Abstract
The leaves of Argania spinosa from Morocco were investigated for flavonoids and condensed tannins. Four flavonol glycosides were identified by H-1 NMR as myricitrin, quercitrin, hyperoside and myricetin 3-O-galactoside. UV sp ectrophotometric and histochemical methods were carried out to quantify and locate flavonoids and condensed tannins from leaves, stems and thorns of A . spinosa. Both high content and cell localisation of total polyphenols cou ld explain the Argan tree adaptation to aridity.
