| Abstract: | Total polyphenol was isolated from Lysimachia christinae Hance by macroporous adsorbent resin. The influence of ethanol concentration, solid/liquid ratio, desorption temperature and times on yields of polyphenol were investigated by orthogonal test. The results showed that the optimal extraction condition was using 60% (V/V) ethanol as desorption solvent at temperature of 50 ℃, solid-liquid ratio for 1:6 (g/ml) and absorption for 120 min. Under this condition, the polyphenol yield reached up to 2.26%. |
