Abstract:

Flowering tops of melilot (Melilotus officinalis (L.) Pallas) were studied, in order to obtain a selective extract, enriched in coumarins.
Macroscopic exam, microscopic exam and a chemical exam (qualitative and quantitative) were performed for this vegetal raw material.
The following anatomic characteristics were identified: fibres with thick walls and surrounded by a sheath containing prism crystals of calcium oxalate; covering trichomes with warty cuticle; glandular trichomes with a short stalk and an ovoid heat; pollen grains with smooth exine and 1- 2 germinal pores.
The raw material contains: flavones (0.180- 0.185 g%, expressed as rutin), polyphenolcarboxilic acids (0.956- 1.066 g%, expressed as caffeic acid), coumarines, triterpenic saponins, tannins, sterols, carotenoids, polysaccharides (mucilages).
Also an enriched coumarine extract was analysed in comparison with the raw material..
