Rosmarinus officinalis L. (Lamiaceae) is an aromatic plant widely popular mainly due to its uses in traditional medicine as an anti‐inflammatory, diuretic and antimicrobial, as well as in the prevention and treatment of diseases. These biological activities are mainly related to the presence of phenolic and terpenic compounds. This work reports a chemical profile analysis of extracts from leaves and calli of rosemary obtained by both pressurized liquid extraction and maceration. Chemical profiles were determined on calli extracts of 3, 6, 9, and 15 days of culture; chemical characterization and quantification of compounds was carried out using ultrahigh performance liquid chromatography‐mass spectrometry. A total of 53 metabolites were identified in callus and 47 compounds in leaf extracts, of which 25 correspond to phenolic compounds, mainly flavonoids and flavones, 13 terpenes that include phenolic terpenes and one diterpenolactone, two glycosides which correspond to 6‐O‐caffeoyl‐β‐D‐fructofuranosil‐(2→1)‐α‐D‐glucopyranoside and primulaverin, an aromatic compound identified as fenantrenone and a growth regulator 12‐hydroxy jasmonic acid. These results showed that undifferentiated rosemary cells accumulate the same compounds identified mainly in highly specialized tissues such as leaves. The plant cell culture supply the possibility of developing biotechnological processes to obtain compounds of commercial interest.
