Description and Uses
This noraporphiae alkaloid has been obtained from Litsea japonica and Neolitsea sericea and swells at 11 5-8°C before melting. It is dextrorotatory with [o:lbl + 102.5° (EtOH) and yields a picrate as yellow needles, m.p. 212°C (dec.) and a picrolonate, m.p. 239°C (dec.). The N-methyl derivative is identical with boldine.
Laurolitsine is an alkaloid extracted from Polyalthia longifolia var. pendula.
