Abstract:
Objective To study the benzylphenethylamine alkaloids from the bulbs and flowers of Lycoris radiata.Methods Alkaloids were isolated by various column chromatographic methods and their structures were identified by spectral data.Results Fifteen known benzylphenethylamine alkaloids were isolated and identified as lycoramine(1),O-demethyllycoramine(2),N-demethyllycoramine(3),galanthamine(4),lycorine(5),caranine(6),ungminorine(7),narciclasine(8),5-hydroxy-10-O-demethyl-homolycorine(9),hippeastrine(10),ungerine(11),hippeastrine N-oxide(12),O-demethylhaemanthamine(13),haemanthidine(14),and 8-demethoxybostasine(15).Conclusion Compound 15 is first isolated from the plants in Amaryllidaceae,compounds 3,6,9,and 11 are first reported from the plants in Lycoris Herb.,and compounds 2,7,and 14 are isolated from L.radiata for the fast time.The 13C-NMR data of compouds 3,7,and 12 are first reported in the present study.Furthermore,the galasine-type alkaloid is isolated from the plants of Lycoris Herb.for the first time.
