Abstract

The invention discloses a method for continuously obtaining plant secondary metabolites by tissue culture. The method comprises the following steps of: (1) obtaining plant materials in batches; (2) generating and inducing the plant secondary metabolites; and (3) collecting and extracting the plant secondary metabolites. The invention further relates to a reactor device for the culture, wherein the upper part of the device uses a layered culture design of plant tissues and organs, so that cultures can be conveniently collected in a staging manner through the design of a multilayer culture rack; the lower part of the device uses a split type design, so that a liquid storage tank can be conveniently dismounted, and desired products can be obtained by collecting culture liquid; and furthermore, the inhibition on the continuous generation by the concentration of the secondary metabolites can be reduced by replacing the culture liquid, so that the secondary metabolites can be continuously obtained. The method and the device provided by the invention have the advantages of large flux, convenience in operation and low cost.

Description

technical field [0001] The invention belongs to the field of plant biotechnology; in particular, it relates to a method for continuously obtaining active ingredients such as plant secondary metabolites through tissue culture and a device for realizing the method. Background technique [0002] Secondary metabolites are non-essential small-molecule organic compounds produced by secondary metabolism in a class of cell life activities or in the normal operation of plant growth and development, and their production and distribution are usually specific to species, organs, tissues, and growth and development stages . It can be divided into seven categories: phenylpropanoids, quinones, flavonoids, tannins, terpenes, steroids and their glycosides, and alkaloids. Secondary metabolites in medicinal plants are the key components for their medicinal effects. [0003] Plant secondary metabolites are a kind of adaptation of plants to the environment, which is the result of the interacti...
