Abstract

Partial least-squares calibration was used for the spectrophotometric determination of the active compound and preservative in a syrup also containing several light absorbing excipients. The calibration matrix was constructed from laboratory-made mixtures of the analytes and excipients and was used to quantify three samples from different batches. The most suitable conditions for quantitation were determined and the results obtained are compared with those provided by HPLC. © 1994.
