High-pressure liquid chromatographic assay of quinestrol tablets.
A specific assay for quinestrol was developed using high-pressure liquid chromatography. The estrogen was separated from tablet excipients on a chemically bonded hydrocarbon column utilizing acetonitrile-water as the mobile phase. Linearity studies were carried out using peak height measurements, and the detector response to the concentration of the steroid was confirmed. This procedure was rapid, accurate precise, and specific for the assay of the synthetic estrogen in the presence of formulation excipients and structurally similar estrogens.
