정금나무(Vaccinium oldhami) 열매의 생리활성 및 항균활성
Abstract This study was carried out to investigate the biological activity and antimicrobial activity of Vaccinium oldhami fruit extracts. ABTS radical cation decolorization and the antioxidant protection factor (PF) of extracts as 92.7±4.1% and 3.6±1.6 PF were higher than a BHT of 200 μg/mL as 52.4±1.9% and 2.0±0.8 PF, and the TBARS of extracts was 74.4±2.9% with 200 μg/mL. The hypertension inhibitory activity of extracts from Vaccinium oldhami fruit indicated the activities of 28.6±0.6% with 200 μg/mL, and anti-gout activity was 43.3 ±0.8% with 200 μg/mL. Antimicrobial activity was found in Vaccinium oldhami fruit extracts on Helicobacter pylori, Staphylococcus epidermidis, Staphylococcus aureus, Eschericia coli and Propionebacterium acne. This activity was illustrated as 24 mm, 28 mm, 13 mm, 26 mm and 16 mm clear zones with 200 μg/mL respectively, and the elastase inhibitory activity which is related to the wrinkle cause was observed in extracts as 52.7±0.9% with 200 μg/mL.
