Two new coumarins, 7-(4-hydroxyphenyl)-6H-[1, 3]dioxolo[4,5-g]chromen-6-one (1) and 7-(2-hydroxy-3,4-dimethoxyphenyl)-6H-[1,3]dioxolo[4,5-g]chromen-6-one (2), together with five known coumarins (3–7), were isolated from the roots and stems of flue-cured tobacco (a variety of Nicotiana tabacum L.). 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, and they show potential anti-TMV activity with inhibition rates of 14.5 and 31.2%, respectively.
