The biosynthetic route for epoxyangelate esters of the sesquiterpene lactones (STL) uvedalin and enhydrin from in vitro cultures of Smallanthus sonchifolius (Asteraceae) was investigated with C-13-precursors for the first time in the literature. Photomicroscope analyses and studies using MALDI-MS imaging confirmed that glandular trichomes accumulate STL.
