Résumé : Tannins were extracted by acetone/water 60:40 from skin and flesh of four cashew apple genotypes from Brazil and Bénin (West Africa), and separated from monomeric phenols. Tannins were submitted to acidcatalysed degradation in the presence of phloroglucinol and the products were analysed by HPLC-DAD/ ESI-MS. Both skin and flesh tannins contained high percentages of (-)-epigallocatechin and (-)-epigallocatechin- O-gallate, followed by minor quantities of (-)-epicatechin and (-)-epicatechin-3-O-gallate; 100% of the compounds were the 2,3-cis configuration. Skin tannins were half as galloylated (_20%) than flesh tannins (_40%). Their weight-average molecular weight (Mw) was high.
