Abstract

The invention provides an active isaria cicadae miquel substance and an application thereof in prevention, delaying or treatment of cataract, and belongs to the technical field of active substances. A preparation method of the active isaria cicadae miquel substance comprises steps as follows: isaria cicadae miquel strains activated in a PDA (potato dextrose agar) slant medium are inoculated into a seed solution medium for culture, and a seed solution is obtained; the seed solution is inoculated into a PDA liquid medium containing traditional Chinese medicine extract and Cajanonic acid A for culture, then mycelia and fermentation liquor are dried and smashed, and a fermented product containing the active substance is obtained; the fermented product is extracted in distilled water, an extracting solution is obtained and concentrated into extractum, the extractum is dried, and the active isaria cicadae miquel substance is obtained. Active ingredients in the active isaria cicadae miquel substance obtained with the preparation method can play the gain role, and the active isaria cicadae miquel substance has a protecting effect, delays the pathological process of posterior capsule opacification, delays development of cataract and is expected to be applied to prevention and treatment of age-related cataract and after cataract.

Description

technical field [0001] The invention belongs to the technical field of active substances, and in particular relates to the active substance of cicadae flower and its application for preventing, delaying or treating cataract. Background technique [0002] Cataract refers to the disorder of lens metabolism due to various reasons such as aging, local nutritional disorders, immune and metabolic abnormalities, trauma, poisoning, radiation, etc., which cause lens protein denaturation and turbidity, and eventually lead to vision loss or even loss of vision, which seriously affects patients. daily life and quality of life. With the aging population in our country, cataract has become one of the most important blinding eye diseases. At present, the most important way to treat cataract is to perform lens replacement, that is, to remove the cloudy lens and implant an artificial lens. Although cataract surgery technology has gradually matured, surgical treatment not only brings huge e...
