Abstract:
The optimum technology of simultaneously extracting polygonin and resveratrol from polygonum cuspidatum is studied. Orthogonal design method is used to optimize the extraction and separation conditions,and HPLC method is used to determine their contents. The ethanol as extraction solvent,ultrasonic assisted extraction,the optimum condition is 80% ethanol,and solid-liquid ratio of 1:20,extraction temperature of 60 ℃,extracting time for 40 min,giant knotweed glycosides and the extraction of resveratrol content of 2.42% and 0.41% respectively. A conclusion is conducted that the selected process is good in stability, and simple in operation.
