Abstract

The invention provides a method for extracting phillyrin from forsythia, which relates to a novel method for extracting phillyrin by the steps of soaking with ethyl alcohol solution, adding surfactant and heating by microwaves. The traditional product generally has the defects of low yield rate, poor stability, high production cost and the like. The method comprises the following steps of: crushing forsythia into 16 meshes; adding 58% ethyl alcohol solution for soaking; adding surfactant which accounts for 0.03-0.3% of the weight of the mixture; heating by microwaves, standing and filtering; adding 58% ethyl alcohol solution into residues for soaking; heating by microwaves, standing and filtering; combining filter liquors, evaporating solvent by using a rotary evaporator, adding a small amount of methyl alcohol solution, adding alumina and uniformly stirring, and evaporating. The operations are performed on the basis of official method, the phillyrin is put on a treated neutral alumina column to elute and evaporate, and then the phillyrin powder is prepared. The invention is used for extracting phillyrin.

Description

Technical field:

[0001] The invention belongs to the technical field of traditional Chinese medicine preparations, and in particular relates to a new process for extracting forsythin. Background technique:

[0002] The traditional extraction methods mainly include: water decoction, percolation, water boiling-alcohol precipitation extraction, etc. In the process of traditional Chinese medicine preparation, microwave, as a new energy source, has the characteristics of strong penetration, fast heating and uniform heating. In the present invention, microwaves are used for the extraction of forsythin, the active ingredient of the traditional Chinese medicine Forsythia, compared with the traditional decoction process, the process is more cumbersome, time-consuming, energy-consuming, low in yield, and poor in product stability. Defects such as high production costs. Invention content:

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art...
