Online LC-NMR measurements were used for the first time to elucidate the sesquiterpene lactone chem. of a Compositae species, Zaluzania grayana. Structure elucidation of three compds., visible in HPLC anal. of the constituents of glandular trichomes, was performed on a leaf ext. of less than a gram of dried plant tissue by means of direct coupling of the HPLC and NMR instruments. The structures could be assigned to the guaianolide zaluzanin C, a new modified guaianolide and to the 15-hydroxy deriv. of costunolide. The taxonomic relevance of the identified compds. is discussed.
