%X GC-RI and GC-MS analysis identified 72 and 79 components in oils extracted using HD and in the volatile fractions extracted using SPME, respectively. Two types of essential oils were produced by the plant: the root oils had aliphatic compounds as the main component (87.0%-90.1%), and the aerial part oils had phenylpropanoids as the main component (43.1%-88.6%). HS-SPME analysis showed a more precise distribution of compounds in the organs studied: oxygenated aliphatic compounds were well represented in the roots (44.3%-84.0%), hydrocarbon aliphatic compounds were in the leaves and stems (22.2%-87.9%), and phenylpropanoids were in the flowers and umbels (47.9%-64.2%). Moreover, HS-SPME allowed the occurrence of isochavicol (29.6 - 34.7%) as main component in D. crinitus leaves, but it was not detected in the oils, probably because of its solubility in water.This study demonstrates that HD and HS-SPME modes could be complimentary extraction techniques in order to obtain the complete characterization of plant volatiles.Daucus is a genus belonging to the Apiaceae family and consists of about 600 species that are widely distributed around the world. D. carota (carrot) is the main species of the Daucus genus, and its cultivated form, Daucus carota ssp. sativa, is one of the most popular root vegetable crops in the world. Carrots have been reported to be endowed with medicinal properties, i.e., hypotensive, diuretic, carminative, stomachic, and antilipemic properties [1-4]. In Algeria, the Daucus genus is represented by species living in dry and uncultivated areas and, among these, D. crinitus Desf. syn. and D. meifolius Brot. are widespread along the Algerian west coast from Tlemcen to Mascara [5]. D. crinitus is characterized by the presence of many subspecies that colonize the sands and cliffs [5]. A survey conducted by herbalists identified that, in folk medicine, a drink made from the roots of D. crinitus is used in decoction to expel the placenta after childbirth, an
