QUALITATIVE, QUANTITATIVE ESTIMATION, SYNTHESIS AND CHARACTERIZATION OF SILVER NANO PARTICLES EXTRACTED FROM DURANTA ERECTA L. LEAVES

Abstract: People and communities in underdeveloped nations frequently employ plant-based medicines. Many different ailments have been treated with Duranta erecta in Asia and Africa. Due to their distinctive characteristics and numerous uses in a variety of disciplines, silver nanoparticles have attracted a lot of attention. In this study, the estimate, synthesis, and characterization of silver nanoparticles derived from Duranta erecta L. leaves are the primary research objectives. The Folin-Ciocalteu technique was used to assess the total phenolic contents. Using a colorimetric assay with aluminum chloride, the total flavonoid concentration was calculated. Triterpenoids, alkaloids, flavonoids, saponins, glycosides, and tannins were all found in the phytochemical screening results. Characterization of silver nanoparticles were done using scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV and FT-IR. Through the use of UVVisible double beam spectroscopy, the creation of nanoparticles was confirmed through the identification of a distinctive absorption peak in the 200–800 nm region. The outcomes showed a regulated, repeatable synthesis method that produced silver nanoparticles with a high degree of purity and stability. Furthermore, transmission electron microscopy (TEM), scanning electron microscopy (SEM) confirmed the shape, size and morphology analysis. These tests confirmed the accurate preparation of circular SNPs with average size of 200 nm range. Fourier-transform infrared spectroscopy (FT-IR) was done for the functional groups identification. Alcohols, ketinimine, alkanes, alkenes, alkynes, aromatic compounds, silver ions, primary alcohols and carbonyl group in cyclic compound were all found in the sample after FTIR examination. The study's findings confirmed that Duranta erecta contains phytochemicals and bioactive substances that may be beneficial to health as well as his research article can help scholars to know deep about the plant Duranta erecta and its activities.
