Flax also known as common flax or linseed, is a flowering plant, Linum usitatissimum, in the family Linaceae. The current study used haloperidol-induced catalepsy and reserpine antagonism to investigate in vivo anti- Parkinson's activity and in silico approaches like docking studies (schrodinger software), Ramchandran plot (procheck), ADME and biological activity score using (molinspiration) online software. The n-hexane extract of Linum usitatissinum (HELU) (flax seeds) exhibited various phytochemical constituents like carbohydrates, lignans, alkaloids, phenolic compounds, flavonoids, fatty acids, coumarin derivatives and sterols. Pharmacological tests were studied at 200 mg/kg bd.wt and 400 mg/kg bd.wt, using in vivo behavioural effects like muscular rigidity, tremors, akinesia, grip strength, and locomotory activity. The experiment was designed by giving haloperidol to induce catalepsy and Reserpne to induce Parkinson’s disease-like symptoms. The increased cataleptic scores were significantly decreased by HELU (200 and 400 mg/kg bd.wt., p.o.) in reserpine antagonism model. Docking studies for natural chemicals against PDB ID: 4I6B, 7JOZ, 4XUD, 4OYX were conducted to better understand the ligand-binding affinity of the extract's active ingredients. The results revealed that D-xylose, D-arabinose, L-rhamnose, L-fucose, hesperidin, herbacetin, β-carboline, isoquinoline, ferulic acid, eicosapentanoic acid, docosahexaenoic acid, beta sitosterol, niacin, aesculetin and standard drug levodopa, carbidopa had shown highest glide scores with all the selected proteins which indicate a stronger receptor-ligand binding affinity. Our findings revealed that Linum usitatissimum n-hexane extract has strong anti Parkinson's action.

Aim: To evaluate anti-hyperlipidemic activity of the whole plant of Gossypium herbaceum extract in Wistar Albino Rats. Methods: The whole plant of Gossypium herbaceum were collected and extracted with methanol by soxhlation. It was tested in Triton and Propylthiouracil (PTU) induced hyperlipidemic rat models and antioxidant hydrogen peroxide radical scavenging assay. Results: Basic phytochemical tests resulted in the presence of flavonoids, terpenoids, steroids, phytosterols, carbohydrates, alkaloids, tannins and phenolic compounds. In rat models of hyperlipidemia induced by Triton and Propylthiouracil (PTU), the anti-hyperlipidemic effect of a methanolic extract of the whole plant of Gossypium herbaceum was studied. MEGH (200 and 400 mg/kg, p.o.) treatment greatly decreased the enhanced serum lipids, restored the decreased HDL compared to disease group. Histopathological examinations showed recovery of the damaged liver cells in Propylthiouracil treated group. The extract's capacity to scavenge free radicals caused by hydrogen peroxide was also measured. Ascorbic acid served as the reference. The result demonstrates that the Gossypium herbaceum whole plant's methanolic extract has substantial antioxidant and antihyperlipidemic properties. Docking simulation was done to PDB protein of Lecithin cholesterol acyltransferase, HMG-CoA reductase inhibitor and Antoxidant and viewed in discover studio followed by Ramachandran plot. Conclusion: Methanolic extract of Gossypium herbaceum can be used for management of hyperlipidemia and possess antioxidant activities.

