Abstract
The air-dried stems and branches of Rauvolfia tetraphylla afforded a new labdane diterpene characterised as 3β-hydroxy-labda-8(17),13(14)-dien-12(15)-olide on the basis of spectroscopic studies including UV, IR, MS and NMR (1H, 13C and HMQC); this is the first report of a new terpenoid constituent from R. tetraphylla, an important medicinal plant widely known for the source of a variety of alkaloids.
