Phytochemical screening and evaluation of antioxidant, anti-inflammatory, antimicrobial, and membrane-stabilizing activities of different fractional extracts of Grewia nervosa (Lour.) Panigrahi

Abstract

BackgroundGrewia nervosa (Lour.) Panigrahi, a medicinal herb native to the steep forested region of Bangladesh, is utilized as a treatment for a variety of diseases or conditions, including dysmenorrhea, paratyphoid, bone fractures, jaundice, kidney stones, dyspepsia, heat stroke, cold, fever, diarrhea, hepatitis B, ingestion, and anthelmintic medication. This research aims to investigate the phyto-pharmacological qualities of this herb. MethodsThe herb was extracted using absolute ethanol followed by fractionation with n-hexane and chloroform. Following an initial investigation of phytochemicals, antioxidant, anti-inflammatory, antimicrobial, and membrane stabilization activities were assessed using the DPPH, egg albumin model, disc diffusion method, and erythrocyte hemolysis model, respectively. ResultsA preliminary phytochemical report suggests that G. nervosa contains reducing sugars, gums, amides, alkaloids, glycosides, flavonoids, steroids, tannins, flavonoids, and saponins. In a concentration-dependent approach, its fractional extracts displayed promising antioxidant, anti-inflammatory, antimicrobial, and membrane-stabilizing activity. It was seen that all fractions had a statistically significant capacity to prevent RBCs from hemolyzing, which suggests a potent membrane stabilizing function in-vitro. ConclusionTaken together, G. nervosa possesses important secondary metabolites and exhibits in-vitro antioxidant, anti-inflammatory, antimicrobial, and membrane stabilizing capacities. This endorses the conventional usage of G. nervosa, although additional study is needed on this potentially beneficial plant.