In animal models for screening for anticonvulsant activity, it has been scientifically established that medicinal herbs used in traditional medicine for the treatment of epilepsy possess promising anticonvulsant properties and can be a source of newer anticonvulsants. This study's objective was to evaluate the ethanolic root extract of Clitoria ternatea Linn for its preliminary phytochemical components, anticonvulsant, and anxiolytic effects. Anticonvulsant activity was evaluated against Maximum electroshock (MES) induced convulsion and pentylenetetrazole (PTZ)-induced convulsion model in rats. Using phenytoin (25 mg/kg) as a standard drug, the efficacy of the extract at oral dose levels of 200 and 400 mg/kg were evaluated in an experimental rat model. The marble bury test was used to assess the mice for anxiolytic activity, and lorazepam served as the standard drug at a dose of 0.05 mg/kg. Phytochemical screening revealed that C. ternatea extract contain carbohydrates, flavonoids, alkaloids, proteins, triterpenoids, phenols and steroids. The ethanolic extract significantly decreased the duration of tonic flexion and tonic extension in MES induced model (p<0.05). The ethanolic extract significantly increased the latency of convulsion and decreased the duration of convulsion in PTZ induced model (p<0.05). The ethanolic root extract were found to be significantly decrease the number of marbles buried in the treated groups as compared to control group, indicating anxiolytic activity. According to specific investigations, terpenes and steroids exhibited anticonvulsant effects in some experimental seizure models, including MES and PTZ. Alkaloids and triterpenes, which are phytoconstituents in ethanolic extract of Clitoria ternatea (EECT), might be the basis of its anxiolytic actions. Based on the findings of the study, Clitoria ternatea's ethanolic root extract has anticonvulsant and anxiolytic effects on animals.

The swimming endurance test, anoxic tolerance test, and basal activity by actophotometer were used to assess the antistress activity of a seven-day therapy (200 and 400 mg/kg, p.o.) of the ethanolic extract of Coriandrum sativum (EECS) aerial parts. A method for measuring the in vitro antioxidant activity of hydroxyl radicals was used. In all of the examined models, Coriandrum sativum at both doses demonstrated antistress effects. In the anoxic tolerance test, swimming endurance test, and duration of stay on the rotarod, the EECS treated rats demonstrated enhanced swimming time, duration, and anoxic tolerance time, respectively. The C. sativum's potential to scavenge free radicals, which enhanced the cognitive effect, was utilized to determine the in vitro antioxidant activity. The results demonstrated clearly that the extract's in vivo adaptogenic performance and cognitive improvement were caused by its in vitro antioxidant activity. The EECS treated animals showed increase locomotor scores in basal activity by Actophotometer. The plant secondary metabolites flavonoids, glycosides, triterpenoids, and phenolic components may be accountable for the animals' improved swimming endurance, stress tolerance, and overall performance. This study gave evidence that the ethanolic extract of Coriandrum sativum has antioxidant, anti-stress, and nootropic activity, and that utilizing them by humans as nutraceuticals is beneficial and scientific. By stress reduction in animals, the antioxidant effect provides the pharmacological basis for supporting a healthy memory.

New drug delivery technologies are transforming drug discovery and development, as well as establishing research and development-focused pharmaceutical firms that are accelerating global progress. The bioactive rutin molecule is used in a wide range of food and medicinal goods. Its limited bioavailability and poor water solubility are major issues. Rutin is a polyphenolic natural compound with antibacterial, anticancer, antioxidant, chemopreventive, and anti-inflammatory activities. However, no research has been published to yet to improve its bioavailability and efficacy. As a result, an attempt was made in this study to load rutin into a nanoparticlulate system in order to improve its bioavailability and efficacy. Six formulations (F1-F6) of nanoparticles were prepared by solvent evaporation technique and were evaluated for particle size and shape using Zeta Sizer, Scanning Electron Microscopy (SEM) and Fourier Transform Infra-Red (FT-IR) Spectroscopy. The optimized formulation was further subjected to in vitro evaluation. Practical percent yield, drug entrapment efficiency and In vitro drug release were evaluated. Out of various formulations F1 have shown best results in particle size 80.71 (1-100 nm), particle shape (spherical nanoparticles with a smoothed surface), average size distribution (105.0), zeta potential (-20.6) percentage yield (70.83), drug entrapment efficiency (83.6%) and drug loading (95%). Pure rutin showed incomplete dissolution of 47.69% in 330 min while Rutin loaded nanoparticles gave 94.75% release in 330 min. It is obvious from the foregoing that rutin chitosan nanoparticles were used as a novel drug delivery technology to improve therapeutic efficacy and sustained release features while overcoming issues such as poor solubility and limited bioavailability.
