The TPC improved by increasing the solvent’s polarity, independently to extraction method. This is in accordance with the study of Lee et al. (2007) which proves that the recovery of polyphenols from plant materials is influenced by the polarity of the solvent used for the extraction. Contrary to this result Lin et al. (2009) mentioned that acetone extract from lychee flowers presented the highest TPC among three solvents used, methanol, water and acetone. Whereas for leaves of C. siliqua, hexane and ethyl acetate extracts presented the best TPC (Hsouna et al., 2011).
