The purpose of this study was to prepare a multi-functional skin care product and apply more plant resources the industry. crude polysaccharides from Bletilla striata, Panax ginseng, Tremella fuciformis were extracted under different conditions based on characteristics plants. formula ratio compound striata essence optimized through an orthogonal experiment. moisturizing, whitening, antioxidant properties evaluated by weighing method, tyrosinase activity test, DPPH free radical scavenging respectively. Finally, improvement degree condition detected using water oil test instrument. results showed that polysaccharide contents 18.00±0.5, 41.70±0.7, 20.25±0.6%, optimal for was: extract 12 mg, ginseng 8 g, sodium hyaluronate 20 ultra-pure 50 mL. moisture retention rate 80.00±3.0%, inhibition 69.04±2.2%, 71.03±2.5%. can increase reduce oil. content pores, stains, wrinkles, roughness, acne pigmentation, has potential become functional, natural safe product.
