Chilean euphorbiaceae species as sources of fuels and raw chemicals

The potential of some species of Chilean Euphorbiaceae as sources of hydrocarbon-like materials was evaluated. Samples of plants excluding roots, were analyzed for CH₂Cl₂ extractives, resins and hydrocarbons. The presence of waxes and natural rubber (cis-1,4-polyisoprene) was confirmed using spectroscopic and chromatographic methods. C/H values for representative fractions were calculated and extracted samples from selected species analyzed for apparent protein contents. Results suggested that at least two species, Euphorbia lactiflua and Euphorbia copiapina might have an industrial potential.
