Abstract
- The root and leaf extracts of Launaea cornutahave been locally used in traditional medicine for decades to manage inflammatory conditions and other oxidative-stress-related syndromes; however, their pharmacologic efficacy has not been scientifically investigated and validated. Accordingly, we investigated the in vitroantioxidant activity, anti-inflammatory (in vitro, ex vivo,and in vivo) efficacy, acute oral toxicity, and qualitative phytochemical composition of the aqueous root extract of L. cornuta. The ferric-reducing antioxidant power (FRAP) and the 2,2-diphenyl-2-pycrylhydrazyl (DPPH) radical scavenging test methods were used to determine the studied plant extract’s antioxidant activity. Besides, the anti-inflammatory efficacy of the studied plant extract was investigated using in vitro(anti-proteinase and protein denaturation), ex vivo(membrane stabilization), and in vivo(carrageenan-induced paw oedema in Swiss albino mice) methods. The studied plant extract demonstrated significant in vitroantioxidant effects, which were evidenced by higher DPPH radical scavenging and FRAP activities, in a concentration-dependent manner (p< 0.05). Generally, the studied plant extract exhibited significant in vitro, ex vivo,and in vivoanti-inflammatory efficacy, respectively, and in a concentration/dose-dependent manner compared with respective controls (p< 0.05). Moreover, the studied plant extract did not cause any observable signs of acute oral toxicity, even at the cut-off dose of 2000 mg/Kg BW (LD50> 2000 mg/Kg BW), and was thus considered safe. Additionally, qualitative phytochemistry revealed the presence of various antioxidant- and anti-inflammatory-associated phytochemicals, which were deemed responsible for the reported pharmacologic efficacy. Further studies to characterise bioactive molecules and their mode(s) of pharmacologic efficacy are encouraged.
