Abstract:

The paper aims to establish a method for the determination of polysaccharides in Auricularia and compare the polysaccharide content of Auricularia in different varieties and regions. Anthrone-sulfuric acid method was used to determine the content of polysaccharides in Auricularia auricula and Auricularia polytricha from different habitats, and the methodological investigation was conducted. The results showed that: the concentration of dextran had a good linear relationship with its absorbance in the range of 3.27-23.61 μg/mL (R2=0.9993), with an average recovery rate of 101.2% and RSD of 3.5% (n=9). The polysaccharides content of A. auricula from Jiangshan, Benxi and Zhangzhou was 4.1%, 3.0% and 3.5%, respectively; the polysaccharides content of A. polytricha from Jiangshan and Xuzhou was 4.1% and 3.6%, respectively. The method is suitable for the determination of polysaccharides in Auricularia. There was certain difference in the polysaccharides content of A. auricula from different habitats, but not for the A. polytricha. The overall difference in the polysaccharides content between the two varieties was not obvious.
