The umbelliferone/herniarin ratio in herbal preparations of chamomile was determined by high-performance thin-layer chromatographic analysis (HPTLC).

Abstract

The umbelliferone/herniarin ratio in herbal preparations of chamomile was determined by high-performance thin-layer chromatographic analysis (HPTLC). Plant material was extracted in 150 ml of warm H2O for 10 min, then the residual plant material was extracted with 150 ml of MeOH for 1 h. The herbal preparations containing ligulate florets showed higher content of coumarin if compared to other parts of the flower-heads. The ratio umbelliferonel hemiarin was lower than 1:5 in technological preparations.
