Two new benzolactones, 5-methyl-6-prenyl-isobenzofuran-1(3H)-one (1), 5-hydroxymethyl-6-prenyl-isobenzofuran-1(3H)-one (2), together with four known phenolic compounds (3-6), were isolated from the leaves of Nicotiana tabacum. Their structures were elucidated by spectroscopic methods, including extensive 1D and 2D NMR techniques. Compounds 1-6 were(More)
Two new 2-arylbenzofurans, 2-(4-methoxyphenyl)-3,5-dimethylbenzofuran-7-ol (1) and 2-(4-methoxyphenyl)-3,5-dimethylbenzofuran-6-ol (2), were isolated from the stems of Nicotiana tabacum. 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-TMV and cytotoxicity(More)
