Unraveling the Phytochemical Profile Variability and Antioxidant Activities of Different Parts of Ammi visnaga (L) Collected from Taounate Region

Abstract

Ammi visnaga is a very popular medicinal plant well known for its biological properties afforded by its dense chemical composition highly dependent on environmental factors. The present study was designed to examine the antioxidant potencies using four complementary assays (Total phenolic content (TPC), total antioxidant capacity (TAC), dihydroxycinnamic acid derivative content (HCA), and cupric ion reducing antioxidant capacity (CUPRAC)) as well as the phenolic profile of different parts of Moroccan Ammi visnaga. The obtained results showed that the flower extract registered the highest amount of TPC (49,71 ± 0,12 mg GAE/g) and antioxidant activity TAC (62.07 ± 2.98 mg AAE/g). Concerning the phenolic profile, the most abundant individual phenolic compounds found in high amounts are chlorogenic acid (56.03%, 11.23% and 32.29 for stem, leaves and flowers, respectively), isorhamnetin_3-O-rutinoside (17.86%, 12.16% and 19.01% for stem, leaves and flowers, respectively), isorhamnetin_3-O-glucoside (15.96%, 10.69%, 10.37% for stem, leaves and flowers, respectively), quercetin_3-O-glucoside (1.61%, 21.11% and 2.85% for stem, leaves and flowers, respectively), kaempferol_3-O-glucoside (1.04%, 3.17% and 7.40% for stem, leaves and flowers, respectively) and isorhamnetin (0.57% 7.59% and 2.77% for stem, leaves and flowers, respectively). The outcomes of this study showed that different parts of A. visnaga contain several bioactive compounds with unique biological properties, so the data required further validation using experimental models.
