Rhoifolin might be a key effect component of total flavonoids. (A) The content of vitexin, rhoifolin, and apiin in the initial state. Calculated amount of vitexin (B), rhoifolin (C), and apiin (D) in plumula nelumbinis with simulated digestion of total flavonoids with salivary solution, gastric solution, and intestinal solution. Cell proliferation analysis in PANC-1 (E) and ASPC-1 cells (F) were treated with 0, 25, 50, 100, and 200 μg/ml total flavone. (G) Cell proliferation analysis in PANC-1 and ASPC-1 cells were processed with 0, 12.5, 25, 50, and 100 μg/ml vitexin, rhoifolin, and apiin.
