Anatomical characteristic and comparison enter the contents total alkaloids of Peganum harmala (Zygophyllaceae) the high plateaus of the area of Djelfa (Algeria)

The purpose of our work is to know the Algerian natural resources in producing plants of alkaloids indolic and improve the production of alkaloids in Algeria considering the interest which these products represent, while being interested in the extracts of a species of the family of Zygophyllaceae: Peganum harmala . The objective of this study is the evaluation of the productive capacity of the total alkaloid for their eventual industrial exploitation. The results show a significant variability of the contents total alkaloids between organs collected at the various periods of the year and according to the environmental factors, in particular the climatic characteristics. The majority of the harvested June organs contain a high content of alkaloids. We have the example of the roots harvested June, contain 3,006% of Alkaloids Totals. While those collected the month of April contain 1,128% AT. The largest content was revealed in the seed collected in June with 4,269% AT. According Hammiche and Merad (1997), the alkaloid content rises sharply in the summer, during the period of fruit ripening, when the harvest of the seed. The anatomical study of Peganum harmala revealed the presences of the spots which we suppose of alkaloids are stored everywhere in the organs, but they are more abundant in the collenchyma stems.
