This study deals with the preparation of new metal oxide materials derived from metal precursors using a low-cost sustainable green synthesis approach based on natural plant extracts. The preparation process involved the formation of powders of metal oxides by the precipitation method by adding Beetroot (Beta vulgaris) to Ionic aqueous solutions containing zinc chloride  and manganese chloride. Different weight ratios of mineral precursors have been used to study the effect of chemical composition on the synthetic and functional properties of the resulting materials. After that, the prepared mixtures were subjected to heat treatment inside an electric oven to obtain powders of (ZnO) and manganese oxide (MnO). The final weight composition of the prepared materials was approximately 38% by weight of ZnO and 62% by weight of MnO, depending on the stoichiometric conversion of the initial salts to their corresponding oxides. The compositional, morphological and compositional characteristics of the prepared sample were studied using a number of advanced analysis techniques, including Fourier Transform Infrared Spectroscopy (FT-IR), field emission scanning electron microscopy (FESEM), and energy X-ray scattering spectroscopy (EDS). The FT-IR results confirmed the formation of the characteristic metal-oxygen bonds indicative of the formation of ZnO and MnO, while the FESEM images showed a morphological structure at the nanoscale with a heterogeneous distribution of particles influenced by the mechanism of green synthesis adopted in the preparation. The EDS analysis also confirmed the presence of the basic elements of zinc, manganese and oxygen inside the formed structure with a noticeable absence of impurities
