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.

Abstract

The invention discloses a technology for extracting borreria stricta alkali. The technology includes the steps that borreria stricta is pretreated, mixing and grinding are carried out with the mechanochemical technology, ethanol extraction, active carbon decoloration, petroleum ether extraction, sample resin chromatographic column feeding and eluent drying are carried out in a single-grade continuous adverse-current ultrasonic extractor, and borreria stricta alkali is obtained. Compared with the prior art, the technology has the advantages that extraction of borreria stricta alkali is assisted with the mechanochemical technology, the solubility of borreria stricta alkali in an ethanol solution can be effectively improved in the ultramicro-pulverized powder state, and the separating-out rate of borreria stricta alkali is further increased; in the ethanol extraction process of borreria stricta alkali, under the effect of ultrasonic waves, the permeating, dissolving and dispersing speeds in the borreria stricta alkali extraction process can be increased in cooperation with the continuous adverse-flow extraction technology, extraction time is shortened, the use quantity of solvents can be decreased, and the technology for extracting borreria stricta alkali is high in efficiency and low in consumption.

Description

Technical field [0001] The invention belongs to the technical field of extraction of plant active ingredients, and specifically relates to an extraction process of phytopine. Background technique [0002] Natural plants are increasingly favored by people because of their rich resources, low side effects, no resistance to drugs, and no harmful residues. The ingredients contained in natural plants are very complex, divided into active ingredients, ineffective ingredients and toxic ingredients. Among them, cellulose, chlorophyll, gum and inorganic salts are considered as ineffective ingredients, pigments, alkaloids, flavonoids, coumarins, and water quality. Elements, terpenes, glycosides, organic acids and trace elements are the active ingredients. There are many extraction methods for the effective active ingredients of natural plants. The traditional extraction methods mainly include decoction, dipping, and reflux extraction. The decoction method is convenient and easy, but ther...
