Blumea lacera is an edible plant with imperative medicinal values. However, the anxiolytic and antidepressant roles of B. lacera have not been well‐explained. Therefore, the current study aims to explore the impending bioactive metabolites and roles of B. lacera methanol leaf extract (Me‐BLL) in attenuating anxiety and depression through several experimental and computer‐aided approaches. The chemical characterization of Me‐BLL was performed through standard phytochemical and GC‐MS analyses. To explore the neuropharmacological insights, Swiss albino mice were treated with Me‐BLL at doses of 200–400 mg/kg, p.o. The anxiolytic effects were observed employing elevated plus maze (EPM), light–dark box (LDB), and hole‐board (HBT) tests, while antidepressant effects were evaluated using forced swimming (FST) and tail suspension tests (TST). Diazepam (1 mg/kg, i.p.) and fluoxetine HCl (20 mg/kg, p.o.) were used as the reference standard. The phytochemical analyses revealed several bioactive metabolites, including higher contents of total phenolics and flavonoids. The EPM and LDB tests demonstrated an increased time spent in open arms and light box, and the HBT showed an increased number of head dipping, indicating the anxiolytic effects of Me‐BLL. The TST and FST revealed a decrease in immobility time, meaning the persuasive antidepressant effects. The antioxidative effects of Me‐BLL have also been observed prominently. Correspondingly, the computer‐aided investigation confirmed several bioactive lead molecules. Specifically, thymol and cuminol revealed potential anxiolytic and antioxidant effects, while stigmast‐5‐en‐3.beta.‐ol and gamma‐sitosterol possessed promising antidepressant effects. Taken these results as a base, the plant has imperative potentials in managing anxiety and depression‐like disorders., Chemical analysis revealed wide range of bioactive metabolites including phenolics and flavonoids in Me‐BLL. Me‐BLL produced promising anxiolytic effects in EPM, LDB, and HBT in experimental rodents. Me‐BLL revealed significant reduction of immobility time in FST and TST. Lead molecules like cuminol, thymol, and γ‐sitosterol revealed potentials in computer‐aided model.

In the present study, the aerial parts of Achyranthes ferruginea underwent investigation of their in vitro antioxidant and free radical‐scavenging activities in cell‐free conditions, their phytoconstituents using gas chromatography‐mass spectrometry (GC‐MS), and their cytotoxic activity in HeLa cells. A. ferruginea was extracted with 80% methanol and successively fractionated with solvents to yield petroleum ether (PEF), chloroform (CHF), ethyl acetate (EAF), and aqueous (AQF) fractions. GC‐MS analysis revealed that CHF contained ten phytoconstituents, including different forms of octadecanoic acid methyl esters. The total antioxidant and ferric‐reducing antioxidant capacities of the extracts and the standard catechin (CA) were as follows: CA >CHF >PEF >CME (crude methanolic extract) >EAF >AQF, and CA >CHF >EAF >PEF >AQF >CME, respectively. CHF showed the highest DPPH‐free radical‐scavenging activity, with a median inhibitory concentration of 10.5 ± 0.28 µg/ml, which was slightly higher than that of the standard butylated hydroxytoluene (12.0 ± 0.09 µg/ml). In the hydroxyl radical‐scavenging assay, CHF showed identical scavenging activity (9.25 ± 0.73 µg/ml) when compared to CA (10.50 ± 1.06 µg/ml). Moreover, CHF showed strong cytotoxic activity (19.95 ± 1.18 µg/ml) in HeLa cells, which was alike to that of the standards vincristine sulfate and 5‐fluorouracil (15.84 ± 1.64 µg/ml and 12.59 ± 1.75 µg/ml, respectively). The in silico study revealed that identified compounds were significantly linked to the targets of various cancer cells and oxidative enzymes. However, online prediction by SwissADME, admetSAR, and PASS showed that it has drug‐like, nontoxic, and potential pharmacological actions., In this study, we found that the CHF of A. ferruginea has strong antioxidant and cytotoxic properties in different cell lines. GC‐MS quantitative phytochemical screening revealed that CHF contains 10 compounds which has known cytotoxic activity. Therefore, the obtained biological activity of A. ferruginea supports its use as a traditional medicine against different illnesses, and the plant can be considered a potential candidate for treating cancer.
