Determination of polysaccharide in Tianxiong injection by colorimetry

OBJECTIVE To establish a method for the determination of polysaccharide in Tianxiong injection. METHODS Polysaccharide in Tianxiong injection was determined by colorimetry. RESULTS The linear range of polysaccharide was 10-50 μg·ml -1 (r=0.9999);The average recovery of this method was 98.7% with RSD of 0.83%(n=6). CONCLUSION The method is simple, accurate , reproducible and suitable for the determination of polysaccharide in Tianxiong injection.
