ABSTRACT
Objective To establish the method for content determination of total flavonoids and polysaccharides in Radix Codonopsis Lanceolatae from Mount Taishan.MethodsThe content of the total flavonoids was determined by UV spectrophotometry and the polysaccharide content was measured with the phenol-sulphuric acid method.ResultsThe optimal detective wavelength was 510nm for the total flavonoids.Satisfactroy linear relationship with the Absorbability was achieved when the mass concentration of rutin was within a range of 8～48?g/ml(r=0.9986).The average recovery rate was 99.31%(RSD=1.82%,n=5).The optimal detective wavelength was 490nm for the polysaccharides.There was good linear relationship between the Absorbability and the content of glucose in a range of 5～50?g/ml(r=0.9964) with an average recovery of 99.12%(RSD=1.49,n=4).ConclusionThis method is sensitive,simple and accurate,and it can be used for the quality control of Radix Codonopsis Lanceolatae from Mount Taishan.
ABSTRACT
OBJECTIVE:To probe into the regular pattern,related factors and prognosis of hemolytic reactions induced by Puerarin injection.METHODS:A total of 44 hemolytic cases induced by Puerarin injection reported in 26 papers of domestic journals published since 1994 were analyzed.RESULTS:Of the 44 cases collected,31 were males and 13 females,with a mean age of(67.5?9.6) years.The hemolytic reactions were induced either by Puerarin injection or Puerarin for injection with a mean dose of(445.2?123.8)mg and a mean concentration of puerarin(in infusion) of(1.55?0.52) mg?mL~(-1).The hemolytic reactions occurred chiefly after administration of puerarin for 7 consecutive days(7.96?3.84 days on average) and appeared as acute hemolytic anemia.The puerarin specific antibody was noted in immunological test.10 patients including 9 males and 1 male died at a mean age of(72.1?5.7) years.CONCLUSION:The occurrence and turnover of Puerarin Injection - induced hemolytic reactions are related to many factors,to which great attention should be paid.
