The paper describes a new developed method of sample gasification using yeast oxidation of monosaccharides in plant tissue for 13 C/ 12 C isotope ratio mass spectrometric analysis. Variations in the carbon isotopic composition of the leaf surface have been shown; the δ 13 C value for chlorophytum varies from -37 ‰ to -32 ‰ from the tip of the leaf to its base. It has been shown first that the spectral composition of radiation affects the ratio of carbon isotopes in plant leaves: the predominance of blue component in the spectrum results in accumulation of heavy 13 C isotope up to δ 13 C = -25 ‰.
