   <abstract xml:lang="ru">
    <p>С помощью микроспектрофлуориметра/микроспектрофотометра МCФ-15 (ЛОМО, Санкт-Петербург) получены спектры флуоресценции и поглощения интактных клеток растений можжевельника высокого Juniperus excelsа, зопника клубненосного Phlomis tuberosa. белокопытника ложного Petasites spurius, василька шероховатого Centaurea scabiosa и купыря лесного Anthriscus sylvestris. Полученные спектры собственной флуоресценции и поглощения дали возможность тестировать состав соединений снаружи клеточной стенки. Эта аппаратура позволила обнаружить на поверхности интактных клеток присутствие секретов, включающих вторичные метаболиты с максимумами флуоресценции в области 530-550 нм, характерными для фенольных соединений. В спектрах поглощения листьев обнаружены максимумы в области 580-620 нм, что свойственно голубым пигментам азуленам. Присутствие азуленов на поверхности клеток подтверждено кратковременной экстракцией этих пигментов этанолом или ацетоном. Подобный методический подход рекомендован для экспресс-анализа интактных поверхностей растительных клеток.</p>

    <p>The fluorescence and absorbance spectra of intact plant leaf cells from juniper Juniperus excelsa, Jerusalem-sage Phlomis tuberosa, butterbur Petasites spurius, centaury Centaurea scabiosa and wild chervil Anthriscus sylvestris have been obtained using the microspectrofluorimeter/ microspectrophotometer MSF-15 (LOMO, St. Petersburg). The obtained spectra of autofluorescence and absorbance made it possible to test the composition of compounds outside the cell wall. This tool is able to detect the presence of secretions on the surface of intact cells, including secondary metabolites with the fluorescence maxima in the region of 530-550 nm, characteristic of phenolic compounds. In the absorbance spectra of leaves, maxima were found in the region of 580-620 nm, which is peculiar to blue pigments azulenes. The presence of azulenes on the surface of cells has been confirmed by short-term extraction of these pigments with ethanol or acetone. Similar methodical approach has been recommended for rapid analysis of intact surfaces of plant cells.</p>
