| Abstract: | Two new xanthones (1–2), together with four known ones (3–6), were isolated from whole herb of Swertia elata. Their structures were elucidated by spectroscopic methods including extensive 1D- and 2D-NMR techniques. Their anti-tobacco mosaic virus (anti-TMV) activity test revealed that 1–6 showed weak anti-TMV activities with inhibition rate in the range of 15.2–28.8% at the concentration of 20 μM. |
