N. auteur aut IRD Favela-Torres E. auteur aut IRD text journalArticle eng text/pdf born digital access Ellagic acid (EA) was quantified by reversed-phase high-performance liquid chromatography (RP-HPLC) coupled with photodiode array detection (DAD) in five fine-powdered plants collected from the semiarid region of Mexico. Samples analysed included Jatropha dioica branches (Dragon's blood), Euphorbia antisyphyllitica branches (Candelilla), Turnera diffusa Willd leaves (Damiana), Flourensia cernua leaves (hojasen) and Punica granatum husk (pomegranate) at two maturity stages ("turning" or intermediate and maturated fruit, considered as positive controls). The results demonstrated high EA concentrations in all tested samples which are novel sources of this natural antioxidant. The method developed for the EA analysis is fast and it showed an excellent linearity range, repeatability, intra-and inter-day precision and accuracy with respect to the methods reported for the EA analysis. specialized Ellagic acid Semiarid plants Hplc analysis 076 020 62 4 440-444 2008 0366-6352 https://www.documentation.ird.fr/hor/fdi:010042669 10.2478/s11696-008-0042-y 0366-6352 [F B010042669] https://www.documentation.ird.fr/hor/fdi:010042669 https://www.documentation.ird.fr/intranet/publi/2008/08/010042669.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2008-09-19 2017-08-23 fdi:010042669 fre
