| Abstract: | A stable and simple method to measure the content of momordica charantia L. polysaccharide was established: after the conversion coefficient of polysaccharide to glucose was obtained, the content of polysaccharide was measured by phenol-sulfuric acid method. The method is simple, rapid and accurate and suitable for the quality evaluation of momordica charantia material and products. |
