Xanthones from Hypericum laricifolium Juss., and their antiproliferative activity against HEP3B cells Morales Moisela, M. Brel, O. Bourdy, G. Gonzales de La Cruz , M. Castro Dionicio, I.Y. /Carraz, Maëlle Jullian, V. We describe here the isolation of 6 xanthones and one phenyl-y-pyrone, together with 3-epibetulinic and quercetine from the aerial parts of Hypericum laricifolium Juss. (Hypericaceae), collected in Peru. Isolated compounds have been evaluated against proliferation of human hepatocellular carcinoma Hep3B cells. The most active compound was xanthone 3, with an inhibitory concentration (IC) of 12 µM. 2018 text https://www.documentation.ird.fr/hor/fdi:010093165 fdi:010093165 Morales Moisela M., Brel O., Bourdy G., Gonzales de La Cruz M., Castro Dionicio I.Y., Carraz Maëlle, Jullian V..
