Comparative Study on Content of Proanthocyanidins from Lycium Ruthenicum, Chinese Wolfberry and Black Currant
Objective To compare the contents of proanthocyanidins from Lycium ruthenicum, Chinese wolfberry and black currant. Methods The content of proanthocyanidins was determined by spectorphotometry with vanillin-HCl as the color-developing agent. Results In the measured samples, the average contents of proanthocyanidins were 5.04 %, 0.48 % and 0.58 %, respectively, in Lycium ruthenicum, Chinese wolfberry and black currant. Conclusion The content of proanthocyanidins can be relatively high in Lycium ruthenicum, so Lycium ruthenicum can be an ideal plant resource for the extraction of proanthocyanidins.
