| Abstract: | The method of Ultrasonic extraction was applied to extract the Phospholipid from Chinese traditional medicine Polygonum multiflorum Thunb. The effects of solvent volume, extraction time, power of Ultrasonic extraction on phospholipid extraction were investigated. The content of phospholipid in extracted compounds was determined by ICP - AES. The result indicated that the optimal conditions for 1.5 g Polygonum multiflorum Thunb were 20 mL Folch solvent,time 35min and power 24 kHz. |
