Abstract

Abstract: Drypetes euryodes (Hiern) Hutch., Drypetes gossweileri S. Moore, Drypetes laciniata Hutch. (Putranjivaceae), Rinorea subintegrifolia O. Ktze, and Rinorea woermanniana (Büttner) Engl. (Violaceae) from Gabon were probed for the presence of glucosinolates (GLs). When present, the GLs were identified and quantified by HPLC analysis. 2-Hydroxy-2-methyl GL (1 ) was the major GL in the cork of D. euryodes . Moreover, 4-hydroxybenzyl GL (2 ) was the major GL in the seed of D. gossweileri whereas the bark contained2 as the minor GL and benzyl GL (3 ) was the major one. In addition, 4-methoxybenzyl GL (4 ), 3-methoxybenzyl GL (5 ), and3 were found in the root of R. subintegrifolia . However, no GL was detected in D. laciniata (leaf and stem), D. euryodes (leaf and stem), and R. woermanniana (leaf and stem-branch). Our results support the hypothesis of the existence of GLs in plants of the Putranjivaceae and Violaceae families (order Malpighiales) . Abstract :
