LIMA, Sidney G. De et al. Fixed and volatile constituents of genus croton plants: C. adenocalyx baill - Euphorbiaceae. Rev. latinoam. quím [online]. 2010, vol.38, n.3, pp.133-144. ISSN 0370-5943.
This work describes the phytochemical analysis of Croton adenocalyx Baill (Euphorbiaceae), a plant that is representative of the species from Ceará State (Brazil). The GC-MS analysis of the essential oil, obtained by hydrodistillation of the leaves from C. adenocalyx, allowed the identification of eleven volatile constituents; the main components were identified as α-pinene (32.63%); bicyclogermacrene (13.96%); trans-caryophyllene (10.23%); germacrene D (10.14%); β-pinene (10.11%) and β-elemene (8.31%). The chromatographic purification of the ethanolic extract from the trunk bark, allowed the isolation and identification of the 6-methoxy-7-hydroxycoumarin (1) and 3,5-dihydroxy-3,4,7-trimethoxyflavone (2).
