Abstract

The invention discloses an application of a wild chrysanthemum extract in preparation of a drug or a sunscreen product for preventing and treating photoinduced skin injury diseases. The research results show that (1) a wild chrysanthemum flower extract can prevent UV-induced photoaging damage and skin cancer; (2) the wild chrysanthemum flower extract can significantly inhibit UV-induced skin vasodilatation and proliferation; (3) the wild chrysanthemum flower extract can significantly inhibit UV-induced skin blood flow increase; (4) the wild chrysanthemum flower extract can significantly inhibit UV-induced epidermal atypical hyperplasia; (5) the wild chrysanthemum flower extract can inhibit UV-induced skin ROS level rise; and (6) the wild chrysanthemum flower extract can reduce the UV-induced skin inflammation level so as to inhibit the occurrence of skin cancer. The research results show that the wild chrysanthemum flower extract can play an important role in preventing and treating photoinduced skin injury diseases and preparing novel sunscreen products.

Description

technical field [0001] This application relates to the new application of the extract of wild chrysanthemum, especially the application of the extract of wild chrysanthemum in the preparation of medicines or sunscreens for preventing and treating light-induced skin damage diseases. Background technique [0002] Clinical studies have confirmed that ultraviolet (ultraviolet, UV) radiation can cause skin photodamage and even skin cancer. With the prolongation of UV irradiation time, the skin tissue at the irradiation site undergoes a photocarcinogenic evolution process of skin photoaging→solar keratosis→skin cancer. Skin cancers include squamous cell carcinoma, basal cell carcinoma, malignant melanoma, malignant lymphoma, idiopathic hemorrhagic sarcoma, sweat gland carcinoma, dermatofibrosarcoma, angiosarcoma, etc. Clinical treatments for skin cancer include radiotherapy, photodynamic therapy, and surgery. However, few medicines are used for the prevention and treatment of sk...
