“…현재 사용하고 있는 합성 항산화제는 독성에 대한 문제가 제기되고 있다 [8,9]. 따라서 활성산소를 보다 안전하 게 소거하기 위하여 그에 따른 대안으로 천연 항산화 물질에 대한 관심이 높아지고 있으며, 천연 물질이나 식품을 이용한 소재 개발에 대한 연구가 활발하게 이 루어지고 있다 [10,11]. 본 연구에서는 탁월한 항산화 기 능 식물로 알려진 녹차, 어성초, 자소엽을 사용하여 항 산화 기능이 우수한 복합물질을 개발하고자 연구를 진행하였다.…”

In the present study, antioxidant activities and tyrosinase inhibition of Perilla frutescens, Houttuynia cordata and Camellia sinensis extracts and the extract mixtures (PHC) were investigated. PHC showed 80.2% and 98.0% of free radical scavenging activity in DPPH and ABTS analysis, respectively, and 50% tyrosinase inhibition in 1000 µg/mL concentration. HaCaT cells did not show cell toxicity in 100 µg/mL of the PHC. Furthermore, HaCaT cell viability by co-culture with extract H. cordata was increased more than 10% compared with untreated cells. However, the cell viability was decreased in 500 µg/mL of the extract C. sinensis and the PHC. These results suggested that about 100 µg/mL concentration of the PHC showed proper tyrosinase inhibitory effect and antioxidant activities. The PHC could be used as multifunctional cosmeceutical agents.
