Living Organisms

Compounds useful for drugs, cosmetics, and food have been obtained directly or indirectly from living organisms over the years. However, there has been a renewed interest in getting useful compounds from living organisms, especially plants. Essential oils, interchangeably called volatile oils, are bioactive compounds found in minute quantities in some plants. Essential or volatile oils have been known for years to find usefulness in foods, drugs (antimicrobial, antifungal), and cosmetics. This review attempts to summarize information on the essential oil from Ficus species concerning their morphology, pharmacology, bioactivity, and application. This was achieved by gathering information on essential oils from different Ficus species. Essential oils from Ficus species are a good source of bioactive compounds for use in drug, food, and cosmetic industries. It is worthy to note that Nigerian Figs were characterized by the high presence of phytol and 6,10,14-trimethyl-2-pentadecanone, and these compounds are, therefore, seen as markers. Furthermore, this review presents numerous insights on how to best harness the different potentials of the essential oils and possibilities to be examined.

Volatile oils of Aquilaria malaccensis Benth. (Thymelaeaceae) from Malaysia were obtained by hydrodistillation and subjected to detailed GC-FID and GC/MS analyses to determine possible similarities and differences in their chemical composition in comparison with the commercial oil. A total of thirty-one compounds were identified compared with twenty-nine identified in the commercial oil. The major compounds identified were 4-phenyl-2-butanone (32.1%), jinkoh-eremol (6.5%) and α-guaiene (5.8%), while the major compounds in the commercial oil were α-guaiene (10.3%), caryophellene oxide (8.6%), and eudesmol (3.2%). The results of the present study showed that more than nine sesquiterpene hydrocarbons were present, which is more than previously reported. Analysis also showed that the number of oxygenated sesquiterpenes in this study were much less than previously reported. Among the compounds detected were α-guaiene, β-agarofuran, α-bulnesene, jinkoh-eremol, kusunol, selina-3,11-dien-9-one, oxo-agarospirol and guaia-1(10),11-dien-15,2-olide.

Eugenia punicifolia (Kunth) D.C., Myrtaceae, known as “pedra-ume-caá”, is popularly used in the treatment of inflammation, infections, fever, flu, diabetes, and diarrhea. This study aimed to carry out a comparative study of the chemical composition of volatile oil from E. punicifolia leaves collected in Goiás and Minas Gerais, as well as to evaluate the larvicidal activity against Aedes aegypti L3 larvae, the antimicrobial activity against bacteria, pathogenic fungi, and environmental, and cytotoxic activity to Balb 3T3 cells (murine fibroblasts). Volatile oils were obtained by hydrodistillation in a Clevenger apparatus and analyzed by Gas Chromatography Coupled to Mass Spectrometry (CG/MS). A total of 60 compounds were identified, the main components found in the leaves of Goiás being Germacrene D, bicyclogermacrene and β-longipenene and in the leaves collected in Minas Gerais they were (Z)-caryophyllene, γ-cadinene, spathulenol, caryophyllene oxide, and α-cadinol. The larvicidal effect was moderate against Ae. aegypti, with LC50 of 85.53 µg / mL for samples from Goiás and LC50 of 91.52 µg / mL for samples from Minas Gerais. Both oils showed moderate bactericidal activity against K. rhiziphyla (ATCC 9341), M. luteus (ATCC 10240), and S. aureus (ATCC 29737). The oils from Goiás (IC50 706.7 µg / mL) and Minas Gerais (IC50 160.7 µg / mL) had a lower cytotoxic concentration than the toxic action for larvae and bacteria, evidencing a safety profile and an interesting therapeutic potential, mainly concerning to volatile oil from Goiás. Therefore, the volatile oils from E. punicifolia leaves collected in Goiás and Minas Gerais that presented moderate larvicidal activity for Ae. aegypti also presented a bactericide activity and less cytotoxicity against murine fibroblasts. This is the first study of the larvicidal, antimicrobial and cytotoxic activity of volatile oils from E. punicifolia leaves.

The essential oils from the leaf, stem-bark and twig of Terminalia mantaly were isolated by hydrodistillation. The volatile oils analysed on Gas Chromatography (GC) and Gas Chromatography – Mass Spectrometer (GC - MS). The identified constituents were twelve, twenty-three and seventeen for the leaf, stem-bark and twig and accounted for 89.57%, 95.77%, 95.92% respectively. Hexahydrofarnesylacetone (30.05%) and Z-pinane (16.71%) were the main constituents in the leaf oil and nonanal (21.16%) and heptanal (10.57%) were principal component in the stem-bark volatile oil. Xylene isomers namely, meta and para (21.98%-23.56%) were the major components of the twig with substantial amount of nonanal (13.64%).
