도서관이 알아야 할 출판과 책 이야기 - 책을 만드는 것은 어떤 일인가
한미화,Han, Mi-Hwa 한국도서관협회 2005 圖協會報 Vol.46 No.3
도서관문화 2004년 4월호를 시작으로 '도서관이 알아야 할 출판과 책 이야기' 코너를 집필해오던 한미화 출판칼럼니스트의 글은 이번호로 끝마칩니다. 5월호부터는 이 코너를 최성일(출판평론가) 씨와 김준목(인문학 교양잡지 <안띠꾸스> 주간) 씨가 꾸려가게 됩니다. 두 분의 글은 2006년 12월까지 게재되는데, 김준목씨의 글은 분기별(3,6,9,12월)로 1회씩 총 8회가 실리게 됩니다.

The ethanolic extracts of Inula Flos (IF), Chrysanthemi Flos (CSF) and Carthami Flos (CTF) were carried out to investigate the anti-wrinkle and antioxidative effects as part of the development of natural cosmetics materials. Total polyphenol content in CTF (134.71 mg/g) and total flavonoid content in IF (79.38 mg/g) were higher than those of other ethanolic extracts. The collagenase and elastase inhibition rate for anti-wrinkle effect showed 34.06% and 54.09% in the IF, respectively, at the concentration of 2.0 mg/mL. The tyrosinase inhibition of CTF was 19.67% at 2.0 mg/mL. IF at a concentration of 2.0 mg/mL was the highest xanthine oxidase inhibition effect of 43.81%. The electron donating ability of IF was 93.43% at 2.0 mg/mL, especially IF was over 80% at 0.1 mg/mL. In the analysis of nitrite scavenging activity, CSF (97.17%) and CTF (98.44%) showed a significantly higher effect than ascorbic acid (95.21%) at the condition of pH 1.2 and 2.0 mg/mL. At the condition of pH 3.0, CTF was 94.49% at the concentration of 2.0 mg/mL. The SOD-like activity of IF was 90.85%, and that was 4.2 times to 6.2 times greater than CSF and CTF. These results suggest that the CTF was rich in total polyphenol content and nitrite scavenging activity was better than other extracts. IF showed relatively higher effect of collagenase and elastase inhibition than the CSF and CTF ethanolic extracts, and its electron donating ability and SOD like activity were over the 90% rate. These results suggest that the IF is a potentially useful anti-wrinkle and antioxidant source for the development of functional cosmetic.

Collagenase와 elastase 저해율은 2.0mg/mL에서 선복화 에탄올 추출물이 각각 34.06%와 54.09%로 가장 우수한 저해율을 보였으며, tyrosinase 저해율은 홍화에서 19.67%을 나타내었다. 선복화는 2.0 mg/mL에서 43.81%의 xanthine oxidase 저해활성을 나타내었으며, 전자공여능은 93.43%로 0.1 mg/mL에서도 80% 이상의 활성을 나타내었다. 아질산염 소거능은 pH 1.2의 2.0 mg/mL의 조건에서 감국과 홍화가 각각 97.17%와 98.44%으로 대조군인 ascorbic acid(95.21%)보다 높은 아질산염 소거율을 보였으며, 홍화는 pH 3.0에서도 94.49%의 아질산염 소거능을 나타내었다. SOD 유사활성능은 선복화가 90.85%로 대조군(95.56%)보다는 낮았으나 감국과 홍화보다는 4.2∼6.2배 높은 활성을 나타내었다. 이상의 결과, 홍화는 폴리페놀을 다량 함유하며, 아질산염 소거율이 우수하였으며, 선복화는 감국과 홍화보다 우수한 collagenase와 elastase 저해율을 보였으며, 90% 이상의 전자공여능과 SOD 유사활성능을 나타내므로 항주름 및 항산화 효과를 가지는 기능성 화장품 소재로서 활용 가능할 것으로 판단된다.
