| Abstract: | The occurrence of iridoids from 16 VERBASCUM species was investigated. The negative ion mass spectroscopy of the acetylated compounds was very useful concerning the appearance of a molecular ion. The fragmentation behaviour of the iridoids under positive and negative ionization is compared and discussed. |
