COMPARATIVE ANALYSIS OF QUALITATIVE AND QUANTITATIVE COMPOSITION OF DIFFERENT KINDS OF CINNAMON BARK (CINNAMOMUM)

The qualitative and quantitative composition of four types of cinnamon bark (Cinnamomum) was studied by gas chromatography with mass spectrometric detection.Found in these samples were 72 compounds of various classes, including terpenes, aldehydes, alcohols, organic acids, coumarins, esters, catechins, vitamins, sterols, and sugars. As a result of the comparative analysis, the specific compounds were found that are characteristic for Cinnamomum zeylanicum (3-tuyen, 4 (10) -tuyen, eugenol, (-)-α-curcumen, linolenic acid and for a group of Cinnamomum burmannii, Cinnamomum loureiroi and Cinnamomum Cassia, namely, sativene, isosativene, longicyclene, β-elemen, γ-mourolen, α-mourolen, α-calacorene, syrinaldehyde, and syringol. The presence of common compounds with certain concentration variability was revealed for all four types of cinnamon. The selection of the most informative compounds allowing species differentiation of the cinnamon bark has been carried out by the method of main components. Among these, four components (eugenol, α-mourolen, syrinaldehyde and linolenic acid) and specific and 12 components, such as cinnamic aldehyde, α-fellandrene, limonene, linalool, copaene, caryophyllene, coumarin, benzyl benzoate, cinnamic acid, palmitic acid, linoleic acid, and disaccharides, have common origin. Further research will be directed toward establishing the criteria that would allow species differentiation of the cinnamon bark of Cinnamomum zeylanicum, Cinnamomum burmannii, Cinnamomum loureiroi and Cinnamomum Cassia types.
