Evaluation of the effects and side effects of pyrrolizidine alkaloids in medicinal plants

Abstract

Medicinal plants are rich in secondary metabolites, the most important of which are alkaloids. Alkaloids are organic compounds that have diverse structural and physiological activity. Pyrrolizidine alkaloids are non-polar compounds that have side effects and harmful effects especially hepatotoxicity in addition to its medicinal properties. Therefore, due to the presence of these materials in some medicinal plants and the importance of these materials and consumption of plants, and monitoring and more precision in these cases, this study was carried out. In this paper, the information have been collected from electronic library resources and from reputable sites such as Google Scholar and Scopus, PubMed, ISI (Web of Science), and the related keywords, which was the benchmark for the period between 1991 and 2019, and about 90 articles and non-electronic resources for pyrolyzidine alkaloids, Medicinal plants, their effects, and their experiences and experiences were evaluated. Pyrrolizidine alkoxides in some dark Vegetable plants such as Leguminosae, Asteraceae, Orchidoceae, Boraginaceae family have been reported. Consumption of herbal products has been commonplace from centuries ago and is vital importance in various parts of the world, today. Many alkaloids are mutagenic and carcinogenic to humans. PAS-containing plants are present in most parts of the world and cause poisoning and damage to humans, livestock and wildlife.Pyrrolizidine alkaloids, which are found in some plants, can be harmed to body tissues, important properties and medicinal effects, of course, have also been reported, which requires it to be used for studying, knowing and recognizing the structure, organs and plants.
