摘要:

A rapid and accurate PMR procedure is reported for the analysis of noscapine as a drug entity and in tablet dosage form. The method is precise with a standard deviation of ± 1. 44% and 1. 12% in the alkaloid and tablets respectively. The results of synthetic mixtures and tablets are comparable to those obtained by B. P. 1973 and NF. XIII procedures. In addition, the PMR spectrum furnishes a specific means of identification of noscapine.
