초록

죽여 추출물의 미백 효과를 확인하기 위하여 용매와 추출방법을 달리한 6가지의 추출물을 얻어 tyrosinase 활성 억제시험을 하였다. 그 결과 메탄올로 추출한 죽여 추출물에서 tyrosinase 활성 억제 효과가 가장 우수한 것을 확인 하였다. 세포 수준에서 죽여 추출물의 melanin 생성 억제 효과를 알아보기 위해서 B16 melanoma 세포를 이용하여 MTT assay를 실시하였고, 50 ppm의 농도 까지는 세포 독성이 나타나지 않은 것을 확인하였다. 죽여 추출물에 의한 세포 내 melanin 합성 저해 효과를 측정하기 위해 melanin contents assay를 하였고, 10 ppm 추출물을 처리한 extra cellular에서는 control 대비 68%, intra cellular에서는 74% 수준으로 melanin 합성이 저해됨을 확인하였다. 이차원전기영동을 이용하여 B16 melanoma 세포의 proteome을 분석 해 본 결과, 죽여 추출물 을 투여하지 않은 대조군에서는 171개, 추출물을 투여한 것에서는 282개의 spot을 확인하였고, 120개의 spot matching 을 확인하였다. 이 중 미백에 관련된 12개의 단백질 동향분석을 통하여, 죽여 추출물이 melanin 합성 전이나 합성 중에 관련된 메커니즘에 관련하는 것을 알 수 있었다.

Inhibitory melanogenesis by Bambusae caulis in Teaniam (Phyllostaachys nigra var. henonis Stapf) was studied. Tyrosinase inhibition activities were evaluated with six different extracts. Among them the extract with methanol showed the highest tyrosinase activity inhibition. MTT assay with B16 melanoma showed that the extract was not toxic up to the concentration of 50 ppm. The melanogenesis was clearly inhibited by the extract when it was examined by the melanin content assay in the cell. When the extract was dosed as 10 ppm, the melanogenesis was reduced to 68% in culture medium and 74% in the cell. By the proteome analysis with 2-D electrophoresis, 171 protein spots were found in the control gel and 282 spots were detected in the sample gel. Among 120 spot proteins matched, 12 spots were identified as proteins involved in the melanogenesis mechanism.
