Abstract

The Rhodiola Sachalinensis 5 g were mixed and extracted with methanol 150 $m\ell$ at the room temperature for 12 h. The effluents were collected and grouped into the two. Un this experimental condition, the mobile phase composition were linearly changed as follows; water/methanol : 90/10 - 30/70 (vol. %, for 5 min), 30/70 - 10/90 (vol. %, for 15 min) and an analytical column (3.9 ${\times}$ 25 em, 15 $\mu\textrm{m}$ particle size, and 300 ${\AA}$ pore size) was utilized. The performance of the extracted Rhodiola Sachalinensis as a whitening agent was not favorable, so it classifies the Rhodiola Sachalinensis extractions with two fractions and collects each fraction for whitening agent assay. For the in-vivo melanin production ratio assay that used melanin-a cell in 10 ppm concentration, it was 58.6%, the first fraction of the effluents collected between 1.0 and 4.0 min, while it was 60% between 10.4 and 17.6 min for the second fraction, which were more efficient than that of arbutin, 45.6%.

홍경천 5 g과 메탄올 150 $m\ell$을 혼합하여 상온에서 12시간 추출한 시료를 체류시간에 따라 2부분으로 분류하였다. 이때의 이동상 조성은 다음과 같으며 물/메탄올; 90/10 - 30/70 (vol. %, 5분), 30/70 - 10/90 (vol.%, 15분), 분석용 컬럼 (3.9 ${\times}$ 25 cm, $C_{18}$, 15 $\mu\textrm{m}$)에 세공크기가 300 $\AA$인 충진물을 충전하여 사용하였다. 홍경천 추출물을 이용한 미백성능 측정에서는 알부틴에 비해 효율적인 결과를 얻지 못했지만, 체류 시간에 따라 2부분으로 분리하여 각 부분에 대한 미백성능 검사 결과, melanin-a를 이용하여 in-vivo에서 수행한 멜라닌 합성율 비교한 실험에서 10 ppm의 농도를 기준으로 하는 경우, 알부틴의 45.6%보다 1.0∼4.0분 동안 수집한 #1과, 10.4∼17.6분 동안 수집한 #2가 각각 58.6%, 60%로 우수하게 멜라닌 합성을 저해하는 것을 알 수 있었다.
