淫羊藿总黄酮的超声辅助提取及其抗氧化活性
Ultrasonic-assisted ethanol extraction of flavonoids from Epimedium and their antioxidative effects on fats and oils
摘要
Abstract
Flavonoids were extracted from Epimedium with ultrasonic assistance, using ethanol as extraction solvent. The optimal extracting conditions were obtained based on single factor test and orthogonal experimental design. The hydroxyl radical-scavenging capacities and antioxidative activities against the peroxidation of oils and fats of the flavonoid extracts were obtained compared with reference antioxidants. Results showed that under the conditions of 70% ethanol, 1: 30 (g/mL) material-to-liquid ratio, and 30 min ultrasonic extracting time, the total flavonoid mass fraction of extracts was 2. 246%. The extracts showed good antioxidative effects on oils and fats.关键词
