Determination of the polysaccharide in Verdihong paint / 药学实践杂志

ABSTRACT

Objective To establish the determination method of the polysaccharide in Verdihong paint .Methods The anhy-drous dextrose was used as the control , 0.2%anthrone-sulfuric acid as the stain , the content of polysaccharide was determined by ul-traviolet spectrophotometer at the wavelength of 620 nm.Results The polysaccharide curve was linear within a range of 1.9~34.2μg/ml, linear equation was Y=0.033 X-0.006 7 (r=0.999 9), the average recovery was 98.6% with RSD of 1.06%(n=6). Conclusion This method was convenient , stable and coud be used to assay content of the polysaccharide in Verdihong paint .
