Green Synthesis of Tecoma stans Flower and Leaf Extracts: Characterization and Anti-Proliferative Activity in Colorectal Cancer Cell Lines

Since times immemorial, many plant species have been utilized to cure severe diseases. A wide range of diversification has been observed in various medicinal plants, which are indeed able to cure several deadly diseases. The presence of secondary metabolites is a high priority for their medicinal characteristics. This study focused on T. stans (Yellow bells), a shrub that grows profoundly in tropical and sub-tropical regions. Although many studies have been done on the medicinal value of this plant, not much has been done on cancer treatment and nanomedicine. Green synthesized silver nanoparticles are an eco-friendly approach to delivering the drug to the target size. Nano appearance is an add-on advantage of these compounds. Hence, it is emerging in medicine. Colorectal cancer is the fourth deadliest one globally. Hence the synthesized silver nanoparticles of T. stans flower and leaf extracts showed cytotoxically and wound healing properties on colorectal cancer cell lines (HCT 116 and SW 480). Synthesis of silver nanoparticles confirmation is done by Ultra Violet Visible spectrophotometry and Particle size analyzer. All the results showcase the beneficial effects of silver nanoparticles synthesized plant extracts and may be used as a novel medicine in the field of chemotherapy.
