The goal of the current task is to synthesize AgNPs through a facile, low-cost, environmentally friendly route. In this method, we use the aqueous leaf extract of Scoparia dulcis Linn, found in the Western Ghats region, because the use of an aqueous medium is critical for reducing time and minimizing the possibility of side effects. The synthesized Ag nanoparticles were evaluated using UV-Visible, FTIR technique, scanning electron microscopy (SEM) with EADX, transmission electron microscopy (TEM), X-ray powder diffraction (XRD). Results confirmed that UV-visible spectroscopic analysis showed the absorbance peak at 460 nm, which implies the formation of silver nanoparticles. The FTIR spectrum aimed to such that biomolecules involved in wrapping and binding AgNPs synthesized by the plant extract. SEM and TEM are used to visualize the size and shape of nanoparticles. The XRD analysis revealed spherical structures with an average grain size of 21nm and a diameter range of 2 to 20nm. The EDAX study also exhibits the presence of 86.34 % Silver and 13.6 % Oxygen. Alzheimer's disease symptoms were controlled with a drug known as an acetylcholinesterase inhibitor. The in vitro acetylcholinesterase inhibitory activity of the AgNPs from Scoparia dulcis plant extract was evaluated using an Ellman's test with an IC50 value of 149µg/ml. The generated nanoparticles significantly inhibit AChE. The SD-AgNPs were examined for antioxidant activity via the DPPH and ABTS assays having IC50 values of 73.29µg/ml and 55.29µg/ml, respectively","PeriodicalId":21063,"journal":{"name":"Rasayan Journal of Chemistry","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69410564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is due to the different physicochemical properties of flavonoids. Furthermore, the function of these flavonoid compounds can be maximized from the initial process of separating them from the plant of origin known as extraction. This study compared the effectiveness and efficiency of using microwave extraction and maceration of Gedi leaves (Abelmoschus manihot L.). Then, the extract was encapsulated to protect the unstable flavonoids. There were two methods to encapsulate the extract in this study. They were the coprecipitation and kneading methods. The result shows that microwave extraction assisted has higher product in less solvent and was time-consuming. The coprecipitation also shows better performance in encapsulating the extract. The calculation of the efficiency of encapsulation was done for 3 different volumes of both methods. The addition of 1 mL extract by coprecipitation showed approximately 92.12%. It was also supported by the data of FTIR and UV VIS.","PeriodicalId":21063,"journal":{"name":"Rasayan Journal of Chemistry","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69411219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Worldwide modern drugs used in healthcare are derived from plants. Several Rhizomes and tubers are important for people due to their edible as well as medicinal properties. The Rhizome and tuberous plants namely Solanum aculeastrum dunal, Elephantorrhiza elephentina, Cadaba aphylla (Thunb), and Adenia glauca which are indigenous plants of Botswana have been so far employed in the treatment of cutaneous, subcutaneous parasitic infection, wounds, dermatological diseases, gastrointestinal system disorders, sexual dysfunction, and sexually transmitted infections. This study was conducted to identify the phytoconstituents by subjecting them to Ultrasound-Assisted Extraction (UAE) with distilled water, methanol, ethanol, chloroform, and hexane, each extract of which was further applied to the phytochemical screening through qualitative and quantitative tests. The extracting yields of Solanum aculeastrum dunal with different solvents gave the values of 13.0% (hexane), 13.0% (chloroform), 66.6% (ethanol), 66.6% (methanol) and 46.6% (aqueous), Elephantorrhiza elephentina 13.0% (hexane), 20.0% (chloroform), 66.6% (ethanol), 80.0% (methanol) and 86.0% (aqueous), Cadaba aphylla 60% (ethanol), 66.6% (methanol) and 53.3% (aqueous), Adenia glauca 40% (ethanol), 40.0% (methanol) and 46.6% (aqueous). Standards were used to determine the total content of alkaloid, flavonoid, phenol, saponin, and tannin (Atropine, Quercetin, Gallic acid, Tannic acid, and Quillaja). The regression coefficient (R2 ) was calculated and for Alkaloids, it is 0.9925, flavonoid (0.9953), phenol (0.9978), tannin (0.9955), and saponin (0.9912) respectively.
