CARVONE AND DILLAPIOLE CONTENT OF DILL FRUITS BY GAS CHROMATOGRAPHY WITHOUT PRELIMINARY DISTILLATION

Cold hexane extracts of sixteen specimens of dried dill fruit were examined for their content of carvone and dillapiole by gas chromatography. Dillapiole was absent from “European dill” (even Indian grown), and present in “Indian dill” (including European grown) in about twice the weight of carvone. These two forms of dill are otherwise less distinct than the forms of fennel which are referred to one species. 1969 Royal Pharmaceutical Society of Great Britain
