Abstract
Aim: The present study explored the pharmacological and insilico studies of ethanolic seed extract of Chenopodium quinoa.
Materials and Methods: The screening of in vivo anti- amnesic activity of the ethanolic seed extract of Chenopodium quinoa was carried out using Actophotometer and Rotarod apparatus. The extract exhibited active constituents like myristic acid, palmitic acid, eicosadienoic acid, pentadecanoic acid, tocopherols, stigmasterol, β-sitosterol, quercetin, benzoic acid, kaempferol, arachidonic acid, benzofuran and 2-bromodecanoic acid. In silico approaches like docking studies (Mcule software) and Ramchandran plot (procheck), online softwares were used in the study to establish mechanism of action of active constituents present in the extract.
Results: The extract treated groups at doses (200 mg/kg and 400 mg/kg, bd.wt) showed significant anti-amnesic activity. The basal activity score in actophotometer is as an indicator for impairment of learning and memory. Fall of time by rotarod is used to evaluate learning and memory in rodent models of CNS disorders as in case of amnesia. The results revealed that quercetin, kaempferol, myristic acid, palmitic acid, stigmasterol, lenolenic acid, pentadecanoic acid, tocopherols, arachidonic acid and standard donepezil have got highest glide scores against selected Protein Data Bank (PDB ID): 1EVE, 2FY4, 7CUM and 3EJ8. According to Ramachandran plot a good quality model would be expected to have over 90% in the most favoured region. Proteins like PDB ID: 1EVE, 2FY4, 7CUM and 3EJ8 showed almost 80-90% favoured region which clearly indicates that the selected proteins in the present study are of good quality.
Conclusion: Our research unveiled that ethanolic seed extract of Chenopodium quinoa possessed significant anti- amnesic activity.
