전나무 부산물 추출물의 항산화 및 항박테리아 활성성은수

초록

Background: The extract of Abies holophylla is used as an ingredient in cosmetics. This study assessed the antioxidant and antibacterial activities of the material remaining after the extract is used. Methods and Results: The 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2-azinobis (3-ethyl benzothiazoline)-6-sulfonic acid (ABTS) radical scavenging abilities were assessed to determined the free radical scavenging activity. The total phenol and flavonoid contents were determined to measure the antioxidant activity. The DPPH and ABTS radical scavenging activities of the resudual extract were higher (95.61 - 99.42% and 74.26 - 77.98% in water extract respectively) than those of the positive control. In 50% EtOH extract, the total phenol content was 389.84 ㎎·GAE/㎖, and the total flavonoid was 0.15 ㎎·QE/㎖. The minimum inhibition concentration degree for antibacterial activity against Staphylococcus aureus was < 8 to < 125 ㎍/㎖ compared to that of the positive control in all extracts. The clear zone against S. aureus was found to be 12.2 ± 3.8 ㎜. Conclusions: The A. holophylla byproducts were found to have antioxidant and antibacterial activities. Therefore, the materials remaining after the A. holophylla extract is used in cosmetics has potential functional uses.
