|Abstract||Profiles of selected phenolic constituents of 2 apple cultivars, Northern Spy and Ida Red, commonly used for processed products Were compared. Although chlorogenic acid was the principal phenolic in both cultivars, there were significant quantitative differences. A new solid-phase extraction (SPE) and high-performance liquid chromatographic (HPLC) separation using polymeric resins was developed for this experiment. Quantification was by ultra-violet (UV) absorbance using a diode array detector. The performance of this new method was compared with that of a published liquid-liquid extraction (LLE) method, based on linearity of detector response, limits of detection, reproducibility of analysis, and recoveries from spiked apple samples.|
