NEW XANTHONES FROM COMASTOMA PULMONARIUM AND THEIR ANTI-TOBACCO MOSAIC VIRUS ACTIVITY

Two new xanthones, pulmonarxanthone A (1) and pulmonarxanthone B (2), together with four known ones (3-6), were isolated from the whole plants of Comastoma pulmonarium. The structures of compounds 1-6 was elucidated by spectroscopic methods including extensive 1D- and 2D-NMR techniques. Compounds 1-...

Summary:Two new xanthones, pulmonarxanthone A (1) and pulmonarxanthone B (2), together with four known ones (3-6), were isolated from the whole plants of Comastoma pulmonarium. The structures of compounds 1-6 was elucidated by spectroscopic methods including extensive 1D- and 2D-NMR techniques. Compounds 1-6 were also evaluated for their anti-tobacco mosaic virus (Anti-TMV) activity. The results showed that all the isolated compounds exhibited weak anti-TMV activity with inhibition rates in the range of 14.4-22.3%.
