A METHOD FOR BOOSTING BIOLOGICAL ACTIVITY IN LITHOSPERMUM ERYTHRORHIZON S. ET Z. EXTRACTS USING IRRADIATION

摘要

A method for boosting biological activity of Lithospermum erythrorhizon S. et Z. extracts by using irradiation is provided to improve antioxidation property of Lithospermum erythrorhizon S. et Z and to hinder the activity of elastase and tyrosinase. In a method for boosting biological activity of Lithospermum erythrorhizon S. et Z. extracts by using irradiation, the Lithospermum erythrorhizon S. et Z. extracts comprises shikonin and its derivatives. The radiation is one selected from the group consisting of gamma-ray, electron beam, UV or X rays. The gamma-ray is radiated from one radioactive isotope selected from the group consisting of cobalt(Co)-60, krypton(Kr)-85, strontium(Sr)-90 and cesium(Cs)-137.
