Fixed and volatile constituents of genus croton plants: C. adenocalyx baill - Euphorbiaceae

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).
