Abstract

This study evaluated antimicrobial efficacy and antioxidant effect of fraction isolated from Coptis Radix and confirmed its possibility as a cosmetic material. The extracts of isolated from Coptis Radix conducted an antimicrobial activity against Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, Candida albicans by disc diffusion method and measure clear zone. As a result, it was confirmed that antimicrobial activity against S. aureus and candida. A was observed in all samples except Fr 1. The activity of 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging and The activity of 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) cation radical scavenging were determined by antioxidant assay according to the concentrations (50, 125, 250) ${\mu}g/mL$ of extracts of isolated from Coptis Radix. As a result, DPPH radical scavenging activity of Fr 1, 2, 3, 4 at $250{\mu}g/mL$ was 11.4%, 30.3%, 42.0% and 53.1%, respectively and $ABTS^+$ radical scavenging activity was 28.6%, 96.2%, 98.6% and 97.1% at the same concentration, respectively. Fr. 3 and 4 showed higher radical scavenging activity than the positive the control group BHT at the same concentration. In the WST assay results of measuring the cytotoxicity of Coptis Radix, except for Fr. 4, Fr. 1, 2 and 3 did not show toxicity. As a result, the fractions isolated from Coptis Radix can be regarded as a cosmetic material having antimicrobial activity and antioxidant ability.

본 연구는 황련으로부터 분리된 fraction의 항균효능과 항산화 효과를 평가하고 그것의 화장품 소재로서의 가능성을 확인하였다. 황련으로부터 분리된 fraction의 항균활성은 Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, Candida albicans 균주로 disc diffusion 방법을 통해 생육저해환(clear zone)을 측정하였다. 그 결과 Fr. 1을 제외한 모든 시료에서 S. aureus와 candida. A에서 항균활성을 나타내는 것으로 확인 하였다. 항산화 평가를 위해 황련 fraction의 농도(50, 125, 250) ${\mu}g/mL$에 따라 처리하여 1,1-diphenyl-2-picrylhydrazyl (DPPH) 라디칼 소거능과 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) 양이온 라디칼 소거능을 확인하였다. 그 결과 Fr. 1, 2, 3, 4의 $250{\mu}g/mL$ 농도에서 DPPH 라디칼 소거능 활성이 각 11.4%, 30.3%, 42.0%, 53.1%로 $ABTS^+$ 라디칼 소거능 활성은 동일농도에서 각 28.6%, 96.2%, 98.6%, 97.1%로 나타났다. Fr. 3, 4는 동일농도의 대조군 BHT 활성의 86.5%보다 높은 활성산소 저해능을 보였다. 황련의 세포독성을 측정한 WST assay 결과에서 Fr. 4를 제외하고는 Fr. 1, 2, 3은 독성을 나타내지 않았다. 이러한 결과로 황련으로부터 분리된 fraction은 항균능과 항산화 능을 가지는 화장품 소재로서의 가치를 가진다고 볼 수 있다.
