Problems solved by technology

At present, due to the excessive utilization of the wild resources of golden ears, the resources have formed a great threat
The traditional artificial cultivation method has a long cycle, and it takes several months to form a generation of fruiting bodies
The long-term cultivation process results in the instability of fruiting body components, especially those bioactive substances, making extraction of active ingredients from fruiting bodies less commercially viable

Abstract

The invention discloses stereum hirsutum fermentation liquor and sesquiterpene which are produced by fermenting stereum hirsutum liquor, as well as applications thereof, and particularly relates to a production technology process of sesquiterpene cultured and obtained by the stereum hirsutum liquor, and the hypoglycemic efficiency of sesquiterpene. Repeated tests and study show that a culture solution produced by the production technology contains sesquiterpene, a mouse with hyperglycemia takes the culture solution orally, and then blood sugar and fructosamine of the mouse can be reduced remarkably, therefore, the stereum hirsutum culture solution is confirmed to have the application for preparing healthy drinks and medicines capable of reducing the blood sugar. The culture solution is liquor with the color ranging from aurantium to tawny, and the sesquiterpene content in the culture solution is 0.4 mg / mL-4.0 mg / mL. According to the invention, not only is a new way explored for the deep development and utilization of the stereum hirsutum, but also an ideal traditional Chinese medicine is provided for controlling the blood sugar.

Description

technical field [0001] The present invention relates to biological fermentation and the field of medicine, specifically the present invention relates to the method for producing the culture solution of B. pilosa containing sesquiterpene through the cultivation of B. pilosa, and the nutrient solution or sesquite of B. pilosa obtained by the method The crude terpene, and the pharmaceutical composition and / or health product containing the fermentation broth or the crude sesquiterpene have a drug for preventing and / or treating diabetes, especially it has a hypoglycemic effect, so the culture fluid of Stella pilosa Or the crude sesquiterpene can be used to prepare health products and / or medicines for lowering blood sugar, making it an ideal medicine for lowering blood sugar. Background technique [0002] Diabetes is a common and frequently-occurring disease among middle-aged and elderly people. The complications caused by diabetes seriously endanger human life and health. The ex...
