-"The investigation of two commcercial concretes, one absolute and a lab-prepared concrete from the flowers of Michelia champaca L. has allowed the identification of a series of minor and trace constituents not yet know as natural products. GC/MS analysis of the concretes revealed the presence of more than 240 components. Some quantitative differences were found to exist between the components identified in the volatile part of each concrete. In the commercial absolute and concretes, the main constituents were phenylacetonitrile (1.2-4.5%), phenylethyl alcohol (25-34%), α- + β-ionone (1.0-5.0%), methyl anthranilate (2.1-9.0%), indole (2.9-12.0%) and methyl linoleate (10.0-18.0%). In contrast, the lab-prepared concrete contained linalool (11.0%), cis-linalool oxide (pyranoid, 7.0%), dihydro-β-ionone (10.0%) and α+ β-ionone (26.8%) as major constituents.\\

-Among the unusual compounds identified were 5-amyl-3,4-dimethylisoxazole, 3-amyl-4,5-dimethylisoxazole, 3-methyl-5-(2,6,6-trimethyl-cyclohex-l-en-l-yl)-isoxazole, β-ionone oxime including related oximes and two hydroquinolines possibly derived from dihydro-β-ionone oxime. Besides the oximes, some of the concretes contain many other oximes, which could have been formed by transoximation of phenylacetaldoxime with corresponding carbonyl compounds present in the same substrate. Furthermore, a series of mono and bicyclic ionone derivatives were also identified." \\

 HS-SPME analysis of floral volatiles emitted by living M.champaca flowers showed (E,E)-α-farnesene (32.7%) as main constituent, accompanied by methyl benzoate (23.4%), germacrene-D (7.3%), β-elemene (5.7%) and phenyl acetonitrile (4.6%). Indole (3.5%), zingiberene (2.1%), methyl anthranilate (1.0%) as well as (E)-α-bergamotene (1.3%) and (E)-β-ionone (0.6%) contribute to the odor of the flowers. \\

+"Odor Description: floral, exotic, rich, sweet, tea-like, fruity nuances. Champaca flower absolute is one of the most luxurious ingredients in the perfumer's palette. It's an essence with an incredibly complex and rich scent that adds depth to our compositions. The absolute opens with a strong, heady, and narcotic accent. After this intense introduction, it transitions into a beautiful phase reminiscent of exquisite jasmine tea. The scent projected at this stage is very strong, retaining a lightness while heavier notes from the opening disappear completely. In the final phase, the scent gradually fades, surprising with emerging fruity nuances."
