Abstract

The invention relates to the field of plant cell culture and provides a method for acquiring secondary metabolites including panax japonicus saponins and the like with large-scale culture and a bioconversion technology for panax japonicus cells. The method comprises steps as follows: (1), auxins, cytokinins and a coagulator are added to an RW culture medium; (2), explant surface of panax japonicas is sterilized and callus is formed through induction; (3), the callus of the panax japonicas is subjected to subculture, and loose cell clusters are obtained; (4), a culture solution is prepared; (5), the loose cell clusters are transferred into the culture solution for culturing; (6), high-yield cell strains are cultured and screened; (7), the high-yield cell strains are subjected to multiplication culture; (8), a synthetic medium is prepared; (9), cells are continuously cultured in the synthetic medium, and bioconversion is completed; (10), purification is performed after extraction with a solvent. With the adoption of the method, the secondary metabolites of the panax japonicas can be produced, the production cost is low, the culture period is short, the method is not limited by natural environment, and annual production can be realized.

Description

technical field [0001] The invention relates to a method for obtaining secondary metabolites of Panax ginseng, in particular to a method for obtaining compounds such as Panax ginseng saponins by using large-scale cultivation and biotransformation technology of Panax ginseng cells. Background technique [0002] Bamboo ginseng (Panax japonicus C.A. Mey), also known as bamboo ginseng or white notoginseng, is a plant of the genus Panax ginseng in the family Araliaceae. Commonly known as "herb king". Mainly distributed in my country's Jiangxi, Hubei, Guangxi, Sichuan, Guizhou, Yunnan, Tibet and other provinces and regions under alpine bushes, wetlands or beside rocky ditches. It has many different names. The "Dictionary of Chinese Medicine" says: Different books have different titles, such as: soil ginseng, soil essence, blood ginseng ("Hua Jing"), sweet seven, bamboo knot seven ("Herbs") "Convenience Recipe"), Bamboo Ginseng ("Scientific Folk Herbs"), Bamboo Whip Sanqi, Arhat ...
