Because of their widespread availability, low cost, low risk, and lack of side effects, medicinal herbs play a crucial role in traditional medicine all throughout the world. For medicinal purposes, Peristrophe bicalyculata (R.) is being used today. Nees as a nerve system tonic. Plant roots have antibacterial, anti-inflammatory, immunostimulating, and aphrodisiac properties. This plant root may provide health advantages, making it suitable for nutraceutical and functional food compositions. This research examined P. bicalyculata (R.) neuropharmacological effects on memory enhancement to treat cognition-related illnesses and learning and memory disorders. In phytochemical investigation, P. bicalyculata (R.) Nees ethanolic extract has higher phytoconstituents. Spectrophotometric and thin layer chromatography (TLC) plate bioassay detection showed that P. bicalyculata (R.) Nees ethanolic extract inhibits acetylcholinesterase activity. TLC and high-performance thin layer chromatography (HPTLC) were performed on P. bicalyculata (R.) Nees ethanolic extract. TLC and HPTLC spots are well resolved, indicating active ingredients in the extract. Total phenolic, flavonoid, and ascorbic content of P. bicalyculata (R.) Nees ethanolic extract was measured. Ex-vivo tests like lipid peroxidation testing reveal the extract is antioxidant. In conclusion, the ethanolic extract of P. bicalyculata (R.) Nees has memory-enhancing, antidepressant, and neuroprotective properties due to its anticholinesterase potential, effect on neurotransmitters like dopamine and serotonin, and antioxidant profile. More research is needed on its safety, effectiveness, and mechanism of action for therapeutic use.
