“…34-22 °C). These results are in agreement with a similar study in Cymbopogon nardus (citronella) in the case of citronellal but not in the case of geraniol (Herath, Iruthanthas & Ormrod, 1979).…”

Java citronella (Cymbopogon winterianus Jowitt) is an important perennial aromatic grass cultivated in different parts of India. The steam-volatile essential oil from the citronella herb is widely used in perfumery, in manufacture of deodorants and mosquito repellent creams and in flavouring beverages. Systematic cultivation of this crop is being taken up and application of large quantities of N fertilizers was found to increase yield (Narayana et al. 1975; Bommegowda, 1978; Singh, Pathak & Bodoloi, 1980; Prakasa Rao et al. 1983). However, the efficiency of N utilization by this crop was found to be quite poor (Prakasa Rao et al. 1983). No systematic data are available in India on the effect of harvest season and N fertilizers on the principal constituents of citronella oil. Therefore the present experiment was made with two objectives: (i) to determine the effect of harvest season and N fertilizers on the essential oil concentration and the principal constituents of the oil which determine the oil quality, and (ii) to determine the effect of neem cake, an indigenous cheap material which is reported to have nitrification inhibitory properties, on the herb and essential oil yields of citronella.

“…Camphor trees have been cultivated as a crop for many decades in China to produce camphor, linalool, eucalyptol, and borneol, but we also found individual plants rich in methyl isoeugenol, methyl eugenol, or δ-selinene. Methyl isoeugenol has been reported in Cymbopogon nardus and Pimenta pseudocaryophyllus [ 42 , 43 ], while methyl eugenol has been found in Croton malambo [ 44 ], and δ-selinene has been reported in Jatropha elliptica rhizomes [ 45 ]. Although these chemotypes rarely occur in camphor trees, they are valuable for developing new essential oil products.…”

Cinnamomum camphora is a traditional aromatic plant used to produce linalool and borneol flavors in southern China; however, its leaves also contain many other unutilized essential oils. Herein, we report geographic relationships for the yield and compositional diversity of C. camphora essential oils. The essential oils of 974 individual trees from 35 populations in 13 provinces were extracted by hydrodistillation and analyzed qualitatively and quantitatively by gas chromatography-mass spectrometry and gas chromatography-flame ionization detection, respectively. Oil yields ranged from 0.01% to 3.46%, with a significantly positive correlation with latitude and a significantly negative correlation with longitude. In total, 41 compounds were identified, including 15 monoterpenoids, 24 sesquiterpenoids, and two phenylpropanoids. Essential oil compositions varied significantly among individuals and could be categorized into various chemotypes. The six main chemotypes were eucalyptol, nerolidol, camphor, linalool, selina, and mixed types. The other 17 individual plants were chemotypically rare and exhibited high levels of methyl isoeugenol, methyl eugenol, δ-selinene, or borneol. Eucalyptol-type plants had the highest average oil yield of 1.64%, followed in decreasing order by linalool-, camphor-, mixed-, selina-, and nerolidol-type plants. In addition, the five main compounds exhibited a clear geographic gradient. Eucalyptol and linalool showed a significantly positive correlation with latitude, while selina-6-en-4-ol was significantly and negatively correlated with latitude. trans-Nerolidol and selina-6-en-4-ol showed significantly positive correlations with longitude, whereas camphor was significantly and negatively correlated with longitude. Canonical correspondence analysis indicated that environmental factors could strong effect the oil yield and essential oil profile of C. camphora.

“…Sobre o eixo da primeira componente principal, pode-se observar a discriminação de um dos grupos com base na presença de monoterpenos oxigenado, com destaque para os táxons Mentha, Cymbopogon e Corimbia (Figura 2), resultados que estão de acordo com relatos previamente publicados. 11,[19][20][21][22][23][24] A segunda componente principal discriminou o gênero Ocimum, sobretudo com a contribuição de fenilpropanoides, assim como, hidrocarbonetos de monoterpenos e sesquiterpenos contribuíram para destacar o gênero Schinus (Figura 2). Estes resultados são condizentes com aqueles previamente publicados para as espécies O. basilicum [25][26][27] e O. gratissimum, 18,28 assim como, para as espécies S. molle 29,30 e S. terebinthifolius, 31,32 que apresentaram em seus óleos essenciais as referidas classes de substâncias voláteis.…”

The Botanical Garden of Federal Rural University of Rio de Janeiro (JB/UFRRJ) is an instrument for the study and conservation of native and exotic biodiversity. In addition, the JB/UFRRJ has been outstanding for promoting direct actions to encourage basic research and the development of extension activities. The collection of native and exotic plant species from JB/UFRRJ includes some plants considered aromatic, which produce essential oils with diverse applications and uses, therefore, of great academic interest. In this context, the objective was to analyze the essential oils chemical diversity obtained from JB and UFRRJ campus and to present them through a chemoarray images and multivariate analysis. Essential oils were obtained by hydrodistillation of the leaves and/or fruits of 14 plant species. Subsequently, the essential oils chemical characterization was performed by chromatography (GC-FID and GC-MS) and the chemical profile of each essential oil sample was presented as a chemoarray images. The results were submitted to principal component analysis (PCA) and hierarchical clustering analysis (HCA). The essential oils chemical analysis allowed the identification of 114 substances distributed in the studied species. It was possible to identify specific chemical markers such as menthol and carvone, as well as non-specific markers such as eugenol, citral and citronellal. General classes of volatile substances were found to group better within a taxonomic context when compared to analysis based on total composition. PCA and HCA, based on substance classes and chemical profile, outperformed taxonomic relationships.
