Abstract
This study aimed to evaluate the antioxidant, antiarthritic, and anti-inflammatory properties of extracts from the leaves of twelve different medicinal plants in Nepal. We then evaluated the total phenolic, flavonoid, and tannin contents of the extract using in-vitro assays and characterized it using GC-MS analysis. Results revealed that most of the leaf extracts contained phenolic compounds, flavonoids, tannins, alkaloids, and saponins. Few plants also showed the presence of glycosides, phytate, and vitamin C. Among the studied plants, Neolamarckia cadamba exhibited the highest total phenolic and tannin contents, as 241.53 ± 0.20 µg of gallic acid equivalent/mg and 74.48 ± 1.081 µg of tannic acid equivalent/mg, respectively. Ipomoea batatas exhibited the highest total flavonoid content, as 53.051 ± 1.11 µg of quercetin equivalent/mg. Moreover, Raphanus sativus demonstrated significant ferrous ion chelating, 2,2-diphenyl-1-picrylhydrazyl, hydrogen peroxide scavenging, and total antioxidant activities with IC50 value of 4.76 ± 0.68 µg/mL, 5.84 ± 0.14 µg/mL, 6.89 ± 0.16 µg/mL, and 8.99 ± 0.20 µg/mL, respectively. Similarly, Colocasia esculenta and Cicer arietinum exhibited the highest hydroxyl radical and nitric oxide scavenging activities, measuring IC50 value of 7.22 ± 0.56 µg/mL and 9.06 ± 0.10 µg/mL, respectively. Among all the extracts, Amorphophallus paeoniifolius displayed significant human red blood cell (HRBC) membrane stabilization activity (IC50 = 6.22 ± 0.78 µg/mL). Furthermore, Raphanus sativus, Chenopodium album, Cicer arietinum, and Murraya koenigii exhibited the highest inhibitory activities against protein denaturation with bovine serum albumin, antiarthritic, lipoxygenase inhibitory, and proteinase inhibitory, measuring IC50 of 7.48 ± 0.48 µg/mL, 9.44 ± 1.62 µg/mL, 14.67 ± 1.94 µg/mL, and 28.57 ± 2.39 µg/mL, respectively. In conclusion, this study demonstrated the twelve leaf extracts' significant antioxidant, antiarthritic, and anti-inflammatory activities.
期刊介绍:
Journal of Tropical Medicine is a peer-reviewed, Open Access journal that publishes original research articles, review articles, and clinical studies on all aspects of tropical diseases. Articles on the pathology, diagnosis, and treatment of tropical diseases, parasites and their hosts, epidemiology, and public health issues will be considered. Journal of Tropical Medicine aims to facilitate the communication of advances addressing global health and mortality relating to tropical diseases.
