Lycorine and galanthamine have various biological activities. A reliable HPLC method coupled with DAD detection was developed and validated for the determination of galanthamine and lycorine in Galanthus trojanus and G. cilicicus. A simple method for the extraction of the alkaloids in low-mass plant samples was employed utilizing columns pre-packed with diatomaceous earth (Extrelut (R))). This method was applied to the aerial parts and bulbs of G. trojanus and G. cilicicus (Amaryllidaceae) collected during the flowering season. The chromatographic separation was performed using an isocratic system with a mobile phase of trifluoroacetic acid-water-acetonitrile (0.01:92.5:7.5) applied at a flow rate of 1 mL min(-1) and using a diode array detector. Validation procedures showed that the method was specific, accurate and precise. The highest amount of lycorine (0.012 %) was detected in the bulbs of G. trojanus collected from Can (Canakkale), whereas the aerial parts of this species collected from Bayramic (canakkale) was not found to contain this alkaloid. In G. cilicicus samples, lycorine was only determined in the bulbs, giving yields of 0.004 %; galanthamine yields were between 0.015-0.016 %, but none of the G. trojanus samples contained this latter alkaloid.
