This study was conducted to investigate the antioxidant, antibacterial, anthelmintic, and cytotoxic activities of the crude methanol extract of Bonamia semidigyna (Roxb.) leaves and its derived fractions in different experimental models. Leaves of B. semidigyna were extracted with methanol (MBS) and the resultant successively fractionated into n-hexane (NBS), petroleum ether (PBS), chloroform (CBS), and ethyl acetate (EBS) soluble fractions. Later, the plant extractives were investigated for antioxidant, antibacterial, anthelmintic and cytotoxic properties. Phytochemical study was carried out using standard methods and polyphenols content were determined by spectrophotometric techniques. Antioxidant activity was evaluated by DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity, hydrogen peroxide ( H2O2) scavenging activity, ferric reducing power, and total antioxidant capacity assays. Disc diffusion technique used to evaluate the antibacterial efficacy and anthelmintic activity was determined using aquarium worm (Tubifex tubifex) whereas cytotoxicity was evaluated using brine shrimp lethality bioassay. The phytochemical study revealed the presence of alkaloids, flavonoids, terpenoids, tannins, saponins, phenolic, steroids, sterols, quinones, oxalate, coumarins, and emodins in the plant extractives. In addition, the quantitative phytochemical analysis showed the significant amount of polyphenol contents. In antioxidant assays, the crude methanol extract and EBS fraction exhibited the most potent antioxidant activity among all the extractives. The crude methanol extract and EBS fraction also possessed significant antibacterial and anthelmintic potentials while moderate cytotoxic activities were found for all the plant extractives. The present study confirmed that the crude methanol extract of B. semidigyna and its EBS fraction, possibly due to its high polyphenol contents possess significant antioxidant, antibacterial, and anthelmintic properties.

Achyranthes aspera L. (Prickly Chaff flower) is an imperative Asian herb that has been known for numerous healing powers. The aim of this research is to investigate the pharmacological i.e., antidepressant and anxiolytic properties of the methanol extract of aerial part of A. aspera (MEAA) by in vivo and in silico approaches. Additionally, thrombolytic potential of the crude extract has also been explored. The antidepressant and anxiolytic investigations were performed by force swimming test (FST), tail suspension test (TST), and hole board test (HBT) in mice, whereas clot lysis activity test was conducted using thrombolytic experimental method. Furthermore, in silico studies were appraised with Discovery studio, PyRx, UCSF Chimera whereas, PASS prediction, and ADME/T was implemented using online tools. Treatment with MEAA revealed significant (p < 0.05) reduction of immobility time in FST and TST, increased head dipping and decreased the latency of time in HBT. Besides, MEAA produced significant (p < 0.001) clot lysis activity at a minimum dose. In the computer-aided approach, among all the proteins, the docking score has been revealed ranging from − 2.31 kcal/mol to − 7.4 kcal/mol. Spathulenol, diazepam and hydroquinone showed the best binding affinity and all compounds were found safe in ADME/T study. The outcomes of this research demonstrate that MEAA may provide potential for mitigating depression, anxiety, and coagulation.
