Abstract

항산화 활성, 항염증 효과, 항균작용, 주름개선 및 미백 효과 등이 알려져 있는 연교를 함유하며, 항염증 효과를 갖는 연교승마탕(連翹升麻湯), 가미연교승마탕(加味連翹升麻湯) 및 회춘양격산(回春凉膈散) 각각의 처방단을 추출하여 항노화 관련 효능을 알아보았다. 연교처방단 추출물의 자유라디칼 및 활성산소 소거 활성, 타이로시네이즈 활성 저해효과, 최종당화산물 생성 저해효과를 알아보았으며, 콜라겐 생성 및 자외선에 의해 유도된 MMP-1 생성 저해, <TEX>${\alpha}$</TEX>-MSH에 의해 유도된 멜라닌의 생성 저해효과를 확인하였다. 그 결과 항산화 및 항당화 효과를 보였으며, 효소처리 한 연교승마탕 추출물과 가미연교승마탕 75% 에탄올수용액 추출물은 콜라겐 생성 및 MMP-1 생성 저해효과를 나타내었다. 효소처리 한 회춘양격산 추출물들은 멜라닌 생성 저해효과를 나타내었다. 이로써, 연교처방단 추출물을 이용한 항노화 소재로서의 개발 가능성을 확인하였다. Forsythia fructus has been shown to have antioxidative, anti-inflammatory, antibacterial, anti-aging and whitening effects. This work was carried out to investigate the anti-aging effects of Forsythia viridissima-prescription extracts (Yeongyoseungma-tang, Gamiyeongyoseungma-tang, Hoechunyangkyeok-san) on skin. Skin anti-aging effect of Forsythia viridissima-prescription extracts (Yeongyoseungma-tang, Gamiyeongyoseungma-tang, Hoechunyangkyeok-san) was evaluated by using antioxidant assay, anti-glycation activity, inhibitory effect of tyrosinase activity, expression of type I procollagen and UVA-induced matrix metalloproteinase-1 on HS68 cells, and reduction of <TEX>${\alpha}$</TEX>-MSH-induced melanin on B16F1 cells. Forsythia viridissima-prescription extracts showed anti-oxidative and anti-glycation activity. The pectinex hydrolysed extract from Yeongyoseungma-tang 75% EtOH extract and Gamiyeongyoseungma-tang 75% EtOH extract increased the type I procollagen synthesis, and decreased the UVA-induced MMP-1 expression on HS68 cells. The pectinex hydrolysed extracts of Hoechunyangkyeok-san 75% EtOH extract had the inhibitory effect of melanin synthesis on B16F1 cells. Based on these results, we suggest that Forsythia viridissima-prescription extracts may be useful as a potential source of functional anti-aging cosmetics.
