Rowan fruit is widely used in Russia as a stock for pharmaceutical and food industries. The only officinal species which fruits are harvested for pharmaceuticals is  Sorbus aucuparia L . In the Far East it is substituted by the vicarious species of rowan  Sorbus amurensis Koehne . The paper presents data on discriminating the fruits of both species of rowan based on macroscopic and microscopic identification, and on the content of biologically active compounds. The studies have proved no fundamental difference between the species. It was shown that there is no significant difference in the average values of ascorbic acid, organic acids and oxidizable substances in representative fruits samples of both rowans. The average content of flavonoids and hydroxycoric acids is reliably higher in the fruits of  S. amurensis Koehne , although incidentally. It is shown that  S. amurensis Koehne  is not inferior to  S. aucuparia  L .in its main characteristics and can be considered a promising species to be used in the pharmaceutical and food industries along with the officinal species of rowan.
