Abstract :From the aerial parts of Verbascum cilicicum Boiss., 6 iridoid glycosides, namely catalpol insert ignore into journalissuearticles values(1);, verbaspinoside [= 6-O-insert ignore into journalissuearticles values(2`` -O-trans-cinnamoyl);-a-L-rhamnopyranosylcatalpol] insert ignore into journalissuearticles values(2);, 6-O-insert ignore into journalissuearticles values(3``-O-trans-cinna\-moyl);-a-L-rhamnopyranosylcatalpol insert ignore into journalissuearticles values(3);, 6-O-insert ignore into journalissuearticles values(4``-O-trans-cinnamoyl);-a -L-rhamnopyranosylcatalpol insert ignore into journalissuearticles values(4);, saccatoside [= 6-O-insert ignore into journalissuearticles values(2``-O-trans-p-coumaroyl);-a-L-rhamnopyranosylcatalpol] insert ignore into journalissuearticles values(5);, and 6-O-insert ignore into journalissuearticles values(3``-O-trans-p-coumaroyl);-a-L-rhamnopyranosylcatalpol insert ignore into journalissuearticles values(6);, were isolated. The structures of the compounds were elucidated by means of 1 and 2 dimensional insert ignore into journalissuearticles values(DQF-COSY, HMQC and HMBC); NMR techniques and LC-ESIMS.
