Summary: | Hydrodistillation of berries and leaves of Juniperus phoenicea grown in
Sinai yielded volatile oils in the yield of 0.36 and 1.96%,
respectively. Using gas chromatography/mass spectrometry technique,
fifty eight compounds were identified in berry oil representing 99.2%
of the oil composition. α-Pinene was the major compound in berry
oil (39.30%) followed by sabinene (24.29%). Berry oil composed mainly
of monoterpenoids which amounted to 90.53%, of which 72.85% was
monoterpene hydrocarbons. The sesquiterpenoids accounted for about 8%
of the total oil composition. Leaf oil was composed of about 66
compounds representing 99.16% of the total composition of the oil.
α-Pinene was the major constituent of leaf oil at concentration of
38.22%, followed by α -cedrol (31.23%). The monoterpene
hydrocarbon was the predominant chemical group (41.29%) followed by the
oxygenated sesquiterpenes (32.21%). Both oils showed very high
cytotoxic activities against all cell line tested. They showed equal
activities against brain (0.6 μg//ml) and cervix (5.0 μg//ml)
human cell lines, while berry oil was slightly more active than leaf
oil against lung (0.6 and 0.7 μ/ml, respectively), liver (0.7 and
0.9 μg//ml, respectively) and breast human cell lines (0.8 and 1.
μg//ml, respectively).The antimicrobial activity and minimum
inhibitory concentration (MIC) of leaf and berry oils were also
determined. The oils showed high activity against most of the tested
strains. |
