The most adaptable grape variety of those previously imported to Primorsky Krai was the Alpha variety, which demonstrated high frost tolerance and was resistant to various fungal diseases. An industrial viticulture based on this grape variety began in the region. The Alpha variety is an interspecies hybrid produced by natural hybridization of the two varieties Vitis labrusca L. and V. riparia Michx., the physical origin of which was the state of Minnesota (USA) [7]. Each grape variety is known to be characterized by its own polyphenol composition [8]. Therefore, the goal of the present work was to isolate and establish the structures of the main oligomeric stilbenes from stems of the Alpha variety collected in southern Primorsky Krai of the Russian Federation and to study their antioxidant properties. An herbarium specimen of the Alpha variety (voucher No. 267600) was located in the bioresource collection of FSR of Agricultural Biotechnology of the Far East named after A. K. Chaiki.
