    (Acg Publications, 2011) Kolak, Ufuk; Hacibekiroglu, Isil; Boga, Mehmet; Ozgokce, Fevzi; Unal, Murat; Choudhary, M. Iqbal; Ulubelen, Ayhan
    Two known quinolizidine alkaloids, lupanine and leontiformidine, were isolated from the tubers of L. leontopetalum subsp. ewersmannii. Lupanine having the highest inhibition of lipid peroxidation at 100 mu g/mL among the tested samples indicated almost the same ABTS cation radical scavenging activity with BHT, alpha-tocopherol and (+)-catechin at the same concentration. Lupanine and the alkaloidal extract showed almost the same butyrylcholinesterase inhibitory activity with galantamine at 200 mu g/mL.
