Abstract: Isolation and
characterization of triterpenoid from n-hexane fraction in Annona squamosa L
stem bark extract has been investigated. The result was obtained as a white
crystal with melting point 176.8 – 178.2 oC which has shown single spot to several eluents in
some comparisons. LB test has indicated was of the triterpenoid compound. UV
spectra of the compound has shown max absorption at 206 nm which of
non–conjugated double bond. From IR spectra analysis one can conclude that the
appearance of bands at around 3440 cm-1, 2931 cm-1, 1686
cm-1, 1372 cm-1 and 1199 cm-1 indicate the groups of –OH,
aliphatic C-H,C=O, geminaldimetil and C-O.
