섬쑥부쟁이(Aster glehni Fr. Schm.) 분획물의 미백 및 주름 개선 효과

국문 초록 (Abstract)

천연의 식물과 추출물은 비용의 효율성과 풍부한 자원을 이점으로 식품, 약, 의약 분야와 마찬가지로 화장품 분야에서도 이용될 수 있다. 현재까지 섬쑥부쟁이는 항산화 활성을 제외하고는 그 효능에 대해 알려진 바가 없다. 따라서 본 연구에서는 울릉도의 대표적인 특산 식물인 섬쑥부쟁이 추출물을 이용하여 화장품 분야에서의 활용 방안에 대한 연구를 조사한바, 효소적 in vitro 검색법을 측정하여 이들 중 가장 우수한 EtOAc 추출물을 대상으로 이러한 저해능이 멜라닌 생성에 관련된 단백질 발현과도 연관성이 있는지를 확인하기 위해 B16F10 melanoma cell line 내 단백질 수준을 확인하였다. Tyrosinase, TRP-1의 항체를 이용한 western blot으로 관련 단백질의 발현량을 조사한 결과 섬쑥부쟁이 에틸아세테이트 분획물 100 ㎍/㎖을 처리한 군에서는 tyrosinase protein을 30.5%를 억제하였고, TRP-1은 41.5% 억제하였다. 한편, 섬쑥부쟁이 분획물의 생육 저해환 측정에서는 Staphylococcus epidermidis, Propionibacterium acnes, Escherichia coli에 대하여 헥산 분획물 2 ㎎/disc에서 각각 21.0 ㎜, 12.0 ㎜, 14.0 mm의 저해환을 나타내어 섬쑥부쟁이 헥산 분획물만이 유일하게 높은 항균활성을 나타났다. 이들 실험 결과를 미루어보아, 섬쑥부쟁이의 화장품 분야에서의 활용적 가치가 충분하다고 사료되나, 그 활성 성분에 대한 명확한 규명을 위한 추가적인 연구를 제시하는 바이다.

Plants and their extracts can be utilized as inexpensive and rich resources of active constituents in the cosmetic field, as well as the food, pharmaceutical and medicinal fields. Until now, Aster glehni Fr. Schm. had no known active effect, except on anti-oxidation, that was found during investigations for application in the cosmetic field. In this study, we examined the inhibition of enzymatic reactions to protein levels in inclusive B16F10 melanoma cell lines. Significant inhibition of enzymatic reactions was observed in the EtOAc extract, which advanced to tyrosinase protein and TRP-1 in the B16F10 melanoma cell line. These results indicated that the effect of EtOAc extract inhibited expressions of tyrosinase protein and TRP-1 in the B16F10 melanoma cell line by 30.5% and 41.5% at 100㎍/㎖ respectively. On the other hand, antimicrobial activity was evaluated to the four fractions in normal flora of the skin. Hexane extract was only exhibited in the higher clear zone in all strains. In conclusion, any cosmeceutical effects of Aster glehni Fr. Schm. may have a potential meaning, as well as possible value for further studies regarding the effects of chemical constituents of Aster glehni Fr. Schm.
