Abstract: In this study, three extraction methods were carried out to explore the effects of Pseudostellaria heterophylla crude extracts on antioxidant, whitening and moisturizing. The results indicated that the crude extracts by water revealed highest inhibiting rates than those of ethanol and supercritical fluid extraction in ABTS, DPPH free radicals and reactive oxygen species. According to the analysis of whitening, the crude extract by ethanol and water extraction methods was the best in the inhibiting rate of B16 cell melanin content and tyrosinase activity, respectively. Further, crude polysaccharide from P. heterophylla was performed in hygroscopic rate and moisturizing analysis. The results showed that crude polysaccharide had good moisturizing and moisture absorption efficiency, which was close to hyaluronic acid. In addition, the evaluation of skin water loss also revealed a very significant preventation.
