Xanthones from the herb of Swertia elata and their anti-TMV activity [PDF]

Natural Product Research, 2015
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 ...
