Abstract:
The present invention provides a method for extracting  Tremella  polysaccharides by using buffer solution, which comprises the following steps: leaching  Tremella  powder in a buffer solution with heating to obtain the leachate; subjecting the said leachate to solid-liquid separation and obtaining the liquid component which contains  Tremella  polysaccharides; subjecting the said liquid component to alcohol precipitation, and the precipitate obtained is  Tremella  polysaccharides. According to the method of the invention, various buffer solutions can achieve the extraction rates of  Tremella  polysaccharides up to 33:12%, which is 3 to 4 times of that of the traditional water extraction method, and greatly improve the extraction yields of  Tremella  polysaccharides.

Claim (Index 8):
The method for extracting  Tremella  polysaccharides according to  claim 1 , wherein the time of alcohol-precipitating in step 3) is 8-14 h.
