Dicoma tomentosa and Alhagi maurorum are perennial herbaceous plant having multiple medicinal health benefits. The free radicals are generated in the body as metabolic products of several reactions. These free radicals cause multiple harms to the cell, on their cell wall, to the DNA and cause number of diseases. In the present study, the plants were selected and collected from Rajasthan and were shade-dried. The powder was formed of leaves and stem of both the plants. The methanolic extract was prepared for further studies and the enzymatic and non-enzymatic potential of evaluated through their standard protocols. Dicoma tomentosa and Alhagi maurorum both showed strong antioxidant potential. While comparing both the plants with standard, the stem of Dicoma tomentosa was found having comparatively strong antioxidant potential. Keywords: Alhagi maurorum, Dicoma tomentosa, antioxidant potential, in-vitro study, comparative evaluation.

AbstractObjectivesRauvolfia vomitoria is a medicinal plant used traditionally in Africa in the management of several human diseases including psychosis. However, there is inadequate scientific information on the potency of the phenolic constituents of R. vomitoria leaf in the management of neurodegeneration. Therefore, this study characterized the phenolic constituents and investigated the effects of aqueous and methanolic extracts of R. vomitoria leaf on free radicals, Fe2+-induced lipid peroxidation, and critical enzymes linked to neurodegeneration in rat’s brain in vitro.MethodsThe polyphenols were evaluated by characterizing phenolic constituents using high-performance liquid chromatography coupled with diode array detector (HPLC-DAD). The antioxidant properties were assessed through the extracts ability to reduce Fe3+ to Fe2+; inhibit ABTS, DPPH, and OH radicals and Fe2+-induced lipid peroxidation. The effects of the extracts on AChE and MAO were also evaluated.ResultsThe phenolic characterization of R. vomitoria leaf revealed that there were more flavonoids present. Both aqueous and methanolic extracts of R. vomitoria leaf had inhibitory effects with the methanolic extract having higher significant (p≤0.05) free radicals scavenging ability coupled with inhibition of monoamine oxidases. However, there was no significant (p≤0.05) difference obtained in the inhibition of lipid peroxidation and cholinesterases.ConclusionThis study suggests that the rich phenolic constituents of R. vomitoria leaf might contribute to the observed antioxidative and neuroprotective effects. The methanolic extract was more potent than the aqueous extract; therefore, extraction of R. vomitoria leaf with methanol could offer better health-promoting effects in neurodegenerative condition.
