Abstract

Evaluating the antioxidant efficacy using Potentillae Chinensis Herba extract, the anti-inflammatory efficacy was tested in respiratory mucosal epithelium, RAW264.7 cells, and zebrafish. As a result, antioxidant activity increased in a concentration-dependent manner in DPPH free radical scavenging and ABTS+ cation radical activities. As a result of MTT assay for cell experiments, the survival rate of NCI-H292 cells was reduced to less than 70% when treated at each concentration of 100 ㎍/ml, subsequent experiments were conducted at 50 ㎍/ml. Anti-inflammatory efficacy evaluation, NO production, TNF-𝛼, IL-1𝛽, and PGE2 decreased, and COX-2 also decreased significantly at 50 ㎍/ml. The mucin protein expression of Potentillae Chinensis Herba extract and bioconverted extract, it was observed that MUC5AC expression was significantly reduced. In the zebrafish toxicity evaluation, concentrations below 50 ㎍/ml did not show embryotoxicity and showed anti-inflammatory efficacy by reducing NO production due to LPS. The above results are valid to be valuable for use as a functional material that suppresses inflammation by helping the expression of Potentillae Chinensis Herba's respiratory mucus proteins.

Potentillae Chinensis Herba 추출물의 항산화 효능 평가를 위해 DPPH 자유라디칼 소거 활성과 ABTS 양이온 라디칼 활성 평가를 시행하였다. 세포 실험에서 항염증 평가를 위해 호흡기 점막 상피세포 NCI,H292와 RAW264.7 세포 대상으로 항염증 효능을 평가하였다. 그 결과, DPPH 자유라디칼 소거 활성과 ABTS 양이온 라디칼 활성 모두 농도 의존적으로 항산화 활성이 증가하는 것으로 나타났다. 세포 MTT 분석 결과, 각 농도 100 ㎍/ml로 처리한 경우 NCI-H292 세포의 생존율이 70% 미만으로 감소하였고, 이후 실험은 50 ㎍/ml로 진행하였다. 항염증 효능 평가에서는 NO생성, TNF-𝛼, IL-1𝛽, PGE2가 감소하였고, COX-2도 50 ㎍/ml에서 유의하게 감소하였다. Potentillae Chinensis Herba 추출물과 생물전환 추출물의 뮤신 단백질 발현은 MUC5AC 발현이 유의하게 감소하는 것으로 관찰되었다. 이상의 결과는 Potentillae Chinensis Herba의 호흡기 점액 단백질 발현을 도와 염증을 억제하는 기능성 소재로 활용하는데 가치가 있음을 알 수 있다.
