الملخص

This study concentrated on plant species parasitic plants which affect agricultural and forest economy. They belong to the families: Cuscutaceae (Cuscuta hyalina Roth.), Hydnoraceae (Hydnora johannis Beccari.), Loranthaceae (Plicosepalus acaciae Zucc.), Orobanchaceae (Cistanche deserticola Schenk.), (Orobanche ramosa L.) and Scrophulriaceae (Striga hermonthica Del.). This work aimed at classifying parasitic plants in Sudan, development of taxonomic keys and revision of previous taxonomic classification. The study included chemotaxonomy and the comparison between morphological and chemical characters. To indicate similarities and differences, 10 morphological characters were used inaddition to taxonomical description. Plants components were identified with concentration of amino acids, flavonoids, triterpens and alkaloids, using thin layer chromatography with methanol extract. For functional group infrared equipments were used. In addition the percentage of important mineral salts was found using atomic adsorpation apparatus. Results showed that from morphological characters of parasitic plants they have a total index of similarity of 66% and different of 33% of the characters. The study revealed the presence of amino acids, flavonoids, triterpens in all parasitic plants and absence of alkaloids using different indicators. High similarities were found between parasitic plants in functional groups (66%). For essential minerals for example Mg, K were found in high percent in all plant of different host. Combing all the result parasitic plant is similar in morphology and that was comfirmed by the chemical analysis
