- Abstract
Two new compounds (1 and 2), together with three known chromone derivatives (3–5), were isolated from Cassia leschenaultiana. Their structures were elucidated by spectroscopic methods, including extensive 1D and 2D NMR techniques. Compounds 1 and 2 were evaluated for their anti-tobacco mosaic virus (anti-TMV) activity. The results showed that compounds 1 and 2 showed potential anti-TMV activities with inhibition rates of 35.6% and 38.7% at the concentration of 20 μM, respectively. These rates are higher than that of the positive control.
