땅빈대 추출물의 항산화 활성 및 세포독성 효과

초록

The antioxidant activities, anti-inflammatory activity and cytotoxic effects of methanol extract from Euphorbia humifusa were evaluated in this study. Total phenolic compound contents were 68.35±0.16 mg/g and total flavonoid compound contents were estimated as 38.74±1.26 mg/g. EC50 values for DPPH radical scavenging activity of methanol extract was 56.26±0.66 μg/mL and those of positive controls as ascorbic acid, α-tocopherol and BHA were 8.38±0.14 μg/mL, 16.45±0.89 μg/mL and 21.18±1.01 μg/mL respectively. NO scavenging activity increased in depending on concentration of extract. Treatment of RAW 264.7 cells with extract caused inhibition of LPS-induced nitric oxide production. The cell viability showed that the methanol extract had cytotoxicity in the growth of breast cancer cell (66.54±1.91% at 400 μg/mL conc., 43.98±3.35% at 800 μg/mL conc.). Based on the results, It was suggested that the methanol extract of Euphorbia humifusa has a potential candidate for functional cosmetic and medicine.
