In this paper, the content of phenolic acids in citrus peels of different varieties were analyzed by RP-HPLC. The extraction technique of phenolic acids was studied, and macroporous resin was applied to study primary purification of crude extracts. The main results are listed as follows.
1. The RP-HPLC of 9 phenolic acids was identified. The chromatogram conditions includes HPLC(Shimazu LC-20AT), C18 column (VP-ODS,250x4.6mm,5um), the solution of 4% acetic acid and methanol (volume ratio 80/20...
