[Abstract]
Object To develop a method for the determination of polysaccharide in TIANCI CAPSULE, which is a new drug dosage fo rm containing the bouillon of fresh water mussels with immunopotentiating activi ty. Methods Total polysaccharide was determined by phenol-sul furic acid method with glucose as the standard, and spectrophotometer assay abso rbency at 490 nm. Results The linear range of polysaccharide w as 10~80 μg/mL, r=0.999 7. The average recovery rate was 98 .67% (n=5), RSD=2.58%. Through sample assay, the content of p olysaccharide was 267.7~300.6 mg in each TIANCI CAPSULE. Conclusion The method is simple, rapid and reliable, and may be used for the q uality control of this preparation.
