In order to discover new natural products against HAT, thirty-seven Vietnamese essential oils (EOs) were screened for their activity in vitro on Trypanosoma brucei brucei (Tbb) and cytotoxicity on mammalian cells (WI38, J774). Based on the selectivity indices (SIs), the more active and selective EOs were analyzed by gas chromatography. The anti-trypanosomal activity and cytotoxicity of some major compounds (isolated or commercial) were also determined. Our results showed for the first time the selective anti-trypanosomal effect of four EOs, extracted from three Zingiberaceae species (Curcuma longa, Curcuma zedoaria, and Zingiber officinale) and one Lauraceae species (Litsea cubeba) with IC50 values of 3.17 \u00b1 0.72, 2.51 \u00b1 1.08, 3.10 \u00b1 0.08, and 2.67 \u00b1 1.12 nL\/mL respectively and SI &gt; 10. Identified compounds accounted for more than 85% for each of them. Among the five major components of Curcuma longa EO, curlone is the most promising anti-trypanosomal candidate with an IC50 of 1.38 \u00b1 0.45 \u00b5g\/mL and SIs of 31.7 and 18.2 compared to WI38 and J774 respectively.<\/jats:p>","DOI":"10.3390\/molecules24061158","type":"journal-article","created":{"date-parts":[[2019,3,25]],"date-time":"2019-03-25T06:56:52Z","timestamp":1553497012000},"page":"1158","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["Evaluation of the Anti-Trypanosomal Activity of Vietnamese Essential Oils, with Emphasis on Curcuma longa L. and Its Components"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2895-1508","authenticated-orcid":false,"given":"Thanh Binh","family":"Le","sequence":"first","affiliation":[{"name":"GNOS Research Group, Louvain Drug Research Institute, Universit\u00e9 catholique de Louvain, UCLouvain, 1200 Bruxelles, Belgium"},{"name":"Department of Pharmacognosy, Hanoi University of Pharmacy, 13-15 Le Thanh Tong, Hoan Kiem, Hanoi 100000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0942-4649","authenticated-orcid":false,"given":"Claire","family":"Beaufay","sequence":"additional","affiliation":[{"name":"GNOS Research Group, Louvain Drug Research Institute, Universit\u00e9 catholique de Louvain, UCLouvain, 1200 Bruxelles, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2381-6144","authenticated-orcid":false,"given":"Duc Trong","family":"Nghiem","sequence":"additional","affiliation":[{"name":"Department of Botany, Hanoi University of Pharmacy, 13-15 Le Thanh Tong, Hoan Kiem, Hanoi 100000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tuan Anh","family":"Pham","sequence":"additional","affiliation":[{"name":"Department of Pharmacognosy, Hanoi University of Pharmacy, 13-15 Le Thanh Tong, Hoan Kiem, Hanoi 100000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marie-Paule","family":"Mingeot-Leclercq","sequence":"additional","affiliation":[{"name":"TFAR Research Group, Louvain Drug Research Institute, Universit\u00e9 catholique de Louvain, UCLouvain, 1200 Bruxelles, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2278-6206","authenticated-orcid":false,"given":"Jo\u00eblle","family":"Quetin-Leclercq","sequence":"additional","affiliation":[{"name":"GNOS Research Group, Louvain Drug Research Institute, Universit\u00e9 catholique de Louvain, UCLouvain, 1200 Bruxelles, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,3,23]]},"reference":[{"key":"ref_1","unstructured":"Centers for Disease Control and Prevention (CDC) (2019, January 23).
