Abstract

Two neolignans 3a-allyl-5-methoxy and dimethoxy-2-(3,4`-methylenedioxy phenyl)-3-methyl-2,3,3a,4,5,6-hexahydro-6-oxobenzofurans and four minor alkaloids (bracteoline, o-methyl bracteoline, a-dehydroreticuline and unknown alkaloid) have been isolated from the wood stem and stem bark of Licaria arminiaca F. Lauraceae. These alkaloids although known were isolated for the first time from the genus Licaria. The structures of three of them were deduced from spectral and chemical evidence.
