This study investigated the anti-inflammatory activities and cell viability of Amelanchier asiatica (A. asiatica) 70% ethanol extracts against RAW 264.7 cells induced by lipopolysaccharide (LPS). Cell toxicity test on macrophage cells (RAW 264.7) was performed by 3-[4,5-dimethyl-thiazol-2-yl]-2, 5-diphenyl-tetrazoliumbromide (MTT) assay and results showed 96% cell viability at 1,000 µg/mL concentration. Anti-inflammatory activity was examined via the inhibitory tests on the production of LPS induced NO in RAW 264.7 cells by Griess assay. The result showed that the extract inhibited NO production in concentration dependent manner. The iNOS and COX-2 protein expression inhibitory effects were confirmed by western blot and by reverse transcription-polymerase chain reaction (RT-PCR). From the former they were decreased by 84.3%, 56.2% at 500 µg/mL concentration, respectively, and from the latter decreased by 89.8%, 84.9% at 500 µg/mL, respectively. In conclusion, this study showed the anti-inflammatory effects of A. asiatica extracts. Thus, this could be applied to an anti-inflammatory agent.

In this study, methanol extract and its organic solvent fractions were prepared from Prunus davidiana (Carriere) Franch. fruit. Antioxidative activities, polyphenolic and flavonoid contents, and tyrosinase inhibitory activities were evaluated. Among the fractions, ethyl acetate fraction showed the highest antioxidative activity with IC50 values of 5.8 μg/mL and 88.1 μg/mL for DPPH radical and nitrite scavenging, respectively, which were comparable to those of ascorbic acid. Further, total flavonoid and polyphenolic contents were highest in the ethyl acetate fraction with IC50 values of 244.5 mg/g and 210.2 mg/g, respectively. IC50 values for tyrosinase inhibitory activity were 0.310 mg/mL and 0.329 mg/mL for the ethyl acetate and n-butanol fractions, respectively. Based on these results, it is suggested that the ethyl acetate fraction of Prunus davidiana (Carriere) Franch. fruit could be used as a functional material in the food and pharmaceutical industries.
