영문 초록

This study investigates the antibacterial and antioxidant activities of the ethanol extract of Acer tegmentosum Maxim (EATM) against Staphylococcus aureus. The total polyphenol and flavonoid content, 1,1-diphenyl-2- picryl hydrazyl (DPPH) and 2,2’-Azino-bis(3-ethylbenzothiazoline- 6-sulfonic acid) diammonium salt (ABTS) radical scavenging effect, and reducing power of the ferric reducing antioxidant power (FRAP) method were measured to verify the antioxidant activity of the EATM. The antibacterial activity against S. aureus using the EATM was verified by the paper disc method, minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC) methods. The total polyphenol and flavonoid contents were 266.66 μg GAE/mg and 6.46 μg QE/mg, respectively. The DPPH and ABTS radical scavenging activity showed a concentration-dependent scavenging activity. The RC50 values of the EATM were 21.49 and 12.81 μg/mL, respectively. A FRAP analysis was conducted for evaluating the reducing power of the EATM and an efficacy of 0.73 ± 0.19 mM FeSO4 E/mg was observed. The antibacterial activity of EATM against S. aureus, determined using the paper disc method, showed an inhibitory ring of 3 mm at 2 mg. The MIC was confirmed at a concentration of ≥ 16 mg/mL, while the MBC was confirmed at 32 mg/mL. As the EATM shows antioxidant and antibacterial activities against S. aureus, it can be used as an effective antidote against atopic dermatitis.
