micro-cutting interaction technology

Abstract

The invention discloses a method for extracting lily colchicines with assisting of a micro-cutting interaction technology. The method comprises the steps that firstly, lilies are washed cleanly, dried and smashed to obtain lily powder; next, the lily powder and sodium carbonate are mixed and ground to obtain mixed micro powder; then, the mixed micro powder is put into a single-stage type continuous countercurrent ultrasonic extracting machine to be subjected to ethanol extraction; finally, reduced pressure distillation and drying are carried out on extracted filtrate, and the lily colchicines are obtained. Compared with the prior art, the method has the advantages that the micro-cutting interaction technology is adopted to assist lily colchicine extraction, in an ultramicro-pulverised powder state, the solubility of the colchicines in an ethanol solution can be effectively improved, and the exhalation rate of the cochicines is further improved; in the colchine ethanol extraction process, under the effect of ultrasonic waves, the continuous countercurrent extraction technology is adopted in an auxiliary mode, the permeation dissolution and diffusion speed in the colchicine extraction process can be accelerated, the extraction time is shortened, the usage amount of a solvent can be reduced, and the colchicine extraction method is high in efficiency and low in consumption.

Description

technical field [0001] The invention belongs to the technical field of extraction of plant effective components, and in particular relates to a method for assisting the extraction of narcissin from lily flowers by using a micro-cutting aided interaction technique. Background technique [0002] Natural plants are increasingly favored by people because of their rich resources, less toxic and side effects, no drug resistance, and no harmful residues. The ingredients contained in natural plants are very complex, which can be divided into active ingredients, ineffective ingredients and toxic ingredients. Active ingredients include terpenoids, glycosides, organic acids and trace elements. There are many extraction methods for effective active ingredients of natural plants, and the traditional extraction methods mainly include decoction, dipping, and reflux extraction. The decoction method is convenient and easy, but there are many impurities in the decoction liquid, which is pro...

Problems solved by technology

[0003] In recent years, many domestic and foreign scholars have continuously explored and optimized the extraction process of plant effective active ingredients, and some new extraction and separation technologies have emerged, such as microwave, ultrasonic, ultrafine pulverization, supercritical, etc. Although these new Technology has made significant progress compared with traditional technology, but the problems of poor water solubility and low utilization of active ingredients have not been fundamentally solved, and some technologies are limited to laboratory research due to special equipment, and cannot be applied to industrial production practice

It can be seen that the imperfection of extraction technology has always been a key issue restricting the further research, development and application of effective plant active ingredients.
