| Abstract: | With flaxseeds as raw material, the ultrasound - assistant extraction technology was used to extract lignan.The effects of time, ultrasonic frequency and the ratio of sohd to liquid on the recovery of lignan were investigated. On the basis of single factor trial, the extraction conditions were optimized with Box - Behnken test. Results show the obtained op-timum conditions for the ultrasound - assistant extraction technology are ultrasonic power 300 W, extraction time 21 min,and the ratio of solid to liquid 17. Under the optimum conditions the yield of lignan is 6.54 mg/g. |
