Their structures were confirmed by 1H NMR, 13C NMR, 2D NMR, and MS spectral analysis, and they have been elucidated as published or publishing papers [12], [13]. Quercetin 7-O-β-d-glucoside (4), kaempferol-3-O-β-d-glucoside (7), phloretin (11), quercetin (30) and kaempferol (31) were bought from Weikeqi Standards Corporation (Chengdu, China). 3-hydroxy phloretin (8) was prepared by acid hydrolysis of 2. Phloretin-2-O-β-d-glucuronide (20) and phloretin-4′-O-β-d-glucuronide (24) | ||
