Extraction of the wood of Eugenia crebrinervis
has yielded ellagic acid and a triterpenoid
fraction composed of a 1 : 1 mixture of asiatic acid
and arjunolic acid. Extraction of the wood of Eugenia gustavioides
has given a mixture of triterpenoid acids (2.7 % of
the dry weight of the wood) of which crategolic acid
(c.1%) is the principal constituent; other major constituents are asiatic acid and arjunolic acid,
while oleanolic acid, ursolic
acid and 2α-hydroxyursolic acid are minor constituents.In both Eugenia species the
α-amyrin component occurs with the corresponding
β-amyrin analogue giving a mixture separable
only with difficulty; use has been made of the previously described
chlorination procedure1 to enable comparatively easy isolation of the α-amyrin component.
