Abstract

The invention relates to a preparation method of Beauveria sp. extract with functiosn of a tyrosinase inhibitor and an antioxidant. The preparation method comprises the following operation steps: 1. selecting and culturing Beauveria sp. Strain; and 2. extracting and refining active components from a fermented product, wherein the refining process comprises primary refining and chromatographic refining. The Beauveria sp. and Beauveria sp. extract provided by the invention have tyrosinase inhibiting and antioxidation active effects, and the refined product has the minimum IC50 (50% inhibiting concentration) of 134.5 mu g/ml to tyrosinase and the minimum IC50 of 87.2 mu g/ml to rat liver cell lipid oxidation; the Beauveria sp. extract can be used as articles for daily use to take into effects of whitening, antioxidation, antiaging, preserving, sterilizing, anti-inflammatory and the like; because the Beauveria sp. extract is produced by microorganism fermentation, the production of the Beauveria sp. extract is not influenced by environment and natural resources, and is easy to industrialize and automatize; the process method has low production cost, simple process, stable process, and high success rate and is easy to adjust and control; and the preparation method is suitable for investment of enterprises in various scales.

Description

technical field [0001] The invention belongs to the technical field of extraction and preparation of biological products, and relates to a preparation method of a Beauveria bassiana extract with functions of tyrosinase inhibitor and antioxidant. Background technique [0002] Beauveria bassiana ( Beauveria sp. ) classification: Hyphospora ( Hyphomycetales ) Beauveria bassiana ( Beauveria Vuillemin) fungi; there are three common types of this genus in my country, such as: Beauveria bassiana ( Beauveria bassiana ), Beauveria bassiana ( Beauveria brongniartii ) and Beauveria bassiana ( Beauveria amorpha ), etc., are important entomopathogenic fungi, and are currently mainly used for biological control of pests. Wherein the silkworm is called Beauveria bassiana after being infected with Beauveria bassiana. The role of white silkworm in traditional Chinese medicine in my country is mainly "expelling wind and relieving spasm, resolving phlegm and resolving stagnation"....
