Icacinol was isolated from the roots of Icacina claessensis (Icacinaceae). By X-ray diffraction analysis it was established that this new diterpene with a pimarane skeleton, corresponds to structure 4 (Scheme 1); spectroscopic properties were also di

From Icacina guesfeldtii (leaves and roots), two new diterpene-based alkaloids have been isolated and identified as icaceine ( 2 ) and De- N -methylicaceine ( 3 ). Icacine ( 1 ) occurred both in the leaves and roots. Structure determination was perfo

Icacenone was isolated from the roots of Icacina mannii . This new diterpene has a furane ring fused to a pimarane skeleton. Its structure was established by X-ray diffraction analysis. Its spectroscopic properties are also discussed.
