Two new alkaloids, 3-(hydroxymethyl)-6,9-dimethyl-7H-benzo[de]quinolin-7-one (1) and 3-(hydroxymethyl)-8-methoxy-6,9-dimethyl-7H-benzo[de]quinolin-7-one (2), together with two known alkaloids (3 and 4) were isolated from the seeds of Cassia alata. Their structures were determined by means of HR-ESI-MS and extensive 1D and 2D NMR spectroscopic studies. Compounds 1–4 were tested for their anti-tobac ...
