Of the crude extracts, 95.1% were active at a concentration of 50 mug/ml. Fifteen (27.8%) extracts showed more than 50% activity at 10 mug/ml and were studied for XOD inhibition. All were active against XOD at 5 0 mug/ml but only 6 (40%) showed up to 60% inhibition. Ethyl acetate extracts from the bark of Weinmannia dichotoma Brongniart & Gris, Weinmannia monticola Daniker and Cunonia linearisepala (Guillaumin) Bernardi and from the roots of Codia incrassata Pampanini, as well as methanol extract from the bark of Pancheria brunhesii Pampanini, exhibited the highest activities (between 70% and 86% XOD inhibition at 50 mug/ml). In view of these preliminary results, New Caledonian Cunoniaceae species appears to be promising material for the isolation of bioactive compounds. specialized PLANTE UTILE ESPECE ENDEMIQUE PROPRIETE PHARMACOLOGIQUE OXYDATION BIODIVERSITE NOUVELLE CALEDONIE 076PLAMED02 40 7 526-533 2002 1388-0209 https://www.documentation.ird.fr/hor/fdi:010078662 10.1076/phbi.40.7.526.14690 1388-0209 [F B010078662] https://www.documentation.ird.fr/hor/fdi:010078662 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers20-08/010078662.pdf IRD - Base Horizon / Pleins textes 2020-08-28 2020-09-17 fdi:010078662 fre
