| Abstract: | Extraction condition of proanthocyanidins from the purple sweet potatos was investigated by examining the effects of extraction times,solvent concentration,temperature,time,solid-liquid ratio and pH on the proanthocyanidins yield using single factor method coupled with orthogonal array design.Results showed that ultrasound-assisted extraction's yield is the best,hot reflux extraction's yield is middle,soxlet extraction's yield is the lowest.The best extraction conditions for ultrasound-assisted extraction i... |
