It seemed important to us to explore the nature of the natural antiparasitic substances in some Asteraceae of traditional Saharan medicine.</p> <p><strong>Methods</strong>: Our work focuses on the bioguided phytochemical study, identification and evaluation of the antiparasitic activity of the extract and pure compound of a medicinal species of the sahara Anvillea radiata (Asteracaea).</p> <p><strong>Results</strong>: The effect of plant extracts on parasites and the study of medicinal plants and endemic Saharan species Anvillea radiata by the use of different techniques of extraction, separation and purification were carried out on the aerial part of these plants tested against Giardia intestinalis. The objective of this study is to demonstrate the antiparasitic power of extracts from medicinal plants from the Bechar region. We estimated the inhibition of the parasites Giardia intestinalis subjected to extracts of medicinal plants. The compound exhibited a high anti-giardia activity, with growth inhibition of 96.24%.</p> <p><strong>Conclusion</strong>: These results suggest that Anvillea radiata has several biological activities and could provide a potential natural source of bioactive compounds and be beneficial to human health.</p> Zahira Roucham Abdelkrim Cheriti ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 2022-11-30 2022-11-30 8 3-4 ID789 ID789 10.15419/br.v8i3-4.789 title description none g
