- Abstract
Two new chromone derivatives (1 and 2), together with four known (3–6) ones, were isolated from the stems of a local sun cured tobacco (Fenghuang tobacco, widely cultivated in Shifang prefecture, Sichuan Province). Their structures were elucidated by spectroscopic methods, including extensive 1D and 2D NMR techniques. Compounds 1 and 2 were tested for their anti-tobacco mosaic virus (anti-TMV) activity. The results showed that compounds 1 and 2 exhibited high anti-TMV activities with inhibition rates of 35.8 and 28.6% at the concentration of 20 μM. These rates are close to that of the positive control.
