Activity Evaluation of Polysaccharides from Tremella Aurantialba and Its Application in Cosmetics
The polysaccharides of Tremella aurantialba were extracted and prepared from fresh Tremella aurantialba by water extraction and alcohol precipitation.The structure of Tremella aurantialba polysaccharides was analyzed using infrared spectroscopy,Congo red test and thermogravimetric analysis.The contents of polysaccharides,glyoxalates and reducing sugars of Tremella aurantialba polysaccharides were determined by chemical composition.The in vitro anti-inflammatory and repairing activities of Tremella aurantialba were evaluated by the anti-inflammatory assay of RAW264.7 cells and the in vitro scratch assay of human immortalized keratinocytes(HaCaT)cells.The results show that Tremella aurantialba polysaccharides has good anti-inflammatory and repairing activities.The serum prepared by using it as a raw material is characterized by mildness and non-irritation,and has a good application prospect in cosmetics.
