dc.description.abstract The castor plant can vary greatly in its growth habit and appearance. The variability has been increased by breeders who have selected a range of cultivars for leaf and flower colors, and for oil production. This work aimed to study the phytochemical characteristics of Ricinus communis L. leaves and stems, through the detection of the polar and apolar content percentages, the presence of the main phytochemicals and the active ingredients via the TLC technique. Stems and leaves of castor plant were collected from the main campus, University of Gezira. The collected parts were cleaned, dried at room temperature under shade away from the direct sunlight. The dried parts were crushed to fine size particles and were then used for the extraction, thin layer chromatography test (TLC) and phytochemical screening in the Laboratory of Food Analysis, Faculty of Engineering and Technology, University of Gezira. The results of this study revealed that, the polar and apolar contents in the leaves were more than in the stems. According to the used materials, R. communis leaves contain more phytochemical classes than the stems. saponins, flavonoids and steroids were detected in the leaves, while, flavonoids and steroids were only detected in stems, whereas, tannins, alkaloids and glycosides were not detected in any tested part. And according to the used materials, R. communis leaves contains more phytochemical active ingredients than the stems which contain fewer number of active ingredients (specially, when methanolic extract was used). The study recommends using the materials and the methods that leads to harvest and detect more classes of phytochemicals. Similar phytochemical screening should be run for all the Sudanese aromatic and medicinal plants in order to establish local database. Also further studies using HPLC technique should be run to identify the obtained active ingredients and further antimicrobial activity tests using different parts (especially seeds and flowers) of this plant should be run. en_US
