Fixed and volatile constituents of Croton heliotropiifolius Kunth from Bahia-Brazil

Abstract

Essential oils from Croton heliotropiifolius Kunth roots and stems, popularly known in Bahia (Brazil) as velame or cassutinga, were obtained by hydro distillation. Fixed oil from the roots of this species was obtained by maceration in hexane. The oils were analyzed by nuclear magnetic resonance (NMR) and gas chromatography coupled with mass spectrometry (GCMS). 46 compounds were identified in the stems and 35 substances were found in the roots. The principal components oils were camphor, β-pinene, a n d α-pinene in t h e stems, and camphor, borneol, valencene, and viridiflorol in the roots. The fixed oil contained C8 to C18 fatty acids. It is the first study that reports the presence of fixed oil from the roots of this genus.
