Abstract

Propolis, natural antibacterial agent, which has been used traditional medicine across the globe, is resinous mixture to include abundant bioactive substances. In present study, we investigated antimicrobial activity according to quality characteristics of propolis collected from 9 different regions in Korea. Antimicrobial activity was evaluated by measuring growth inhibition zone using agar well diffusion method against Streptococcus mutans. Constituents analysis of propolis samples were measured through total phenolic contents, total flavonoid contents and quantitative analysis of major compound (pinocembrin) by ultra performance liquid chromatography. As a result, 9 different propolis (10mg/mL) and pinocembrin (1mg/mL) showed antimicrobial activity that has growth inhibition zone more than 11.9mm on S. mutans. The total flavonoid contents of 8 different propolis excluding Jeju island were in compliance with standard of health functional food in Korea and were found to affect antimicrobial activity on S. mutans when contained over 10mg/g. In addition, when content of pinocembrin in propolis was ranged from 12mg/g to 32mg/g, each propolis excluding Jeju island exhibited antimicrobial activity alike. These results indicate that pinocembrin plays a important role for antimicrobial activity of propolis collected from 8 different regions in Korea, and that it can be used as basic data for standardization of Korean propolis.

충치발생의 주요 원인균으로 알려진 S. mutans를 이용하여 건강기능식품으로 사용되는 프로폴리스를 9개 지역으로부터 수집한 후 생리활성 물질 탐색과 주요성분 함량에 따라 활성차이를 조사하였다. S. mutans에 대한 항균활성은 제주도, 경상북도, 경상남도, 충청북도, 충청남도, 전라북도, 전라남도, 경기도, 강원도 프로폴리스 및 pinocembrin에서 모두 관찰되었다. 제주도를 제외한 모든 프로폴리스에서 총 플라보노이드 함량이 10mg/g 이상으로 건강기능식품 기준 및 규격에 적합하였고, 19mg/g 이상일 경우 우수한 항균활성을 유사하게 나타내었다. 국산 프로폴리스의 주요성분으로 알려진 pinocembrin의 UPLC 정량분석에서는 제주도산 프로폴리스를 제외한 모든 시료에서 주성분으로 검출되었고 12mg/g 이상일 경우 항균활성에 큰 영향을 주는 것으로 확인되었다.
