Objective: To screen macroporous resins for isolation and purification of total flavonoids of Bidens bipinnata L. (TFB) through investigating the property of adsorption and desorption of 7 kinds of macroporous adsorption resins for TFB.
Methods: The content of total flavonoids was used as the evaluating criteria, and the static and dynamic adsorption-desorption methods were adopted to compare the adsorption quantity, the rate of desorption and adsorption kinetics of different macroporous adsorption resins.
Results: Among 7 kinds of macroporous adsorption resins, the HPD 100 resin was the best for isolating and purifying TFB.
Conclusion: HPD 100 possess a better adsorbability and separating property, and its property is obviously higher than any other resins.

A standardized polyphenol-enriched fraction (IPHRFPPEF) was formulated into a phospholipid complex (IPHRFPPEF-PC) to enhance oral bioavailability and evaluate stability, toxicity, and in vivo anti-inflammatory activity in Sprague Dawley rats. IPHRFPPEF was prepared from crude extract using XAD-HP7/Diaion-HP20 resin column chromatography and analyzed via HPLC and NMR. Total phenolic and flavonoid contents were quantified, with IPHRFPPEF showing higher values than the crude fraction.
