Inhibition of Acetylcholinesterase (AChE) is still considered as the main therapeutic strategy against Alzheimer's disease (AD). Many plant derived phytochemicals have shown AChE inhibitory activity in addition to the currently approved drugs for AD. In the present study, methanolic extracts of 20 plants used in Indian Ayurvedic system of medicine for improving cognitive function were screened for acetylcholinesterase inhibitory activity by Ellman's microplate colorimetric method. Out of 20 extracts, Emblica officinalis, Nardostachys jatamansi, Nelumbo nucifera, Punica granatum and Raulfia Serpentina showed IC50 values <100 µg/ml for acetylcholinesterase inhibitory activity. Antioxidant activities of these plants were assessed by DPPH scavenging assay. Among the extracts used, antioxidant activity was highest for Terminalia chebula and Emblica officinalis with IC50 values <10 µg/ml. Considering the complex multifactorial etiology of AD, these plant extracts will be safer and better candidates for the future disease modifying therapies against this devastating disease.

There is no consensus in the literature regarding the ideal protocol for obtaining and preparing cell samples for untargeted metabolomics. Nevertheless, the procedures must be carefully evaluated for proper and reliable results for each organism under study. This work proposes a novel protocol for determining intracellular metabolites in Leishmania promastigotes and is fully optimized for application in conjunction with gas chromatography-mass spectrometry platforms.

The phytochemical profile of various plant species reveals that some compounds possess notable antioxidant and antimicrobial properties. In this study we investigated for the first time, the antioxidant activity (FRAP, DPPH and TAC), total phenolic contents and total flavonoid contents of Delile ex Godr flowers extracts (-hexane, ethyl acetate and methanol) as well as their antimicrobial activity. The results obtained showed that the methanol extract contained the highest content of total phenolics (346.

This study explores the development of electrospun nanofibers incorporating bioactive compounds from (Ashwagandha) root extract, focusing on optimizing extraction conditions and nanofiber composition to maximize biological activity and application potential. Using the Design of Experiment (DoE) approach, optimal extraction parameters were identified as 80% methanol, 70 °C, and 60 min, yielding high levels of phenolic compounds and antioxidant activity. Methanol concentration emerged as the critical factor influencing phytochemical properties.
