Gingerol related compounds

Ginger oleoresin should contain predominantly the aroma and pungency contributed mainly by the volatile oils, gingerols and related compounds. 

Fig. (13). Log cumulative concentration-contraction curves of gingerols and related compounds for PGp2a before ( o) and after the addition of different concentrations of S-(+)-[6]-gingerol ( ) or [6]-shogaol (A). The values represent means S.E.M. (n = 4-27). Significant differences from the control values at P<0.05 and P<0.01 by Student s range test.

The essential oil can be readily analyzed by gas liquid chromatography [5] However the pungent principles, which have been identified as a mixture of gingerols (1-111) and related compounds[6,7] are...
