Abstract

Nine new methylated galloylquinic acids were isolated from an aqueous fraction of Copaifera langsdorffii (Fabaceae-Caesalpinioideae) leaf hydroalcoholic extract (3-8, 11, 12, and 14), along with three known methylated galloylquinic acids (1, 2, and 15) and four galloylquinic acids (9, 10, 13, and 16). These compounds were characterized by nuclear magnetic resonance spectroscopy and mass spectrometry. They were further tested in a gastroprotection assay (Ethanol-HCl induced ulcer model in mice), in which all of them significantly reduced the total lesion area, and increased the cure ratio in comparison with pantoprazole. Also, the tested compounds displayed cytotoxicity against gastric adenocarcinoma cells. (C) 2016 Published by Elsevier Ireland Ltd. (AU)
