Abstract

The products of thermal degradation of gingerols, the pungent component of the spice ginger under gas chromatographic conditions have been re-examined. Besides breakdown to zingerone and aldehydes, substantial dehydration of gingerols to shogaols has been established by improved gas chromatographic separation. The identity of the pungent and poorly pungent homologues have been clearly established as (6)- and (8)-, and (10)-gingerols/shogaols resp. Programmed temp. gas chromatography combined with TLC separation has provided a method for determining the ratio of the homologues and a possible method for estimation of gingerols and shogaols in ginger oleoresin.
