Lutein (1), decaprenol (2a) and undecaprenol (2b) were isolated from the air dried leaves of Jatropha curcas L. Positive ion electrospray ionisation mass spectroscopy of decaprenol and undecaprenol produced a series of oxygen adduct molecular ions of general formula [CSOH820 xNat and [CSSH900xNat respectively, where x = 1 to 9. Weak dimeric oxygenated adduct ions were also observed. Electron impact mass spectroscopy produced normal molecular and fragment ions.
