Polyphenol investigation of Argania spinosa (Sapotaceae) endemic tree from Morocco

Abstract : The leaves of Argania spinosa from Morocco were investigated for flavonoids and condensed tannins. Four flavonol glycosides were identified by 1H NMR as myricitrin, quercitrin, hyperoside and myricetin 3-O-galactoside. UV spectrophotometric 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 could explain the Argan tree adaptation to aridity.
