Coumarins are pharmacologically active and have been used in the treatment of a diverse range of diseases. The great diversity of coumarin structures and their wide range of polarities present special problems for their simultaneous analysis. The separation of seven closely related coumarins by CZE was studied. Optimized conditions tallied with a 200 mM boric acid—50 mM tetraborate buffer pH 8.5 and were applied to the determination of coumarins in extracts from roots and aerial parts from the plant Chrysanthemum segetum. Baseline separation of six coumarins was achieved in 10 min.

The thioether (LXXIV) occurs naturally in Chrysanthemum segetum L., along with the diacetylene (LXXV). When synthetic LXXV labelled in the carbonyl carbon was fed to this plant, the active thioether was obtained in which practically all of the radioactivity of the molecule was in the carbonyl carbon. (Bohlmann, Hinz, Seyberlich and Repplinger, 1964).
