The results showed that the ethanolic extract significantly outperformed the aqueous extract in phenolic content (7.16 mg. g\u207b\u00b9 and 4.6 mg. g\u207b\u00b9, respectively) and in flavonoid content (4.60 mg. g\u207b\u00b9 and 3.57 mg. g\u207b\u00b9, respectively). The results also showed that the ability to inhibit the DPPH radical increased significantly with increasing concentration of the prepared extract. The ethanolic extract significantly outperformed the aqueous extract in the percentage of inhibition, reaching 67.54% at a concentration of 0.4 mg. g-1 in the ethanolic extract and 63.6% at a concentration of 0.4 mg. g-1 in the aqueous extract. The IC50 values for each were 0.033 and 0.057 mg. g-1, respectively.<\/span><\/p>\n<p><span style=\"font-family: 'times new roman', times, serif;\"><strong>Keywords:<\/strong> saffron, phenols, stigma, antioxidant.<\/span><\/p>\n<p><strong><span style=\"font-family: 'times new roman', times, serif;\">\u00a0Full paper in Arabic: <a href=\"http:\/\/agri-research-journal.net\/SjarEn\/wp-content\/uploads\/v13n3p36.pdf\">PDF<\/a><\/span><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Lorin ali ahmad1* 1 Tartous Research Center, General Commission for Scientific Agriculture Research (GCSAR), Syria.
