Viviparus contectus로부터 콘드로이친 황산의 분리 및 화장품적 특성

다국어 초록 (Multilingual Abstract)

Chondroitin sulfate, sulfated glycosaminoglycan(GAG), is an important structural component of cartilage and nowdays also used as a skin conditioning agent. It is obtained usually from animal sources, such as cow cartilage. However, there are some problems of acquisition of chondroitin sulfate from animal for its safety from bovine spongiform encephalopathy(BSE) and its efficient isolation method.
In this study, we investigated the nature of chondroitin sulfate isolated from Viviparus contectus and confirmed its skin moisturizing effect. We studied the optimum condition for extracting chondroitin sulfate, cytotoxicity and its activity(cell proliferation , cell migration, collagen synthesis). The optimum extraction condition is under the 121℃ 15lb psi, 2 hours by autoclave and yield is 31.1%. By HPLC-GPC chromatograph, we found that the molecular weight of chodroitin sulfate is 360kDa. chondroitin sulfate showed no cytotoxicity up to 0.1% in human dermal fibroblast and promoted cell proliferation in a dose dependent manner. chondroitin sulfate increased type 1 procollagen synthesis 40% at 1% showing higher activity than L-ascorbic acid.
Furthermore in the clinical test to study skin moisturizing effect by corneometer, chondroitin sulfate statistically increased skin moisturizing effect and moisture capacity of skin to 23.4% compared with sodium hyaluronate.
These results indicate that chodroitin sulfate isolated from viviparus contectus showed no cytotoxicity, can improve collagen synthesis, cell proliferation and skin moisturizing effect. Therefore, we suggest this chondroitin sulfate to be a functional cosmetic material.
