Abstract :
This study was conducted with the objective
of contributing to the valorization of aromatic and
medicinal plants of Côte d’Ivoire. The essential oil (EO)
of the leaves of two species of Premna, P. angolensis and
P. quadrifolia obtained through steam distillation
process, were analized through gas chromatography
coupled with mass spectroscopy (GC-MS) and their
antimicrobial activities was evaluated by agar diffusion
method. The yields of EO extracted from the leaves of
P. angolensis and P. quadrifolia are respectively 0.10 ±
0.02% and 0.40 ± 0.02%.
99.43% of the total chemical composition of the EO
of P. angolensis leaves, are composed mainly of
hydrocarbon sesquiterpenes (71.90%) followed by
oxygenates (14.16%) and monoterpenes (13.22%). The
main compounds found are β-caryophyllene (33.07%)
and Humulene (10.78%). The EO of P. quadrifofia
leaves, 99.59% of the composition was identified. It
contains hydrocarbon sesquiterpenes (89.15%),
followed by oxygenates compounds (8.61%) and
monoterpenes (1.83%). The major compounds are αbulnesene (23.33%), germacrene D (18.83%) and
caryophyllene (18.06%). The antimicrobial tests have
shown that EO of P. quadrifolia leaves has no activites
on studied strains and P. angolensis oil has a mild
activity on Staphylococcus epidermidis and Klebsielle
pneumoneae and a weak sensibility on Staphylococcus
aureus CIP 4.83 and Candida albicans ATCC 10231.
This study highlights chemical composition of the EO
from P. angolensis and P. quadrifolia leaves. It shows
more similarities of the chemical compositions of these
two species of Premna and the interesting antimicrobial
activity potential of P. angolensis EO
