Abstract

The invention relates to an application and a preparation method of a Beauveria sp extract having tyrosinase inhibition activity, specifically to an application of the Beauveria sp extract in preparation of pigmentation and melanoma prevention and treatment tyrosinase inhibitors. According to the present invention, the main effective component in the Beauveria sp extract is 6'-methyl-2',4'-dihydroxyphenyl-4-O-methyl-beta-D-glucopyranoside, and the content is 5-99%; the activity is characterized in that the half-inhibition concentration (IC50) on the tyrosinase is 37.6-638.5 mug/mL; and the Beauveria sp extract having the tyrosinase inhibitor has wide uses, can be adopted as the daily chemical additive, and provides effects of whitening, anti-blackening, anti-aging, pigmentation and melanoma prevention and treatment, and the like.

Description

technical field [0001] The invention belongs to the technical field of extraction, preparation and application of biological products, and relates to the application and preparation method of a Beauveria bassiana extract with activity of inhibiting tyrosinase. Background technique [0002] Classification of Beauveria sp.: fungi of the genus Beauveria Vuillemin in the family Hyphomycetales; there are three common types of this genus in my country, such as: Beauveria bassiana ), Beauveria brongniartii and Beauveria amorpha are important entomopathogenic fungi, 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". The main active ingredient of Beauveria bassiana is considered to be ammonium oxalate, but there is no medic...
