gamma fagarine/dictamnus

OBJECTIVE To study the chemical constituents in bark of Dictamnus dasycarpus. METHODS Isolation and purification were carried out on silica gel column chromatography, prepared thin layer chromatography and sephadex LH - 20, et al. The structures were identified by spectral analysis. RESULTS Twelve

OBJECTIVE To investigate the quinoline alkaloids from the roots of Dictamnus angustifolius G.Don ex Sweet (Rutaceae). METHODS The quinoline alkaloids were isolated by various column chromatographic methods and their structures were elucidated on the basis of spectral analysis. RESULTS A new

Eight furoquinoline alkaloids were purified from two plants belonging to the Rutaceae family. Kokusaginine, skimmianine, evolitrine, and confusameline were purified from Melicope confusa, and haplopine, robustine, dictamine, and gamma-fagarine from Dictamnus albus. In this study, the eight

The methanolic extract of Dictamnus dasycarpus root barks afforded one new glycosidic quinoline alkaloid, 3-[1β-hydroxy-2-(β-D-glucopyranosyloxy)-ethyl)-4-methoxy-2(1H)-quinolinone (1), together with nine known compounds, preskimmianine (2), 8-methoxy-N-methylflindersine (3), dictamine (4),
