ABSTRACT: Campomanesia adamantium is a native fruit species of the Cerrado and is used in food and medicines and as bee pasture. The chemical composition of essential oils obtained from plants of the same species have varying constituent proportions due to the influence of extractive factors, environmental, genetic and ontogenetic. This study aimed to identify the influence of hydrodistillation time on the content and chemical composition of essential oil extracted from the leaves of C. adamantium . Treatments consisted of five extraction times (1, 2, 3, 4, and 5h) using Clevenger with five replications in a completely randomized design. It was observed that after two hours of hydrodistillation, the essential oil content remains constant. Regarding the chemical constituents of essential oil, variation of the proportions of the compounds tested occurred at all hydrodistillation times. The compounds spathulenol oxygenated sesquiterpenes and caryophyllene oxide were the majority in the five hydrodistillation times.

Trout taken from deep waters of Lake Superior are of two subspecies—a fat one and a lean one—that vary greatly from each other in physical characteristics and in chemical composition. The fat species has a smaller head, larger body, and lighter colour. The percentage of oil does not reach 20% in the fillets of the lean species, whereas it may reach 67% in fillets of the fat species, which has the highest known oil content of any fish.

Thirty-five mint accessions were evaluated during 1993 for agronomic characteristics (leaf texture, color, and pubescence), plant vigor, cold hardiness, insect population interactions, and contents of essential oils, ash, and total protein. These accessions were obtained from National Clonal Germplasm Repository, Corvallis, Oregon during 1992. The rhizomes were planted in the greenhouse on April 2, 1992 and transplanted to the field on May 29, 1992 as a randomized complete block design with three replications. The chemical composition data from whole plants indicated that ash content was dependent upon location from which an accession was collected, ploidy level (diploid vs. polyploid), type of mint (peppermint vs. spearmint), and genetics (hybrid vs. non-hybrid). Diploid accessions had significantly higher essential oil content. The protein content was higher in peppermint types than spearmint types. The hybrid accessions had lower protein content in comparison to non-hybrids.

The chemical composition of the hydrodistilled essential oils of four Salvia spp. were analysed by GCMS. Three of them (Salvia aramiensis Rech. fil., Salvia fruticosa Mill., Salvia tomentosa Mill.) analyzed in this study grow naturally in the Hatay flora. On the other hand, S. aramiensis is an endemic plant in Hatay flora. Fourth species (Salvia officinalis L.) is not growing in the flora of Turkey, but is only cultivated. The highest essential oil content (5.31%) was found in S. aramiensis and the least 1.68% was detected in S. officinalis. Eucalyptol was the main constituent for S. aramiensis, S. fruticosa and S. tomentosa. While this component was 58.65% in S. aramiensis, it was determined as 44.70 and 34.97% in S. tomentosa and S. fruticosa, respectively. In S. officinalis, the main constituent was determined as δ-Thujone (33.83%) and camphor (21.46%). Eucalyptol has been identified as the main composition in sage species which is grown in flora.

Essential Oil Yield

ABSTRACT: Pogostemon cablin (Blanco) Benth. is an aromatic species popularly known as patchouli. The essential oil rich in patchoulol extracted from leaves is used by the pharmaceutical industries. The objective was to investigate the effects of shade nets and shading intensities on P. cablin growth, anatomy, chemical composition and essential oil content. The experiment was conducted with two types of shade nets (black and Aluminet), three light intensities (30, 50, and 70% shading) and full sun. The different light intensities influenced the growth and the essential oil yield, and chemical composition. Patchouli plants grown in an environment with shading showed higher values for the leaf, stem, root ant total dry weights compared to full sun. At 50% of shading, Aluminet provided gain in stem and total dry weights. Aluminet and black net at 50 and 70% of shading enhance essential oil yield. Patchoulol and pogostol contents were higher under full sun, and, black net and Aluminet at 50% shading. The environment for patchouli cultivation can be improved by use shade nets, especially with Aluminet at 50% of shading.
