The bark of Acer komarovii was collected, ground, and extracted with 70% aqueous acetone to obtain concentrates. The concentrates were suspended in $H_2O$, and then successively partitioned with n-hexane, dichloromethane and ethylacetate to be freeze dried. A portion of ethylacetate fraction was chromatographed on a Sephadex LH-20 and a RP C-18 column with various aqueous MeOH-$H_2O$ (1:0, 1:1, 1:2, 1:5, 1:7, 1:9, 1:10, 3:1, and 4:1, v/v) eluents. Four compounds were isolated; (-)-epicatechin (9.6 g), procyanidin A2 (epicatechin-($4{\beta}{\rightarrow}8$, $2{\beta}{\rightarrow}O{\rightarrow}7$)-epicatechin) (1.3 g), procyanidin B2 (epicatechin-($4{\beta}{\rightarrow}8$)-epicatechin) (40.0 mg), and cinnamtannin B1 (epicatechin-($4{\beta}{\rightarrow}8$, $2{\beta}{\rightarrow}O{\rightarrow}7$)-epicatechin-($4{\beta}{\rightarrow}8$)-epicatechin) (690 mg). The analysis of the bark procyanidins showed that the basic unit constituting condensed tannins was only (-)-epicatechin. This study, for the first time, report the procyanidins of Acer komarovii bark.
