Problems solved by technology

At present, crude torreya resources are scarce, and the tree species grows slowly, and the output of crude torreya alkaloids is low, which is difficult to meet people's living needs. At the same time, it also causes the price of crude torreya alkaloids to be expensive. Therefore, how to increase the output of crude torreya alkaloids become one of the important issues of people

preparation example Construction

[0012] A method for preparing a Torreya alkaloid product. The roots, stems, and leaves of perennial Torreya are selected as explants, cut into strips, sterilized, put into a culture medium to grow symbiotic bacteria, and then obtained from The strains that can metabolize crude torreya alkaloids are isolated from the symbiotic bacteria of torreya torreya, cultivated and fermented, and the fermentation liquid is concentrated and then precipitated to obtain the product. After the activation of the species, put them into an environment with a temperature of 26°C and cultivate them for 48 hours, then inoculate the strains on a petri dish with PDA medium for cultivation, and insert the second batch after 1-2 days after the first batch of strains produce metabolic organisms Crude Torreya symbiotic bacteria, to promote the growth of the second batch of bacterial classification, the second batch of inoculated bacterial classification grows and inoculates in the shake flask that fermenta...

Embodiment 1

[0018] A kind of preparation method of crude torreya alkaloid product, comprises the following steps:

[0019] Step 1. Selection and processing of explants

[0020] Choose the root, stem and leaf of perennial thick torreya as explant, clean the explant with running water, then cut the root into 5-6cm long pieces, remove the old bark and branches and leaves on the stem, and set aside;

[0021] Step 2, sterilization of explants

[0022] Put the treated explants into the ultra-clean workbench, first sterilize them with alcohol with a volume concentration of 75% for 5 minutes, then sterilize them with mercuric chloride with a mass concentration of 0.1% for 12 minutes, wash them with sterile water for 4 times, and put The processed explants were put into sterile water and set aside;

[0023] Step 3, purification and isolation of crude Torreya strain

[0024] Put the sterilized explants into the culture bottles containing the PDA medium respectively, place the culture bottles wit...

Abstract

The invention belongs to the field of plant endophyte separation and microbial fermentation engineering, and in particular relates to a method for preparing a crude torreya alkaloid product. By selecting the roots, stems, and leaves of perennial Torreya as explants, cutting them into strips, sterilizing them, and putting them into the culture medium to cultivate them to grow the symbiotic bacteria of Torreya, and then isolate the metabolizable Torreya symbiotic bacteria from the symbiotic bacteria. Torreya alkaloid strains are cultivated and fermented, and the product is obtained by concentrating the fermented liquid and separating out. In the present invention, in the preparation process of the fermentation liquid, the second batch of strains is inserted after the strains produce metabolic organisms, and the metabolites produced by the previous batch of strains are used to provide nutrients for the second batch of strains, which greatly promotes the production of the second batch of strains. The growth of the bacteria species improves its biological activity, thereby producing a large amount of fermentation liquid and improving the output of crude torreya alkaloids.

Description

technical field [0001] The invention belongs to the field of plant endophyte separation and microbial fermentation engineering, and in particular relates to a method for preparing a crude torreya alkaloid product. Background technique [0002] Torreya is a unique plant in my country, which has high nutritional value and economic value. Torreya alkaloid is one of the important active ingredients of Torreya, which has anti-cancer effects and is often used in medicine. At present, crude torreya resources are scarce, and the tree species grows slowly, and the output of crude torreya alkaloids is low, which is difficult to meet people's living needs. At the same time, it also causes the price of crude torreya alkaloids to be expensive. Therefore, how to increase the output of crude torreya alkaloids become one of the most important issues for people. Contents of the invention [0003] The purpose of the present invention is to provide a method for preparing a crude torreya alk...
