Extract the effective ingredients of Safflower and study its skin care efficacy
Abstract:Safflower is the tubular corolla of Carthamus tinctorius L. Compositae safflower, Mainly produced in Henan, Hubei, Sichuan, Yunnan, Zhejiang and other places. Safflower is a traditional medicinal plants. Today, more and more Chinese cosmetics favored by consumers. Extracts from medicinal plants of its active ingredients used in cosmetics, has become a popular new trend in cosmetic industry.In this paper, we extract the active ingredient in saffron by ultrasonic extraction and maceration extraction method and determine the optimum extraction technology. extract solution of Safflower is studied in the effects of scavenging hydroxyl free radical ( •OH- ) in vitro to test its antioxidant effects.Finally,the emulsion with 0.02% of the Safflower extract is prepared.The emulsion has been done sensory test and physicochemical test. The emulsion can be observed to have good stability ,which is placed at 40 ° C, and -5 ° C for 24 h.
Keywords: safflower ingredients; antioxidant; free radicals; ultrasonic extraction; maceration extract
