An aqueous preparation derived from fenugreek (Trigonella foenum-graecum) was investigated as a plant-based component in the preparation of copper oxide particles. The submitted account describes microwave treatment of a mixture containing fenugreek extract and a copper precursor, followed by drying and powder collection. Structural, spectroscopic and microscopic measurements were used to examine the recovered material. The reported absorption response was concentrated in the ultraviolet region, with a feature near 270–290 nm. Infrared bands suggested the presence of organic surface associated species, while diffraction reflections were assigned to monoclinic CuO (reference pattern JCPDS 48-1548); a Scherrer crystallite dimension of approximately 24 nm was reported. Electron micrographs showed irregular grains assembled into pronounced aggregates. Agar diffusion tests indicated inhibition of Escherichia coli and Staphylococcus sp., although the control identity and dose scheme require clarification. These observations support further investigation of fenugreek-assisted CuO preparation and its preliminary antibacterial response, subject to confirmation of the experimental protocol and reproducibility.
