“…Table 1 contains the list of identified components, including calculated retention indices and determined volume fractions of components. In general the list of identified compounds agrees reasonably with the available results of analytical studies of ylang-ylang oil in the literature [15][16][17][18][19]. Note that we were able to identify about 30 additional compounds in comparison with previous results [18], such as pentyl acetate, sabinene, a-terpinolene, p-cymene, etc.…”

The use of the large retention index database for identification and filtering of false positive hits in GC-MS analysis of the ylang-ylang essential oil is illustrated. Differences between experimental retention indices and database values of retention indices of candidate compounds provide additional constraints on the list of candidates for a target compound. Over 100 components of ylang-ylang essential oil (total grade) were identified. The main components, with concentrations more than 4 %, are b-caryophyllene, germacrene D, benzyl benzoate, linalool, geranyl acetate, a-(E,E)-farnesene and isobornyl acetate.

“…LDA has been shown to perform well in classifying essential oils from chromatographic data 6 and the quality of soy sauce. 7 LDA, like PCA, extracts linear combinations of the data (canonical variables) but differs from PCA in that the membership of each group is given a priori and the canonical variables are chosen to have the greatest possible differences between the nominated groups.…”

Leaves were harvested from 37 trees of Eucalyptus subser. Euglobulares Blakely, E. globulus Labill., E. bicostata Maiden, Blakely and Simmonds, E. maidenii F. Muell. and E. pseudoglobulus Naudin ex Maiden, selected from six sites around Australia: both native-growing and cultivated taxa were chosen. Volatile leaf oils were isolated by vacuum distillation and analysed by GC (one tree was previously analysed by GC-MS). The conditions of distillation and analysis were maintained throughout this study. Many of the taxa contained α-pinene (1.5-19.6%), limonene (1.0-5.1%), 1,8-cineole (39.3-71.7%), p-cymene (0.2-2.0%), pinocarvone (0.1-4.2%), β-caryophyllene (0-5.5%), aromadendrene (0.9-20.3%), allo-aromadendrene (0.1-4.0%), α-terpineol (0.1-6.4%), globulol (0.1-5.5%), γ-eudesmol (0-1.8%), α-eudesmol (0.1-5.6%) and β-eudesmol (0.1-10.8%) as the main leaf oil components. The principal components analysis (PCA) and linear discriminant analysis (LDA) performed on the gas chromatograms of the 37 single trees studied revealed groupings of the taxa in approximate agreement with the results obtained from comparative morphological studies; LDA yielded four distinct groups, while PCA was not as discriminating. Nevertheless, in both cases the five pseudoglobulus trees formed distinct groups of their own. In addition, the loading factors of the PCA analysis indicated that the pseudoglobulus group was due to the presence in this taxon of large amounts of the three eudesmol oil components.

“…Many studies have been conducted to separate, identify and quantify the volatile components in YYEO through numerous instrumental analysis methods. Those studies investigated variations in compositions of YYEOs at different stages of growth, 1,9 geographical origins, parts of the flowers, extraction methods 10 and grades of the oils 6,7,11 . Furthermore, a study conducted has investigated the differences in the chemical profiles of YYEO from Comoros and Madagascar to differentiate the origins 3 .…”

Chemical composition of ylang‐ylang essential oil is affected by the geographical origins of flowers used for extraction. This study aimed to determine the compositional difference between the extra, first and third grades of ylang‐ylang essential oil from Comoro Islands and Madagascar. The oils were characterized by both gas chromatography‐mass spectrometry (GC‐MS) and gas chromatography‐flame ionization detector (GC‐FID) in conjunction with principal component analysis (PCA). A total of 124 volatile compounds were identified and quantified by GC‐MS and GC‐FID. Twenty‐two compounds that made up 85% to 90% of the oils were shortlisted to compare across grades and geographical origins. The PCA showed that the ylang‐ylang essential oils are clustered according to grade and origin based on their compositions. Analysis of variance was performed to determine the statistical significance of the differences between each compound across extra, first and third grades of ylang‐ylang essential oil from Madagascar and Comoros. The oils of Madagascar are dominating in geranyl acetate, cis‐α‐farnesene, benzyl benzoate, humulene and caryophyllene, while in those of Comoros, cinnamyl acetate, benzyl salicylate, trans‐farnesyl acetate and α‐farnesene are found to be higher. It is possible to verify the origin and grade of an unspecified source of ylang‐ylang essential oil from the biplot of the 22 compounds.
