Their structures were elucidated by spectroscopic methods, including extensive 1D and 2D NMR techniques. Compounds <strong>1-5 </strong>were tested for their antitobacco mosaic virus activities. Compounds <strong>1</strong> (20 μM) showed moderate anti tobacco mosaic virus activity with inhibition rates of 18.2 %. Compounds <strong>2-5</strong> showed low anti tobacco mosaic virus activities with inhibitory rates below 10 %.</p>}, number={17}, journal={Asian Journal of Chemistry}, author={Meng, Chun-Yang and Han, Yi and Duan, Yuan-Xing and Chen, Jin-Xiong and Hu, Qiu-Fen and Gao, Xue-Mei}, year={2013}, month={Nov.}, pages={9517–9519} }
