    Datura stramonium is one of the most intriguing, in part because of its well-known therapeutic and psychoactive properties in the treatment of many diseases. Datura species have been found to exhibit a variety of biological activity. Insecticide, fungicide, antioxidant, antibacterial, hypoglycemic, and immune response boosting properties have been linked to the genus’ species. These effects are linked to the existence of secondary metabolites such as terpenoids, flavonoids, with anolides, tannins, phenolic compounds, and tropane alkaloids, which are the most prevalent atropine and scopolamine in the genus Datura. Ingestion of Jimson weed produces the toxidrome of anticholinergic intoxication. Understanding and recognizing the classic signs and symptoms of anticholinergic intoxication can help clinicians evaluate persons presenting with Jimson weed poisoning. Moreover, this review is to identify the most important phytochemical substances extracted from the Jimsonweed and to characterize their biological activity for health effect and biopesticide application. Biopesticides are less harmful than chemical pesticides because they do not leave harmful residues, generally target one specific pest or a small number of related pests rather than broad spectrum chemical pesticides that affect other beneficial insects, birds, mammals, or non-target species, are effective in smaller quantities, decompose quickly and do not cause environmental problems, and are often cheaper. In conclusion, Datura stramonium, beside its medicinal value, can applicable for biopesticide application and for postharvest loss control of insects such as weevil

    Progress of Food Production and food processing biotechnology in Africa: A Systematic Review

    The increase in human population worldwide has become a major threat to food security and nutrition. Food production and processing sector particularly the agriculture and food processing is asked to satisfy two apparently contradictory needs; to become more productive and at the same time more sustainable. Biotechnology is one of the sectors with significant contribution in modernizing agriculture, food security and nutrition. Africa including Ethiopia has started research in agricultural-food processing biotechnology a few decades ago. However, research and public awareness on biotechnology is inadequate. This review appraises the agriculture/ food production and food processing biotechnology progress in developing societies particularly in Africa so as to understand the roles which agricultural and food processing biotechnology could play therein. The paper concludes with the recommendation that individual countries need to identify their specific national priorities and preferences in food production, and harness the growing body of science and innovations in genetic engineering and food processing to address specific issues. &nbsp; &nbsp
