Coptis chinensis has been used in the treatment of various diseases such as soothing, anti-inflammation, antimicrobial and antipyretic in oriental traditional medicine. In this study, we investigated the effect of hot water extract of Coptis chinensis(CCW) on skin barrier and inflammation-related factors in UVB and TNF-α/IFN-γ-induced HaCaT cells and evaluated its potential as a moisturizing and anti-inflammatory material. Based on result, the amount of HA (Hyaluronic acid) production and protein and mRNA expression of filaggrin were measured. In TNF-α/IFN-γ-induced HaCaT cells, CCW increased the amount of HA production in a concentration-dependent manner. In the measurement of protein and mRNA expression of filaggrin, the expression rate increased as the concentration of CCW increased. In UVB-induced HaCaT cells, CCW decreased the production of ROS and showed significant results with EGCG ((-)-epigallocatechin-3-gallate), a positive control. In addition, CCW inhibited the expression of inflammatory cytokines TNF-α, IL-1β, IL-6, and IL-8 in TNF-α/IFN-γ-induced HaCaT cells. It was confirmed that the protein and mRNA expression of COX-2, a major factor in skin inflammation, was decreased in a concentration-dependent manner. These results suggest that hot water extract from Coptis chinensis can be used as a cosmetic material having a moisturizing and anti-inflammatory effect.

황련은 한의학에서 진정, 소염, 항균 및 해열 등의 여러 질병의 치료에 이용되어져 왔다. 본 연구에서는 UVB와 TNF-α/IFN-γ로 유도된 HaCaT 세포에서 피부장벽과 염증관련 인자에 대한 황련 열수 추출물(CCW)의 효과를 조사하고, 보습 및 항염증 소재로서의 가능성을 알아보고자 하였다. 각 질형성세포인 HaCaT 세포에서 CCW의 보습 및 항염 효과를 확인하기 위해 MTT assay를 통한 시료의 독성 평가를 실시하였다. 이를 바탕으로, HA(Hyaluronic acid) 생성량과 filaggrin의 protein 및 mRNA 발현을 측정하였다. TNF-α/IFN-γ로 자극된 HaCaT 세포에서 CCW는 농도 의존적으로 HA의 생성량을 증가 시켰고, filaggrin의 protein 및 mRNA 발현 측정 결과 CCW의 농도 증가에 따라 발현율도 증가하였다. UVB로 유도된 HaCaT 세포에서 CCW는 ROS의 생성을 감소 시켰고, 양성대조군(positive control)인 EGCG( (-)-epigallocatechin-3-gallate)와 유의한 결과를 보여 주었다. 또한, CCW는 염증성 사이토카인 TNF-α, IL-1β, IL-6, IL-8의 발현을 억제 시켰고, TNF-α/IFN-γ로 자극된 HaCaT 세포에서 피부 염증에 따른 주요 인자인 COX-2의 protein 및 mRNA 발현이 농도 의존적으로 감소되는 것을 확인할 수 있었다. 이러한 결과는, 황련 열수 추출물의 보습 및 항염증 효과를 가지는 화장품 소재로서의 가치를 제안할 수 있다.
