Abstract

In this study, in order to evaluate the possibility of applying apple leaf extract as a cosmetic material, we conducted an experiment by extracting with 70% ethanol. Apple leaf extract is analyzed by GC/MS, and toxicity is evaluated through polyphenol, flavonoid content and DPPH radical scavenging activity, antioxidant, and cell viability (MTT assay) OK, and nitric oxide (NO). It was confirmed that the NO production amount decreased 4.6 times in the group treated with the apology leaf extract through the measurement of the production inhibition of), and the anti-inflammatory effect was investigated. The total polyphenol content was 78.80 ± 0.25 mg /g and the total flavonoids were 65.25 ± 6.62 mg /g. It was confirmed that the DPPH scavenging activity increased sogonun at 79.8 ± 0.99,% at an extract concentration of 0.25%, 88.13 ± 0.89% at 0.5%, and 96.83 ± 2.00% at 1%. The cell viability was evaluated at 91.19 ± 3.49% even at a high concentration of 1000 ppm, confirming a viability of 80% or more. As a result of component analysis of GC-MS, it can be used as an antioxidant cosmetic material such as catechol (5.65%), DL-Gluciol (12.05%), Ascorbic acid (2.41%), Phytol (13.88%), Hexanoic acid (5.47%). Conceivable. The result of this experiment will be used as an important basic material in the development of natural functional cosmetic materials using apple leaf extract.

본 연구는 사과 잎 추출물의 화장품 소재로 응용하기 위한 가능성을 평가하기 위하여 에탄올 70%로 추출하여 실험을 진행하였다. 사과 잎 추출물을 GC/MS로 분석하였고, 폴리페놀, 플라보노이드 함량과 DPPH radical 소거 활성을 통하여 항산화, 세포생존율(MTT assay) 확인을 통한 독성 평가를 하였으며, Nitric oxide (NO) 생성 저해 측정을 통해 사과 잎 추출물을 처리한 군에 4.6배의 NO 생성량이 감소하는 것을 확인하였고, 항염효과를 알아보았다. 총 폴리페놀 함량은 78.80 ± 0.25 mg/g, 총 플라보노이드 65.25±6.62 mg/g로 나타났다. DPPH radical 소거 활성은 추출물 농도 0.25%에서 79.8± 0.99%, 0.5%에서 88.13±0.89%, 1%에서 96.83±2.00%로 소거능이 증가함을 확인하였다. 세포생존율 평가는 고농도인 1000 ppm 농도에서도 91.19±3.49%로 80% 이상의 생존률을 확인하였다. GC-MS 성분분석 결과 catechol(5.65%), DL-Gluciol(12.05%), Ascorbicacid(2.41%), Phytol(13.88%), Hexanoic acid(5.47%) 등 항산화 화장품 소재로 활용이 사료된다. 이에 실험 결과 사과 잎 추출물을 이용한 천연 기능성 화장품 소재 개발에 있어 중요한 기초 자료로 이용되고자 한다.
