Introduction: Cuban population to treat the fever usually uses leaves from Croton linearis Jacq., but there is almost no information about this plant; that’s why in the present work we accomplish a phytochemical study of C. linearis leaves. Material and Methods: By hydrodistillation-cohobation method, the essential oils were extracted to be characterized by Gas Chromatography – Mass Spectrometry. The non volatile compounds were separated by thin layer chromatography and colum chromatography. The isolated compounds were characterized by Nuclear Magnetic Resonance 1D (1H and 13C NMR), 2D (1H–H COSY, HMQC and HMBC); UV-visible spectroscopy and Mass Spectrometry. Results: Essential oil extraction yield 1.6% being identified 82 compounds with guaiol (7.93%), eudesma-4(15),7-dien-1β-ol (4.94%), guaia-3,10(14)-dien-11-ol (4.52%), selin-4(15),7(11)-diene (4.19%) y el β-elemene (4.13%) as the main constituents. Additionally, seven metabolites were identified as 5-hydroxy-3,7,4′-trimethoxyflavone, tetracosane, hexacosan-1-ol, 2-methyl-2-docosanol, as well as the acids oleic, stearic and the 5,8-dien-tetradecanoic. Conclusions: A total of 89 new compounds for this plant was reported, giving it a great pharmacological potentiality.
