Determination of polysaccharide in TIANCI CAPSULE / 中草药

ABSTRACT

Object To develop a method for the determination of polysaccharide in TIANCI CAPSULE, which is a new drug dosage form containing the bouillon of fresh water mussels with immunopotentiating activity Methods Total polysaccharide was determined by phenol sulfuric acid method with glucose as the standard, and spectrophotometer assay absorbency at 490 nm Results The linear range of polysaccharide was 10～80 ?g/mL, r=0 999 7 The average recovery rate was 98 67% (n=5), RSD=2 58% Through sample assay, the content of polysaccharide was 267 7～300 6 mg in each TIANCI CAPSULE Conclusion The method is simple, rapid and reliable, and may be used for the quality control of this preparation
