| Abstract: | Cholic acid and hyodeoxycholic acid in Calculus Bovis Factitiouswere determined simultaneously using dual wavalength K-ratio spectrophotometryat 240 and 300 nm, without separation of other ingredients. The average recoverywas 99.15 and 100.51%, the coefficient of variation was 1.87 and 1.59%. Themethod was simple, rapid and accurate. |
