PT Journal AU Marti, G Eparvier, V Litaudon, M Grellier, P Gueritte, F TI A New Xanthone from the Bark Extract of Rheedia acuminata and Antiplasmodial Activity of Its Major Compounds SO Molecules JI Molecules PY 2010 BP 7106 EP 7114 VL 15 IS 10 DE Rheedia acuminata; Clusiaceae; xanthones; antiplasmodial activity; cytotoxicity AB Bioassay-guided fractionation of the ethyl acetate bark extract of Rheedia acuminata led to the isolation of the new compound 1,5,6-trihydroxy-3-methoxy-7-geranyl-xanthone (1), together with four known compounds 2-5. These compounds were tested in vitro for their antiplasmodial activity on a chloroquine-resistant strain of Plasmodium falciparum (FcB1) and for their cytotoxicity against the human diploid embryonic lung cell line MRC-5.
