V. amurensis is the world’s most northerly grapevine species that originates in the exceptionally
cold climate in northeast China, and many V. amurensis grapes have been widely used because
of not only their strong cold tolerance and disease hardness, but also high pigment content.
However, until now it remains no detailed description of the anthocyanin composition and
content in V. amurensis grapes. In this study, anthocyanin profiles in the berry skins of five V.
amurensis grapes and one hybrid cultivar were analyzed by high performance liquid
chromatography-electronic spray ionization-tandem mass (HPLC-ESI-MS/MS). The result
showed that both the V. amurensis grapes and the hybrid cultivar contained 3,5-diglucosides of
anthocyanidins with high amount in addition to 3-monoglucosides of delphinidin, cyanidin,
petunidin, peonidin and malvidin that are generally detected in V. vinifera grapes. Furthermore,
pelargonidin-3, 5-diglucoside and B-type vitisins of some anthocyanidin-3-glucosides were also
identified in trace amount and no acetylated anthocyanins were detected in these samples. This
finding will be important to utilize this germplasm resource in grapevine breeding programs and
to further uncover biosynthesis and regulation of anthocyanins in V. amurensis grapes.
