Sinalexin, a phytoalexin from white mustard elicited by destruxin B and Alternaria brassicae.

摘要

Determination of the structure of sinalexin, a phytoalexin produced by white mustard (Sinapis alba) under biotic or abiotic elicitation, is described. Additionally, the isolation and synthesis of 4-hydroxy-benzylisothiocyanate, the major antifungalcomponent isolated from extracts of white mustard, and optimized conditions for the isolation of the phytotoxin destruxin B are described.
