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 $mu extrm{g}$/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 $mu extrm{g}$/mL SLS와 자외선 B 30 mJ/$ extrm{cm}^2$로 조사했을 때, IL-1$alpha$ 및 TNF $alpha$의 생합성 역시 1 $mu extrm{g}$/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 $mu extrm{g}$/mL parsley extract treatment. The producions of PGE$_2$ induced by UVB irradiation were decreased 60％ after 1 $mu extrm{g}$/mL parsley extract treatment. The treatment with 1 $mu extrm{g}$/mL parsley extract also decreased the synthesis of IL -1 ${alpha}$ and TNF ${alpha}$ induced by 10 uM RA, 100 $mu extrm{g}$/mL SLS and 30 mJ/$ extrm{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.
