A reverse-phase microcolumn HPLC method with UV detection (330 nm) was developed for quantitative analysis of flavonoids of Matricaria chamomilla flowers using a ProntoSIL-120-5-C18 AQ column (60 mm × 1 mm × 5 μm), gradient elution system 0.2 M LiClO4/0.006 M HClO4–acetonitrile and cosmosiin as a reference compound. Optimal conditions for the hydrolytic process of flavonoids (KOH concentration 0.25%, extraction time 30 min) and the parameters of flavonoids extraction (particle size 0.25 mm, extraction temperature 60°C, a single extraction step lasting 30 min at a ratio 1: 100) were selected. Validation analysis showed that the proposed method is characterized by satisfactory metrological parameters. The limit of detection (LOD) and limit of quantification (LOQ) of cosmosiin were 84 and 255 ng/mL, respectively. The accuracy for cosmosiin content levels 80–120% was less than 101.93–103.00%. The method was used for the analysis of introduced and commercial samples of M. chamomilla flowers.
