Abstract:
PURPOSE: A composition containing plant glycoprotein extract is provided to prevent or treat wrinkle and inflammation and to improve moisturizing and skin regeneration. CONSTITUTION: A composition for preventing or treating skin wrinkle contains 0.1-30 weight% of glycoprotein as an active ingredient, isolated from Bergenia cordifolia, Rhodiola rosea, Comarum palustre, Abies Sibirica, Betula pendula Buds, or Inonotus Obliquus. A method for extracting the glycoprotein comprises: a step of chopping the plants and mixing with organic acid solution of pH 2-3 to obtain an aqueous solution; a step of adding protease and treating at 30-50°C for 2-24 hours; a step of filtering glycoprotein solution and raising temperature to 85°C; a step of continuously heating for predetermined time for sterilization; and a step of centrifuging to remove foreign materials and drying.
Abstract:
PURPOSE: A cosmetic composition containing melanin for preventing and relieving skin irritation is provided to regulate the expression of inflammatory cytokine and to prevent and treat skin irritation such as dermatitis, skin dryness, smarting, itching, and burning sensation. CONSTITUTION: A cosmetic composition for preventing and treating skin irritation contains 0.01-10 wt% of melanin as an active ingredient. Melanin is derived from a Mucuna pruriens extract. Melanin suppresses the expression of inflammatory cytokine by all-trans retinoic acid. Melanin is prepared by pretreating the Mucuna pruriens extract at pH 8-10 and oxidizing at 15-35 deg. C. for 3-5 days. The cosmetic composition is manufactured in the form of a lotion, a nutrition cream, a massage cream, an essence, an eye cream, a cleansing foam, a pack, or a body lotion.
