Abstract:: ... 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 ...

Abstract:: ... Two new anthraquinones, alataquinones A and B (1 and 2), together with two known anthraquinones (3 and 4), were isolated from the barks 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-tobacco mosaic virus (anti-TMV) activity. The results showed that compounds 1–4 exhibited moderate a ...
