For the first time, we have studied the polyphenolic profile of fruits of Siberian crabapple and its hybrids (F1, F2, and F3) with domestic apple cultivated in East Siberia. It is shown that the chemical composition of polyphenolics of Siberian crabapple fruits is overwhelmingly characteristic of the genus Malus; on the other hand, it has clearly identifiable features: low content of flavan-3-ols and derivatives of cinnamic acid; high content of procyanidin B1, phloridzin, anthocyanes, and quercetin glycosides. Procyanidin B2 was not found in both peel and flesh of Siberian crabapple. In the case of hybridization with domestic apple, the fruits of resulting cultivars show a substantial change in the flavan-3-ol content ratio because of the synthesizing of procyanidin B2 in tissues and an increase in (−)-epicatechin content.
