Abstract:
The present invention relates to a composition having anti-oxidant, anti-inflammatory, and skin whitening effects and containing a kudzu aerial part extract as an active ingredient. More specifically, the present invention relates to a composition which can promote anti-oxidant, anti-inflammatory, and skin whitening effects without side effects using natural materials. The composition which can promote an anti-oxidant effect according to the present invention concentration-dependently exhibits an anti-oxidant effect as a result of a DPPH experiment. Moreover, the composition which can promote an anti-inflammatory effect according to the present invention can control the generation of NO and the expression of iNOS and COX-2. In addition, the composition which can promote a skin whitening effect according to the present invention can prevent melanin synthesis in cells, prevent melanin synthesis caused by α-MSH, inhibit melanin accumulation, control the expression of melanin synthesis enzymes and factors related to the synthesis, and improve skin whitening effect even at an in vivo level.
Abstract:
PURPOSE: A composition for prevention and treatment of rheumatoid arthritis and osteoarthritis is provided to suppress pain and inflammation of common symptoms in acute and chronic arthritis, and to improve exercise barrier which is a symptom of the chronic arthritis. CONSTITUTION: A composition for prevention and treatment of rheumatoid arthritis comprises an active ingredient mixed with: 350-450 wt% of Kalopanacis Cortex; 350-450 wt% of Chinese quince; 50-150 wt% of first extract which is extracted from Pulvis Aconiti Tuberis Purificatum; 150-250 wt% of Raphani Semen; and 50-150 wt% of second extract which is extracted from Atractylodis Rhizoma. The extract shows an effect which does not have chytotoxin to synoviocyte and chondrocyte. The extract shows effects of improving exercise barrier, and arthritic and analgesia. The extraction solvent for the first extract is 40-60 wt% of alcohol, and the extraction solvent for the second extract is water. [Reference numerals] (AA) Alleviating pain effect
Abstract:
PURPOSE: A method for producing silk-thread peptide is provided, thereby rapidly and cheaply producing the silk-thread peptide, which has a molecular weight of 500-10000 and 100% solubility at pH 4 to 9, in higher yield. CONSTITUTION: The method for producing silk-thread peptide comprises the steps of: inserting 1 part by weight of silk-thread protein into a solution containing 3 to 7 parts by weight of potassium chloride, 1.5 to 3.5 parts by volume(v/w) of ethanol, and 3 to 7 parts by volume(v/w) of water, and heating the solution at 85 to 95 deg. C for 1 to 3 hours to dissolve the silk-thread protein; dialyzing the silk-thread dissolved solution at 20 to 65 deg. C for 25 to 60 hours to remove salts; and adding 0.1 to 3.0%(w/v) of bromelain into 0.1 to 10.0%(w/v) of the silk-thread protein solution and reacting them at 25 to 30 deg. C for 1 to 5 hours.
