Résumé:
This work is devoted to the study of the chemical composition and the evaluation of the biological activities of essential oils
(EOs) extracted from the flowers of
Asteriscus graveolens
Forssk. plant. The EO sample was obtained by hydrodistillation
and the chemical composition analysis was performed using GC and GC/MS. The major chemical components characterizing
the EO were
cis
-chrysanthenyl acetate (44.30%) and
cis
-8-acetoxychrysanthenyl acetate (33.70%). Antioxidant activity was
determined using DPPH and Phosphomolybdenum tests. Although the EO presented a weak scavenging activity (420.16 mg/
mL), it exhibited good reducing power using the Phosphomolybdenum assay (0.28 AAEC/mg). The most important anti
-
bacterial activity was noted for
Bacillus cereus
. The oil revealed a remarkable activity against the nine fungi species tested
with percentage inhibition up to 94.12% for
Fusarium culmorum
(BTCR). More important, this work investigated for the
first time the anticancer effect of this EO on two types of cancer cell lines (human liver carcinoma and Rat pheochromocy
-
toma cell lines). The EO showed a high anticancer activity against both tumor cell lines comparing to the positive control
