In this work, a comprehensive study on the chemical constituents of the aerial parts of Rosmarinus eriocalyx(Lamiaceae), an aromatic shrub traditionally consumed as a food and herbal remedy in Algeria, is presented. Thearoma proﬁle was analysed by headspace solid phase microextraction (HS-SPME) coupled with gas chromatography-mass spectrometry (GC/MS), whereas the crude extr act constituents were analyzed by1H-NMR and by highperformance liquid chromatography coupled with mass spectrometry (HPLC/MSn). Thirty-nine volatile compounds,most of them being monoterpenes, have been identiﬁed, with campho r, camphene, and a-pinene as the mostabundant constituents .1H-NMR analysis revealed the presence of phenolic compounds and betulinic acid whileHPLC/MSnallowed the identiﬁcation of glycosilated and aglyconic ﬂavonoids as well as phenylpropanoid derivatives.Some of these constituents, namely as betulinic acid, rosmanol, and cirsimaritin were reported for the ﬁrst time inR. eriocalyx.
