DODONAEA ANGUSTIFOLIA EXTRACTS: A PHYTOCHEMICAL STUDYAbstract
In order to determine whether the leaves, bark, and stem extracts of the Dodonaea angustifolia plant, which is commonly found in Eritrea, contain any potentially bioactive substances like flavonoids, alkaloids, triterpenoids, saponins, tannins, steroids, proteins, and cardiac glycosides, this study was carried out. Samples of plant parts were gathered in the Eritrean regions of Habrengaka and Balwa. The extraction process employed methanol, diethyl ether, and ethanol as solvents. Plant extracts were subjected to preliminary phytochemical examination and Thin Layer Chromatography (TLC). Elution was carried out using the step gradient technique, where the mobile phase consisted of polar and non-polar solvents in various ratios. The leaf, stem, and bark extracts of all three solvents utilized included alkaloids, anthraquinones, glycosides, essential oils, phenolics, saponins, and terpenoids. The ethanolic stem extracts and leaf extracts of all three solvents contained flavonoids, whereas the methanolic and diethyl ether stem extracts as well as the bark extracts of all three solvents did not. All three solvents\' ethanolic leaf and bark extracts included steroids, but only the methanolic leaf and bark extracts contained tannin.
