Two new prenylated compounds, the benzoquinone atrovirinone (1) and the dep
sidone atrovirisidone (2), were isolated from the roots of Garcinia atrovir
idis. Their structures were determined on the basis of the analysis of spec
troscopic data. While compound 2 showed some cytotoxicity against HeLa cell
s, both compounds 1 and 2 were only mildly inhibitory toward Bacillus cereu
s and Staphylococcus aureus.
