Fresh rhizomes of Zingiberofficinale (ginger), when subjected to steam distillation, yielded ginger oil in which curcumene was found to be the major constituent. The thermally labile zingiberene-rich fraction was obtained from its diethyl ether extract. Column chromatography of ginger oleoresin furnished a fraction from which [6]-gingerol was obtained by preparative TLC. Naturally occurring [6]-dehydroshogaol
structure determinants for antioxidant activity, we synthesized eight compounds differentiated by their sidechains which are characteristic of the C1–C2 double bond, the C4–C5 double bond or the 5-OH, and the six- or twelve-carbon unbranched alkyl chain. Our results show that their antioxidant activity depends significantly on the sidechain structure, the reaction mediums and substrates. Noticeably, existence
