| Abstract: | The extraction conditions of polyphenol from the husk of earthnut by Ultrasound process were studied. Influences of extraction power, and extraction time on the content of polyphenol were investigated, and suitable conditions were deter- mined based on the single factor tests. They were as follows: extraction power 300 kW, extraction time 17.5 min, 60% ethanol was used as a modifier, and its dosage was 17.5 ml for per gram material and the yield is 6.45%. |
