| dc.description.abstract | Abstract. The objectives of this research were to isolate and determine of
essential oil content from leaf and bark of cinnamon and to separate eugenol
from cinnamomum oil using any variant of NaOH concentrations and
temperatures as well as to determine of rendement and quality of cinnamomum
oil influenced by different treatments. The research resulted that the rendement
from cinnamomum bark oil using air drying treatment was 0.8955 % and by sun
drying treatment was 0.7755 %, whereas the rendement from cinnamomum leaf
oil using air drying and sun drying treatments were 2.0040 % and 1.5445 %,
respectively. The diverse index of cinnamomum bark oil using air drying
treatment was 1.5676 and by sun drying treatment was 1.5786, whereas the
diverse index of cinnamomum leaf oil using air drying and sun drying
treatments were 1.5305 and 1.5434, respectinely. The density of cinnamomum
bark oil using air drying treatment was 1.0324 g/cm3 and by sun drying
treatment was 1.0376g/cm3, whereas the density of cinnamomum leaf oil using
air drying and sun drying treatments were 1.0290 g/cm3 and 1.0324 g/cm3,
respectively. The optical rotation of cinnamomum bark oil using air drying
treatment was +4.325 and by sun drying treatment was +5.425, whereas the
optical rotation of cinnamomum leaf oil using air drying and sun drying
treatments were +3.050 and +5.225, respectively. The solubility of
cinnamomum bark oil in 70 % alcohol using both treatments were 1 : 3, whereas
the solubility of cinnamomum leaf oil in 70 % alcohol using both treatments had
also the similar results of 1 : 1.5. The cinnamaldehide content from
cinnamomum bark oil using air drying treatment was 63.131 % and by sun
drying treatment was 61.04 %. The result of gas chromathography analysis
showed that the best treatment to obtain high eugenol content in the
cinnamomum bark was 4 % NaOH in 60o C, whereas 4 % NaOH in 45o C was
the best for oil from the cinnamomum leaf. | en_US |
