A new neo-clerodane diterpenoid, (13R)-1 beta-11 beta-diacetoxy-6 alph
a-hydroxy-7 beta-senecioyloxy-8 beta,13-epoxy-4(1 8)-neocleroden-15,16
-olide (Scuteselerin), has been isolated from the aerial parts of Scut
ellaria seleriana, besides the known flavone oroxylin A. The structure
of the new diterpenoid was established by spectroscopic methods. (C)
