Abstract

The invention belongs to the technical field of medicines, and particularly relates to high-purity compactin and a process for producing the same on a large scale. Seed media for implementing the process for producing the high-purity compactin on the large scale mainly comprise white granulated sugar, glycerin, KN2PO4, MgSO4.7H2O, vitamin solution and water, and fermentation media mainly comprise white granulated sugar, glycerin, soybean meal, KH2PO4, MgSO4.7H2O, plant extract liquid and water. The high-purity compactin and the process for producing the high-purity compactin on the large scale have the advantages that the fermentative capacity of penicillium citrinum can be effectively enhanced by the aid of the media, and accordingly the compactin yield can be increased; impurities generated by the penicillium citrinum in fermentation procedures can be reduced, and accordingly the purity of the high-purity compactin can be improved; the process for producing the high-purity compactin is low in production cost, high in yield and purity and suitable for producing the high-purity compactin on the large scale.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a process for large-scale production of compatin and the obtained high-purity compatin. Background technique [0002] Combastatin, also known as mevastatin, is a secondary metabolite of fungi and belongs to the HMG-COA reductase inhibitor. Its function is to competitively inhibit HMG-CoA reductase, which is the rate-limiting enzyme of cholesterol biosynthesis. Conbatin was discovered by Akira Endo from the fungus Penicillium Citrinum in 1976, and was isolated from Penicillium brvicompactum by A.G. Brown in 1976. Its molecular formula is C 23 h 24 o 5 , the molecular weight is 390.52. [0003] Compactin can effectively lower cholesterol in the body, and its derivative, pravastatin, has stronger medicinal properties in lowering cholesterol. Compatin can be converted into pravastatin through the hydroxylation of a specific carbon in its structure, that is, Compatin ...
