Abstract

Two new isoquinoline alkaloids, fistulaquinolines A and B (1 and 2), were isolated from the barks of Cassia fistula. Their structures were determined by means of HR-ESI-MS and extensive 1D and 2D NMR spectroscopic studies. Compounds 1 and 2 were tested for their anti-tobacco mosaic virus (anti-TMV) activity. The results showed that the two compounds showed weak anti-TMV activity with inhibition rates of 18.9 and 22.6%.
