| Summary: | The essential oils from various parts of Lilsea nidularis, Lilsea resinosa, Cinnamomum javanicum and
Cinnamomum microphyllum (Lauraceae) was extracted using hydrodistillation method. The essential oils
obtained were analyzed using Gas Chromatography Mass Spectrometry (GC-MS). The percentage of essential
oil extracted from two Lilsea spp ranged from 0.5% to 1.5% (v/w). The percentage of essential oils from two
Cinnamomum spp. ranged from 1.20% to 8.12%. The highest yeild of oils was obtained from the roots of C.
javanicum(8.12%) and lowest oils obtained from the barks of C. microphyllum (1.20%). The root oil and the
leaves oil of L. resinosa was rich in (Z, E) - a-famesene (12.40%) and cadina-3, 9-diene (27.11 %). Elixene was
the highest composition compound in the bark oil of L. nidularis with 9.17% compared to the leaves oil which
was rich in selina-6-en-4-o1 (20.62%). The bark, leaves and root oil of of C. javanicum was rich in I-Isopropyl-4,
8-dimethylspiro [4.5] dec-8-en-7-one (18.97%), 3,5-Diisopropylphenol (12.79%) and eugenol methyl ether
(23 .67%) respectively. The leaves oil of C. microphyllum was rich in longipinocarveol (18.48%) while the bark
oil of C. microphyllum was rich in 6-Isopropenyl-4, 8a-dimethyldecahydro-I-naphthalenol (22.29%). Toxicity
test against brine shrimp Artemia salina showed that some of the essential oil from Lilsea spp. and Cinnamomllm
spp. were toxic. The leaves oil ofL. nidularis and bark oil of C. javanicllm showed the highest toxicity with LCso
less than 101lg/mL which showed 100% mortality at concentration of 101lg/mL. |
