Abstract
Capsidiol, a sesquiterpene phytoalexin produced by infected pepper, wa s metabolized into three more polar products after incubation with rab bit liver microsomes. One of these was identified as 13-hydroxycapsidi ol by mass spectrometry analysis. In pepper leaves, capsidiol inhibite d in a competitive manner trans-cinnamate-4-hydroxylase activity, a cy tochrome P-450-dependent monooxygenase. The metabolism of capsidiol in pepper leaves is discussed.
