| Abstract: | The color condition for detecting polysaccharides in Ganoderma lucidum by phenol-sulferic acid method was optimized.The optimum extracting condition was obtained through single effect factor and orthogonal experiments.The condition of phenol-sulferic acid method was 490 nm maximum absorption wavelength,20 min reaction time and 100 ℃ reaction temperature.The optimum extracting condition was 50 minutes,60 ℃ and 50 ml/g liquid-material ratio.Extraction ratio of polysaccharides under the above condition was 2.58 %. |
