Extract the effective components of roselle and evaluate skin care effect
Abstract:This paper discusses extraction method of roselle, ultrasonic-95% ethanol extract and ultrasonic ethyl acetate extract antioxidant activity,and water absorption,water loss of crude extract.crude extract as effective natural moisturizing ingredients is added to skincare emulsion.Through the discussion of configuation craft, product quality inspection and study compatibility in emulsion , the results show that:(1) By UV spectrophotometry test, hydroxyl radical scavenging、DPPH radical scavenging show ultrasonic-95% ethanol extract is stronger antioxidant activity.(2) roselle crude extract by two different solvents both show better results in water absorpotion and water loss test.(3) crude extract is added to skincare emulsion, and by 40°C heat detection , -5°C cold detection ,centrifugation, sample is no statified or separation.It is proved that roselle crude extracet added to emulsion is stable.It also shows roselle has a prospect of application on anti-aging、moisturizing in cosmetics.
