국내 자생 꽃 품종에 따른 항산화활성 비교
2013
Nine kinds of flowers were selected by its antioxidative activities evaluated. DPPH(1,1-diphenyl-2-picryl hydrazil), reducing power, total phenol contents, total flavonoid contents, and antimicrobial activity inhibitory effects of nine natural flower varieties were examined using ethanol extract (80%, v/v). DPPH radical scavenging of Agastache rugosa (fisch.&Mey.) kuntze (IC 50 = 74.6 μg/mL) and solidago virga-aurea var. asiatica (IC 50 = 99.6 μg/mL) showed higher antioxidant activity compared with those of the other varieties. Reducing power of Agastache rugosa (fisch.&Mey.) kuntze (OD700 = 1.0) had higher antioxidant activity. Agastache rugosa (fisch.&Mey.) kuntze showed the highest content of total phenol (134.6 mg GAE/g). However, total flavonoid (554.6 mg QE/g) exhibited the lowest. These results suggest that nine kinds of flower with 80% ethanol extracts have significant antioxidant activity.
