摘要:

The least squares line correlating Id/Is (the ratio between the signal integral values of the drug to the internal reference standard) and concentration was derived and found linear in the range of 10.0–35.0 mg chloramphenicol and 12.0–28.0 mg streptomycin. Each drug was assayed in combination with its degradation product in a ratio of 33 to 300% for the former and 33 to 200% for the latter. Commercial tablets were also assayed for the two components chloramphenicol and streptomycin existing in a ratio 1:1.
