Abstract

Recently, there is a growing interest about unsaturated lecithin having excellent characteristics of skin affinity and absorbency. Accordingly, this study intended to develop a natural sulfuration material in order to enhance the stability of oxidation of unsaturated lecithin and substitute existing sulfuration materials which indicate variability and toxicity. As sulfuration components, plenol acid family, 3,5-dihydroxybenzoic acid, and flavanone were analyzed. Total polyphenol content was higher in the root extracts (133.85 mg/g) than in the fruit extracts (53.5 mg/g). Above 100 ppm polyphenol content, the free radical removal efficiency and lipid oxidation prevention of the root extracts were 20.1 and 19.2% superior compared with BHT respectively. Also, the extracts indicated high survival rate of more than 95% below 1250 ppm, showing the stability. For the stability of liposome made from an unsaturated lecithin, the root extracts were superior to the fruit extracts. Especially, 15.1 and 13.9% of sulfuration effect and zeta potential were improved with 9.3% reduced particle size compared with BHT as the control group, respectively.
