초록

본 연구는 육종용을 이용한 기능성 화장품 소재 개발을목적으로 육종용 추출물의 피부 미백 및 항노화 효능 검정을 위해 수행되었다. 육종용 추출물의 세포 생존율은B16F10 melanoma 세포를 이용하여 MTT assay를 수행하여 측정한 결과, 육종용 추출물 4 mg/ml 농도에서 90% 이상의 세포 생존율을 보였다. 육종용 추출물을 처리한B16F10 melanoma 세포를 이용하여 RT-PCR로 유전자 발현을 검정한 결과 tyrosinase, collagenase 및 elastase 유전자의 발현을 육종용 추출물 4 mg/ml 농도에서 각각 80.9%, 37.6%, 70.9% 억제 하였다. 육종용 추출물의 DPPH 라디칼 소거능 측정을 이용한 항산화 활성은 2 ~ 10 mg/ml 농도에서 70.6% ~ 82.6%로 높게 나타났다. 육종용 추출물의미백과 항노화 효과를 검정하기 위하여 육종용 추출물을2, 4, 6, 8 및 10 mg/ml 농도로 처리하여 확인하였다. 육종용 추출물의 tyrosinase 저해활성은 66.8% ~ 78.5%, elastase 저해활성은 67.6% ~ 79.3%, collagenase 저해활성은 72.3% ~ 83.6%로 각각 나타났으며, hyaluronidase 저해활성은 65.8% ~ 69.2%로 나타났다. 따라서 육종용은 피부 미백 및 노화방지를 위한 기능성 화장품 소재로 우수한 것으로 평가되며, 세포생존율과 각종 효능을 고려할 때, 육종용 추출물4 mg/ml 농도가 적정농도로 판단된다.

This study assessed the whitening and anti-aging effects of the Cistanche deserticola extract, to develop a cosmetic substance. The cell viability of the Cistanche deserticola extract was evaluated in B16F10 melanoma cells by the MTT (3-(4,5-dimethylthaiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay. The cell viability of the extract was determined to be 90% at 4mg/ml concentration. Furthermore, the tyrosinase, collagenase, and elastase mRNA expression level were measured by RT-PCR, using the Cistanche deserticola extract treated B16F10 melanoma cells. At 4 mg/ml concentration, mRNA expression level of tyrosinase, collagenase, and elastase was dramatically decreased to 80.9%, 37.6%, and 70.9%, respectively. The antioxidant activity of the Cistanche deserticola extract was determined by DPPH free radical scavenging. The DPPH free radical scavenging capacities ranged from 70.6% to 82.6%, when evaluated from 2 mg/ml to 10mg/ml concentrations. The effects of whitening and anti-aging of the Cistanche deserticola extracts were examined at 2, 4, 6, 8, and 10 mg/ml concentration. Tyrosinase activities were inhibited from 66.8% to 78.5%, elastase activities were inhibited from 67.6% to 79.3%, collagenase activities were inhibited from 72.3% to 83.6%, and hyaluronidase activities were inhibited from 65.8% to 69.2%, respectively. These data suggest that the Cistanche deserticola extract is effective in whitening and anti-aging; therefore, it is considered to be a functional cosmetic material in cosmetic products.
