| Popis: | Comparative investigation of hydro-distilled essential oils from leaves and flowers of Callistemon viridiflorous Sims (family Myrtaceae) grown in Egypt was carried out including their chemical composition and some of their bioactivities. The obtained oils revealed the presence of 19 and 22 identified constituents in the leaves and flowers, respectively. The oils were dominated by oxygenated compounds of 96.1 and 98.5 % in leaves and flowers of C. viridiflorous respectively. Methyl eugenol was found to be the main component in leaves (89.1 %) and flowers (95.1 %). Hydrocarbon contents in both leaves and flowers were 3.9 and 1.5 %, respectively. The unsaponifiable fraction of the fixed oil obtained by extracting the leaves of C. viridiflorous with petroleum ether was analyzed by GLC. The percentage of hydrocarbons and sterols were found to be 76.9 and 2.9 %, respectively. Nonane (12.0 %), octadecane (11.0 %) and hexane (9.1 %) were found as the major hydrocarbon constituents. Stigmasterol (1.3 %), β... |
