Mineral Content and Antioxidants Activity of Portulaca oleracea

국문 초록 (Abstract)

쇠비름의 생리활성을 알아보기 위하여 무기물 함량 및 항산화 활성을 분석하였다. 쇠비름의 무기물은 총 9종 검출되었으며, 총량은 6025.80 mg/100 g으로 칼륨이 3846.99 mg/100 g으로 가장 높았다. 물 및 에탄올 추출물의 추출 수율은 각각 14.84% 및 24.93%였다. 쇠비름 에탄올 추출물의 총 페놀화합물 및 플라보노이드 함량은 각각 58.16 mg/g, 20.08 mg/g으로 물 추출물(49.09 mg/g, 14.98 mg/g)보다 유의적으로 높았다. 항산화 활성 및 아질산염 소거활성은 시료의 첨가량에 따라 유의적으로 상승하였으며, 에탄올 추출물이 물 추출물보다 활성이 더 높았다. α-glucosidase 저해활성은 에탄올 추출물이 유의적으로 높은 활성을 보였다. 따라서, 쇠비름의 물 및 에탄올 추출물은 항산화 활성 및 혈당강하에 효과적일 것으로 판단되며, 시료 중의 무기물, 페놀 화합물 및 플라보노이드 함량과 관련성이 높을 것으로 사료된다.

We investigated the mineral content and antioxidant activity of Portulaca oleracea for biological properties. Total mineral content was 6025.80 mg/100 g, and potassium was the highest at 3846.99 mg/100 g. Water and 80% ethanol extract yields were 14.84% and 24.93%, respectively. The contents of phenolic compounds and flavonoids of ethanol extract were 58.16 mg/g and 20.08 mg/g, and were significantly higher than that of its water extract (49.09 mg/g and 14.98 mg/g, respecitvely). Antioxidant activities and nitrite scavenging activity was significantly elevated in a dose-dependent manner, and that of ethanol extract was higher than that of the water extract. α-Glucosidase inhibition activity of ethanol extract was significantly higher than the water extract as well. We suggest that the biological properties of Portulaca oleracea are due to its mineral and phenolic contents.
