Myoporum bontioides is a folk medicinal plant from the northwest of China a
nd is known as a superficies-syndrome drug. The EtOH extract from the dried
root of Myoporum bontioides was chromatographed to give furanoeudesmane-B,
a new eudesmane sesquiterpenoid. The structure of furanoeudesmane-B (3 bet
a -angloyloxy-4 alpha -acetoxy-5 alphaH-furanoeudesmane), C22H30O5, has not
been determined by X-ray crystallography before.
