Objective: comparative determination of glycoside of amygdalin in kernels of stone fruits of Rosaceae family growing in southern districts of Primorskiy territory. Methods: We used fruits of Prunus padus and Prunus maackii, apricots, plums and cherries of different species, and we used their kernels to make an extract with 95 % ethanol using simple maceration. We performed spectrophotometry, liquid chromatography and mass-spectroscopy to examine extracts. Results: Due to combination of physical and chemical parameters amygdaline was identified in extracts of kernels of bird cherry fruits. Its highest content was detected in kernels of Prunus maackii fruits. Intervarietal differences of glycoside content over the species range were insignificant. The content of amygdalin in kernels of Prunus maackii was 16-18 % lower than in bitter almonds, however kernels of this bird cherry fruits have much less ballast substances that simplifies manufacturing technology. Conclusions: Kernels of Prunus maackii fruits are similar to bitter almond in amygdalin content and are show promise as raw materials resource to produce herbal medicinal products of amygdalin.
