Annona muricata Linn., commonly known as guyabano, is a well-known medicinal tree. The bioactivities
of A. muricata are varied, but the commonly isolated compounds are acetogenins which exhibit
anticancer properties. This study reports on the isolation of the sterols: β-sitosterone (1), β-sitosteryl
fatty acid ester (2) and β-sitosterol (3); and the triterpenes: α-amyrin (4), β-amyrin (5) and squalene (6)
from the dichloromethane extract of the freeze-dried fruit of Annona muricata Linn. Compounds 1-6 were
isolated by silica gel chromatography and identified by NMR spectroscopy. These compounds were
reported to possess diverse bioactivities.
