| Abstract: | Objective To study the purification of total flavonoids from chrysanthemum indicum (CITF) by macroporous absorption resin. Methods CITF was obtained through macroporous absorption resin and UV spectrophotometry was used to analyze the content of total flavonoids. The appropriate conditions including resin type, adsorption and elution properties were confirmed by comparing the quality of CITF. Results The optimized conditions were: macroporous absorption resin AB-8, concentration of original sample 1.2~1.5 g/L, maximum adsorption 16.8 mg/g dry resin, sample adsorbing rate 1 BV/h, sample adsorption times 2, adsorbing time 0.5 h, 50% alcohol as eluent, 4 BV, desorbing rate 4 BV/h, resin repeat adsorption cycles less than 3. Conclusion AB-8 resin can be used to purify CITF. |
