ABSTRACT


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 m g/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 m g/mL.
