The biodiversity of the Mediterranean basin ecosystem is the most prolific sources of plant metabolites playing a pivotal role as starting precursors for drug discovery [1]. Tunisia has nearly 2100 vascular plant species, many of which are endemic, widely used for traditional health care and still largely unexplored [2]. As a part of our contribution to the discovery of new secondary metabolites with potent biological activities [3-5], we have been interested to the chemical and biological sudies of the crude extracts of some medicinal plants from Apiaceae family. In this subject, the phytochemical investigation of the dichloromethanoic extract of Daucus virgatus, led to the isolation and identification of three new sesquiterpenoids. Their structures were elucidated by means of modern spectroscopic techniques such as 1 and 2D NMR and HR-ESIMS. All compound were evaluated for the antiproliferative effects against the melanoma cell line A375, the human breast adenocarcinoma cell line MCF- 7, and the non-tumor cell lnes HACAT (Keratinocyte). Interesting selective activities were unveiled.
