Comparison of Phenol-sulfuric Acid and Anthrone-sulfuric Acid Methods for Determination of Polysaccharide in Rubus crataegiflolius Bunge
摘要
Abstract
Objective] The phenol-sulfuric acid method and anthrone-sulfuric acid method were compared on determination of the polysac-charide content in Rubus crataegiflolius Bunge..[Method] The conversion factor was measured with refined polysaccharide for glucose, and comprehensive evaluation was carried out by linear relationship, precision, reproducibility, stability and recovery rate.[ Result] The results showed that the linear relationship between glucose concentration and absorbance was good in the range of 5-40 μg/mL, and the average recov-ery rate was equal to or higher than 97% with good reproducibility (RSD=1.7%), the content of polysaccharide determined by phenol-sulfu-ric acid method and anthrone-sulfuric acid method were 3.78% and 4.02% .[ Conclusion] Phenol-sulfuric acid and anthrone-sulfuric acid methods are accurate and reliable, and suitable for determination of polysaccharide in R.crataegiflolius.关键词
