Preparation method of solid abelmoschus manihot polysaccharide extract and application of solid abelmoschus manihot polysaccharide extract in cosmetics

The invention belongs to the technical field of plant polysaccharide extraction, and particularly relates to a preparation method of abelmoschus manihot polysaccharide and application of the abelmoschus manihot polysaccharide in cosmetics. According to the method, a normal-temperature ultrasonic extraction mode is used for replacing a traditional heating reflux mode to extract the abelmoschus manihot polysaccharide, and meanwhile, a Sevage reagent is used for removing protein, so that polysaccharide hydrolysis caused by high-temperature extraction and change of a chemical structure of an extracted product are avoided, and meanwhile, a traditional ethanol precipitation method is also avoided; the problem that the solubility is reduced due to the fact that the physical and chemical structures of the abelmoschus manihot polysaccharide are changed and the abelmoschus manihot polysaccharide cannot be effectively solvated with water molecules in the alcohol precipitation process is effectively solved. The abelmosch
