Abstract
In this study, the detailed phytochemical composition of two medicinal plants was investigated and their importance in silver nanoparticles (AgNPs) synthesis was highlighted. Aqueous extracts from the leaves of both plants were used for various analytical techniques, including UV-vis spectroscopy, Gas chromatography-mass spectrometry (GC-MS), Fourier transform infrared spectroscopy (FTIR) and Thin layer chromatography (TLC). Quantification of total phenolics and flavonoids in different fractions of plant extracts revealed significant concentrations. TLC profiling showed a higher abundance of free phenolic and flavonoid compounds compared to bound forms in both plants, suggesting that they contribute significantly to total phenolic and flavonoid content. UV-vis spectra from 200 to 600 nm revealed the presence of aromatic rings and chromophores in leaf extracts. Furthermore, the GC-MS analysis identified several bioactive compounds, some of which were found to be common between these two species. The results demonstrate that various bioactive compounds such as phenols, flavonoids, alkaloids, carotenoids and terpenoids were present in these plant species. These compounds efficiently serve as both reducing and stabilizing agents during phytofabrication of AgNPs, consequently eliminating the need for the use of hazardous chemicals.
