파슬리추출물이 피부에 미치는 개선효과를 조사하기 위하여, 배양 인체 섬유아세포에서 total Collagen, type I procollagen을 각질형성세포주인 HaCaT 세포에서 prostaglandin E$_2$(PGE$_2$), interleukin l$\alpha$ (IL-l$\alpha$)와 tumor necrosis factor $\alpha$ (TNF$\alpha$)를 무모생쥐(Female albino hairless mice, Skh:hr-1)에서는 진피의 두께와 밀도를 측정하였다. 그 결과, 1 $\mu\textrm{g}$/mL 농도의 파슬리 추출물은 total collagen은 23%, type I procollagen은 18% 증가시켰고, 자외선 B에 의한 PGE$_2$의 생합성은 약 60% 정도 감소시켰다. 10uM RA, 100 $\mu\textrm{g}$/mL SLS와 자외선 B 30 mJ/$\textrm{cm}^2$로 조사했을 때, IL-1$\alpha$ 및 TNF $\alpha$의 생합성 역시 1 $\mu\textrm{g}$/mL 파슬리추출물 처리 시 감소되었다. 4일 동안 1% 파슬리추출물로 폐쇄첩포한 무모생쥐의 진피 두께는 대조군에 비해 약 1.5배 정도 두꺼워지고, 밀도도 훨씬 촘촘해졌다. 본 연구의 결과는 파슬리추출물이 피부에서 노화방지 효과 및 자극완화 효과가 있음을 시사하고 있다.
In order to investigate the beneficial effects of parsely (Petroselinurn sativum) extract on skin, we measured the synthesis of total collagen and type I procollagen in cultured normal human fibroblast (NHF), the synthesis of prostaglandin E$_2$(PCE$_2$), interleukin 1 ${\alpha}$(IL -1 ${\alpha}$) and tumor necrosis factor ${\alpha}$ (TNF ${\alpha}$) in HaCaT cell and we also measured dermal thickness and density in hairless mouse (Female albino hairless mice, Skh:hr-1). As the results, the synthesis of total collagen and type I procollagen were increased 23% and 18% respectively, after 1 $\mu\textrm{g}$/mL parsley extract treatment. The producions of PGE$_2$ induced by UVB irradiation were decreased 60% after 1 $\mu\textrm{g}$/mL parsley extract treatment. The treatment with 1 $\mu\textrm{g}$/mL parsley extract also decreased the synthesis of IL -1 ${\alpha}$ and TNF ${\alpha}$ induced by 10 uM RA, 100 $\mu\textrm{g}$/mL SLS and 30 mJ/$\textrm{cm}^2$ UVB irradiation, After 4 days treatment with 1% parsley extract, the dermal thickness of hairless mouse was increased 1.5 times and the density of dermis was tighter than control. These results indicate that parsley extract have anti-aging and anti-irritation effects on skin.
