Epimedium bioactive substances from the research and anti-oxidation
Abstract: Epimedium optimization of icariin in the extraction process. Method: icariin in indicators for the detection, according to extracts of time, the number of extraction, temperature, alcohol concentration four factors used L9 (34) Orthogonal test. Ultraviolet spectrometer of icariin content. Results: The impact of extraction from the number of factors, from temperature, liquid ratio, alcohol concentration. Conclusion: The concentration of 40 percent ethanol, feed than 180 ml, temperature of 90 ℃, from the number four best effect. Antioxidant results:0.6 ml at the maximum 83 per cent clearance rate. In 6.5 ml, 0.8A maximum absorbance.
