Abstract

Abstract:

wo 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 μg/mL among the tested samples indicated almost the same ABTS cation radical scavenging activity with BHT, a- tocopherol and (+)-catechin at the same concentration. Lupanine and the alkaloidal extract showed almost the same butyrylcholinesterase inhibitory activity with galantamine at 200 μg/mL.
Keywords: Leontice leontopetalum L. subsp. ewersmannii; Berberidaceae; lupanine; anticholinesterase.

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.
