This research aimed to identify and isolate the chemical constituents of various plant species, including Diospyros buxifolia, D. tomentosa, D. ferra, D. lotus, Balanites aegyptiaca, Rhus parviflora, Polygonum recumbens, and Pyrus pashia. The study involved the extraction and chromatographic separation of compounds from these plants, leading to the identification of various triterpenes, steroids, and other chemical constituents such as friedelin, epi-friedelinol, p-sitosterol, lupeol, betulin, betulinic acid, and maslinic acid, among others. The research concluded with the detailed characterization of these compounds, including their melting points, optical rotations, and spectroscopic data, which contribute to the understanding of the phytochemical profiles of the studied plants and may have implications for their medicinal properties.
