Phytofabrication of cobalt oxide nanoparticles from Rhamnus virgata leaves extract and investigation of different bioactivities.

The tunable cobalt oxide nanoparticles (CoONPs) are produced due to the phytochemicals present in Rhamnus virgata (RhV) leaf extract which functions as reducing and stabilization agents. The synthesis of CoONPs was confirmed using different analytical techniques: UV-Vis spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), dynamics light scatterings (DLS), Fourier-transform infrared spectroscopy (FTIR), energy dispersive X-ray, and Raman spectroscopy analyses. Furthermore, multiple biological activities were performed.

Biological evaluation of some important medicinal plants from Poonch valley, Azad Kashmir, Pakistan.

Objective: To estimate the phytochemical composition, antioxidant, antifungal, cytotoxic and phytotoxic activities of three important medicinal plants of Poonch valley, Azad Kashmir Pakistan.

Methods: Phytochemicals were investigated for both qualitative (phenols, flavonoids, alkaloids and saponins) and quantitative (total phenolic and flavonoid contents) analysis of plant extracts prepared in ethanol, ethyl acetate and benzene. Moreover, antioxidant potential was investigated by screening botanical extracts against 2, 2-diphenyl-1-picrylhydrazyl scavenging assay, phosphomolybdenum and total reducing power assay.
