Study on ultrasonic extraction of total flavone from seeds of Chinese dates with orthogonal test
摘要
Abstract
The optimal condition for ultrasonic extraction of flavone from seeds of Chinese dates was investigated by orthogonal test.The total flavone content of seeds of Chinese dates was determined by using spectrophotometry method with rutin as reference substance.In the single factor analysis,the effect of ultrasonic-wave power,extraction time,extraction temperature,solid-liquid ratio and ethanol（extraction solvent）volume fraction were measured.The orthogonal test was used to optimize the conditions of extraction.The results showed that the order of extraction effectiveness was as follows：extraction temperaturesolid-liquid ratioextraction timeethanol volume fractionultrasonic-wave power.The optimum conditions were extraction temperature 55℃,solid-liquid ratio1：50,extraction time 40min,ethanol volume fraction 50%,and ultrasonic-wave power 400W.Under the optimized extraction conditions,the yield of flavone crude product was 12.45%,the content of total flavone was 6.83mg·g-1.The results indicated that operating efficiency of extracting total flavone from seeds of Chinese dates was remarkably increased by orthogonal test and ultrasonic wave extraction.关键词
