Isolation and purification of effective components in Plumula Nelumbinis by macroporous adsorption resins / 中草药

Objective To investigate the adsorption function of macroporous adsorption resins for the separation and purification of the effective components in Plumula Nelumbinis. Methods AKS-W, AB-8, and H214 resins were systematically studied for their adsorption capability, and the contents of the liensinine, isoliensinine, and neferine were determined by HPLC. Results AKS-W Resin had a preferable adsorptive and separateive effect for the effective components in Plumula Nelumbinis. The products containing 10.2% liensinine, 6.7% isoliensinine, and 11.9% neferine could be obtained. Conclusion Macro-porous-type and non-polar adsorption resin AKS-W is an ideal adsorbent for the extraction of the effective components in Plumula Nelumbinis.
