    Lens culinaris L., has been widely recognized for its medical applications. LC-ESI-TOF-MS identified 22 secondary metabolites including phenolics, flavonoids, and anthocyanidin glycosides among its total extract (LCTE). The study aimed to apply LCTE as a biogenic material for reducing and capping the silver nanoparticles (LC-AgNPs). The ynthesized LC-AgNPs were characterized using different techniques. The UV absorption was observed at λmax 379 nm. LC-AgNPs were spherical, with 19.22 nm average size. The face cubic centre nature was demonstrated by HR-TEM and XRD. The LC-AgNPs were then evaluated for their anticancer and antimicrobial potentials. LC-AgNPs showed an extremely potent cytotoxic activity against MCF-7, HCT-116 and HepG2 cell lines (IC50= 0.37, 0.35 and 0.1 µg/mL, respectively). LC-AgNPs induced significant apoptotic effects in the three examined cancer cell lines. LC-AgNPs resulted in sequestration of cells in G1 phase of the cell cycle in both MCF-7 and HCT-116 cells, meanwhile it trapped cells at the G2 phase in HepG2 cells. Moreover, the antimicrobial activity of LC-AgNPs was highly confirmed against Klebsiella pneumoniae and Acinetobacter baumannii. Molecular docking study designated Kaempferol-3-O-robinoside-7-O-rhamnoside and Quercetin-3-D-xyloside as the topmost LCTE active constituents that caused inhibition of both Bcl-2 and IspC cancer targets in combination with the produced silver nanoparticles.
