摘要：

A new procedure for the reliable measurement of xanthoxin from plant tissues has been developed. This accounts for both its breakdown and its isomerization to 2-trans-xanthoxin, and relies on the use of 12C-labelled internal standards, HPLC purification and analysis by GC-MS SIM. The antioxidant tert-butylated hydroxyquinoline was found to reduce the amount of isomerization to 2-trans-xanthoxin during extraction. Levels of xanthoxin present in all tissues examined were much lower than previously thought, and 2-trans-xanthoxin: xanthoxin ratios much higher. © 1990.
