Abstract: Antifungal activity was determined by the tube dilution method on different extracts of Symphytum sylvaticum Boiss. subsp. sepulcrale (Boiss. & Bal.) Greuter & Burdet var. sepulcrale. The antifungal activity of the isolated compound from the root alkaloid fraction (Echimidine-N-Oxide) was also tested against ten fungal cultures. The activity was found to be mainly due to Echimidine-N-Oxide (ENO). The quantitative determination of ENO was also carried out with capillary gas chromatography in the roots and the aerial parts of the plant.
