Abstract

The invention discloses an application of edible vegetable oil, which is characterized in that it is used to increase the content of Poria cocos triterpenes in the cells of Poria cocos mycelia. The invention adds edible vegetable oil to the culture medium of the fully grown Poria cocos mycelium, which can significantly increase the content of the poria cocos triterpene in the cells of the poria cocos mycelium. The preferred scheme can even increase the content of Poria cocos triterpenes to more than 4 times. Edible vegetable oil is safe to eat, and a small amount can induce the synthesis of triterpenes. The invention uses the edible vegetable oil as the inducer to realize the high-level expression of the triterpene content in the poria cocos.

Description

technical field [0001] The invention belongs to the field of biotechnology, and more specifically relates to the application of edible vegetable oil in increasing the content of Poria cocos triterpenes in the cells of Poria cocos mycelia. Background technique [0002] Poria cocos (Poria cocos (Schw.) Wolf) is a large medicinal fungus belonging to the phylum Fungi, Basidiomycetes, Polyporaceae, Polyporaceae, and Poria cocos (Poria cocos), which has been used in my country for thousands of years. Modern science has confirmed that the chemical components of Poria cocos include polysaccharides, triterpenoids, sterols, alkaloid amino acids, etc., and one of the most important medicinal components is Poria cocos triterpenoids, which have anti-tumor, liver protection, regulating immunity etc. Increasing the content of triterpenoids in Poria cocos plays an important role in the wide application of Poria cocos. [0003] Current studies have shown that methyl jasmonate, acetic acid,...
