The present invention relates to the technical field of preparation of food and cosmetic raw materials. Disclosed are an antioxidant repair Ganoderma lucidum extract and a preparation method therefor. The preparation method comprises: mixing crushed fruit body of Ganoderma lucidum with pure water, and heating and dynamically extracting to obtain a crude extract; standing the obtained crude extract, naturally settling, filtering a supernatant by using a screen mesh, and collecting a crude filtrate; using a disc stack centrifuge to perform secondary impurity removal on the obtained crude filtrate so as to obtain a filtrate; performing fine filtration by using a ceramic membrane having a pore diameter of 400-1200 nm, and collecting a permeate; and finally, concentrating and drying to obtain an antioxidant repair Ganoderma lucidum extract. The preparation method of the present invention is simple to operate and low in cost, and has the advantage of large scale. The finished product is high in controllability and stability, and the Ganoderma lucidum extract which is wide in application and good in effect can be provided for the industries of food, health food, and cosmetics.

The present invention relates to the technical field of preparation of food and cosmetic raw materials. Disclosed are an anti-oxidant repair Ganoderma lucidum extract and a preparation method therefor. The preparation method comprises: mixing crushed Ganoderma lucidum sporocarp with pure water, and heating and dynamically extracting to obtain a crude extract; standing the obtained crude extract, naturally settling, filtering a supernatant by using a screen mesh, and collecting a crude filtrate; using a butterfly centrifuge to perform secondary impurity removal on the obtained crude filtrate so as to obtain a filtrate; performing fine filtration by using a micro-filtration membrane having a pore diameter of 400-1200 nm, and collecting a permeate; and finally, concentrating and drying to obtain an anti-oxidant repair Ganoderma lucidum extract. The preparation method of the present invention is simple to operate and low in cost, and has the advantage of large scale. The finished product is high in controllability and stability, and the Ganoderma lucidum extract which is wide in application and good in effect can be provided for the industries of food, health-care food, and cosmetics.
An Agrocybe cylindracea extract, and a preparation method therefor and pharmaceutical use thereof. The preparation method for an Agrocybe cylindracea extract comprises the following steps: (1) first extracting Agrocybe cylindracea with ethanol to obtain filtrates, concentrating and freeze-drying the filtrates to obtain an ethanol extract; and then extracting, with water, Agrocybe cylindracea residues after extraction with ethanol to obtain filtrates, concentrating and freeze-drying the filtrates to obtain a water extract. The Agrocybe cylindracea extract has the effects of lowering uric acid, alleviating hyperuricemia and gout disease, and treating gouty arthritis and uric acid nephrolithiasis.
