Stages in the biosynthesis of [6]-gingerol in zingiber Officinale
Abstract
[2-14C,3H,3-3H]Dihydroferulic acid and [1-14C,6-3H]hexanoic acid are shown to be incorporated into (S)-[6]-gingerol in Zingiber officinale, the 3H/14C ratio falling by ½ in the first case but remaining constant in the second; a biogenetic scheme is proposed to accommodate these results, and includes discussion of the late stages of biosynthesis in the light of satisfactory incorporation of [10-3H]-[6]-dehydrogingerol (5).
