用大孔树脂吸附法分离过路黄中的总多酚,通过正交试验考察乙醇体积分数、同液比、吸附温度和吸附时间对总多酚提取率的影响.结果表明:用60%(V/V)乙醇作为解吸剂,在固液比为1:6(g/ml),50℃条件下吸附120min,总多盼提取率为2.26%.
用大孔樹脂吸附法分離過路黃中的總多酚,通過正交試驗攷察乙醇體積分數、同液比、吸附溫度和吸附時間對總多酚提取率的影響.結果錶明:用60%(V/V)乙醇作為解吸劑,在固液比為1:6(g/ml),50℃條件下吸附120min,總多盼提取率為2.26%.

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%.
