摘要：

Isoniazid (INH) anti-tuberculosis drug was determined spectrophotometrically after derivatizing with 2-hydroxy-1,4-naphthoquinone (HNQ) at pH 3 in aqueous-methanolic solution. The reaction conditions were optimized and the derivative absorbed maximally at 365 nm. The Beer's law was obeyed in the range 5-25 mu g/ml. With coefficient of determination 0.9991. The method was applied for the determination of INH in pharmaceutical preparations with coefficient of variation 0.86-0.98.
