An older method for terazosin was reworked in order to reduce the analysis time from 90 min (2 × 45 min) to below 5 min. The method in European Pharmacopoeia (Ph.Eur.) investigates the specified impurities separately. The reason of the different met

The original aim of this study was to develop a method for the determination of baicalin from membrane vesicles. The unconventional chromatographic separation (“inverse gradient elution” on a reversed phase column) was due to a lucky chance, whic
