| Abstract: | Objective To establish a method for determination of polysaccharide content in the alcoholic drink of SanqiGouqi. Methods The phenol-sulfuric acid colorimetry method was performed at wavelength of 490 nm with phenol-sulfuric acid as a color reagent. Results The phenol-sulfuric acid colorimetry method had stability and high precision for determination of polysaccharide in the alcoholic drink of SanqiGouqi. The good positive linear relationship was shown in the range of 0.02~0.1 mg/mL, the correlation coefficient (r2) was 0.9998, and the average recovery rate of added samples was 99.89%. Conclusion The established method is suitable for determination of polysaccharide in the alcoholic drink of SanqiGouqi. |
