The objective of the present study was to evaluate the anxiolytic, antidepressant, and anticonvulsant activity of the methanolic extract of Swertia corymbosa (SCMeOH). After acute toxicity test, oral treatment with SCMeOH at doses of 125, 250, and 500 mg/kg behavioral models of open field, elevated-plus-maze, actophotometer, rotarod, pentylenetetrazole, isoniazid, and maximal electroshock induced seizure models were utilized. In open field test, SCMeOH (125, 250, and 500 mg/kg) (P < 0.01, P < 0.001) increased the number of rearings. However, the number of central motor and ambulation (P < 0.01, P < 0.001) were reduced. Likewise, the number of entries and the time spent in open arm were increased while the number of locomotion was decreased (P < 0.001) in elevated-plus-maze and actophotometer test, respectively. SCMeOH (125–500 mg/kg) protected the mice against the pentylenetetrazole and isoniazid induced convulsions; it causes significant (P < 0.01 and P < 0.001) dose dependent increase in latency of convulsion. Treatment with SCMeOH reduced the duration of the tonic hind limb extension induced by electroshock. Two major compounds such as gentiopicroside and swertianin were analyzed by HPLC system.
Anxiety and Convulsion are the most prominent, crippled and cruel neurological diseases in recent times. There are many indigenous plants have beneficial properties to treat mental disease and psychic complaints. Evaluation of anxiolytic and anticonvulsant activity of leaf and root ethanolic extracts of mirabilis jalapa in rat models were carried out using standardized experimental methods. The dried leaves and root was macerated with ethanol separately and administered the discern dose of 200 mg/k g p.o. and 400mg/kg p.o. from each extract and employed in Elevated Plus Maze test (EPM) and Open field test (OFT) with 2mg/kg i.p of Diazepam as a standard drug to assess the anxiolytic activity. Maximal electroshock induced convulsion (MES) (Phenytoin-20mg/kg i.p as a standard drug) and Pentylenetetrazol (PTZ) induced seizures analyzed where Diazepam (5mg/kg) i.p as a standard drug to assess the anticonvulsant activity. Substantial changes in all tested activities EPM, OFT in anxiety model and MES, PTZ in anticonvulsant model were observed. The results revealed that ethanol leaf extract (400 mg/kg p.o.) was more impetus due to the high amount of flavonoid, phenolic compounds, steroids, terpenoid contents possess tremendous anti-anxiety whereas the ethanol root extract (400 mg/kg p.o.) and ethanol leaf extract (400 mg/kg p.o.) produce significant anticonvulsant potential effect compared to the control and standard drug treatment group. This study suggested that the plant M. jalapa is a much more active compound consistent medicinal plant to derive a potent drug against anxiety and convulsion.
In the present study, the Ficus pumila have taken to analyze the proteins by their preliminary characters from the database and predicted vital role of different sequences. The F. pumila (Creeping fig) is a prostrate/climbing shrub, experiments proved various active phytochemicals and antioxidant, antimicrobial, antimutagenic, analgesic, anti-inflammatory, antiproliferative, hypoglycemic, hypolipidemic, antihyperprolactinemic, anticholinesterase, nephroprotective properties. In addition to all metabolites, it also constitutes specific proteins that were evaluated through insilico homology modeling. Though it is considered as a poisonous weed, the protein present in this plant is evaluated by physicochemical, phylogeny and amino acid proportions by protparam, Swiss model, SOPMA, Clustal omega tools to describe its structural features and to understand molecular function. The computed theoretical isoelectric point (pI) found to be more than 7 indicates basic nature of proteins. The aliphatic index ranges 67-113 indicates thermal stability of proteins. The predicted Grand average hydropathy(GRAVY) shows possibilities of enhanced interaction of these proteins with water by lowest value. Functional analysis of these proteins was performed by SOSUI server which predicted transmembrane helix and solubility. Secondary structure analysis was carried out by SOPMA revealed that Alpha helix and random coil dominated followed by extended strand, and beta turns among secondary structure elements. The modelling of three-dimensional structure of proteins was performed by Swiss model. The model was validated using protein structure checking tool- VADAR. Particularly, NAD(P)H –quinoneoxidoreductase and Glyceraldehyde-3-phosphate dehydrogenase structures were analysed by phylogenetic analysis to trace relationship and reported. The results suggesting its possible role in cellular and metabolic functions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
