Abstract:
Bioassay-guided fractionation of a CHCl(3) extract from the leaves of Ardisia teysmanniana Scheff. (Myrsinaceae) has led to the isolation of three new alkyldibenzoquinone derivatives that showed inhibitory activity in an in vitro assay for UDP-MurNac synthesis. The structures of ardisiaquinone G, H and I were established using MS and NMR spectroscopic methods.
