In the present study, we investigated the volatile-flavor compounds in barks of Prunus sargentii and physiological activity of benzaldehyde, main compound of the volatiles. The volatile compounds analyses was performed by gas chromatography with mass selective detector after simultaneous distillation extraction (SDE). As a results, yield of SDE extract was 0.0241%, and fourteen compounds were identified. The principal compounds of the volatiles in SDE extract from barks of P. sargentii are benzaldehyde (34.592%), hexanoic acid (22.863%), hexanal (10.736%), anethole (6.958%), (-)-menthol (5.964%), 2-amylfuran (5.368%). Moreover, piperitone, coumarin, benzyl alcohol, ethylacetate, 1-pentanol, methyl hexanoic acid, 2,4-decadienal and α-isomenthone were identified as small and trace compounds. In antibacterial activity by the disc diffusion assay, benzaldehyde showed antibacterial activity against Staphylococcus aureus , Staphylococcus epidermidis and Pseudomonas aeruginosa . Moreover, benzaldehyde showed dosedependent nitric oxide (NO) production inhibitory effect in lipopolysaccharide (LPS)-stimulated RAW 264.7 cell. As a result, the volatile-flavor compounds in barks of P. sargentii could be applicable to cosmetic and fragrance industry.
