Abstract

Background and objectives: Many members of the Amaryllidaceae are regarded as toxic. The toxic constituents that occur in the whole family are referred to as the Amaryllidaceae alkaloids. The main aim of this study was the identification of alkaloid compounds from Galanthus transcaucasicus Fomin, a medicinal plant from Amaryllidaceae. Methods: Planar and column chromatography techniques were used for isolation of alkaloid components. GC/MS analysis was carried out for the identification of alkaloid compounds. Results: Silica gel column chromatography of the alkaloidal extract of G. transcaucasicus bulbs afforded seven fractions. Preparative thin layer chromatography of these fractions led to the isolation of compounds 1 (nerinine)and 2 (homolycorine). Galantamine was not detected in any of these fractions. Conclusion: Our findings showed that G. transcaucasicus could be a new source of bioactive alkaloids for possible applications in pharmaceutical industries.
