ABSTRACT
The
chemical compositions of the essential oils
obtained from six tree parts of Chrysophyllum albidum (Sapotaceae) were extracted by hydrodistillation and
analyzed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). A total of 65, 33, 45, 21, 25 and 18 compounds, representing 79.49%,
100%, 90.81%, 98.43%, 96.62% and 98.37% of the total oil, were identified in
the fruit bark, root bark, stem bark, seed bark, leaf and seed, respectively. The
dominant compounds in the essential
oils in six tree parts were m-xylene (66.7%;
seed), p-xylene (21.4%; seed bark), α-farnesene (38.1%; leaf), hexadecanoic acid
(14.7%; stem bark), m-xylene
(53.1%; root bark) and
hexadecanoic acid (12.7%; fruit bark). The essential oils were evaluated for their
antibacterial, antioxidant and insecticidal activities using Alamar blue assay,
DPPH radical scavenging activity and contact toxicity test, respectively. The
oils displayed moderate antibacterial potentials to some tested organisms and
low radical scavenging activity to DPPH. Rhyzopertha
dominica was susceptible to C. albidum stem bark essential oil only.
