These chemical varieties also called chemotypes are endowed with numerous pharmacological properties (antifree radical, antibacterial, antiinflammatory, antiproliferative, hypotensive, antimalarial, antifungal activities, etc.). This plant also contains anti-sickle cell phytomarkers such as ursolic acid (a triterpene acid) and verbascoside (a phenolic compound). <em>L. multiflora </em>reduces oxidative stress by increasing the content of reduced glutathione (essential for the protection of erythrocytes) and nitric oxide (vasodilator effect).</p> <p><strong>Conclusion and perspectives</strong>: The results of this literature review show that in addition to its numerous documented biological properties, <em>L. multiflora </em>also reduces oxidative stress by increasing the content of glutathione and nitric oxide and can thus relieve sickle cell disease. However, the anti-sickle cell activity of this plant species has not yet been scientifically validated although the plant is used in the treatment of anemia in Traditional Medicine. Therefore, it is desirable that a more thorough study be carried out on <em>L. multiflora </em>in order to determine the different chemotypes from the Democratic Republic of Congo (DRC) and then to evaluate the anti-sickling, antihemolytic and anti-radical activities and the effect of these chemotypes on the osmotic fragility of sickle cell erythrocytes.</p> Masengo Ashande Colette Emmanuel Lengbiye Moke Clément Inkoto Liyongo Benjamin Zoawe Gbolo Dorothée Dinangayi Tshilanda Damien Sha-Tshibey Tshibangu Robijaona Rahelivololoniaina Baholy Ilumbe Bayeli Guy Koto-te-Nyiwa Ngbolua Pius T.

Schum (Zingiberaceae): A Mini Review https://journalsarjnp.com/index.php/SARJNP/article/view/30145 <p>According to the World Health Organization (WHO), more than 80% of the population in Africa in general and in the Democratic Republic of the Congo (DRC) in particular, resorts to Traditional Medicine to solve the problem of primary health care. In this study we had reviewed the relevance of <em>A. angustifoolium</em> in phytochemical composition, traditional use and biological activities based on scientific results obtained from Google Scholar, PubMed, Sciencedirect, Web of Science, Scopus and Chemical Abstracts. Moreover, after compiling the research data of several authors, the results show that this plant is of great interest because it has a wide range of biological properties like antioxidant, antiageing, antiparasitic, anti-nociceptive activities. This wide range of biological properties of <em>A. angustifolium</em> would be much attributed to the essential oil compounds such as β-pinene and β-caryophyllene which are the major compounds in this plant. This review will therefore guide future research on the use of <em>A. angustifolium</em> β-caryophyllene rich-extract as anti-inflammatory medicine for the management of Sickle cell anemia<em>.</em></p> Clément L.
