Article Synopsis
- A new technique using ultrasonic-assisted extraction and macroporous resin purification was developed to separate naringin from pomelo peels.
- The extraction efficiency was influenced by factors like the concentration of the extraction agent, the sample-to-solvent ratio, and ultrasonic duration.
- Under optimized conditions, naringin content in pomelo peels reached 2.20%, with a purification rate of 77.26%, and the structure of synthetic naringin dihydrochalcone was confirmed using UV, NMR, and MS spectroscopy.

The performance of adsorption of tea polyphenol and caffine with polyamide resin was investigated. The results obtained by spectrophotometry and HPLC show that the ability of adsorption of tea polyphenol with polyamide is stronger than that of caffine, in which hydrogen bond plays a very important role. The adsorption amount of caffine is 2.
