Effect of an anthocyanidin-zeolite complex (A-Z) was investigated by real-time cell analysis in cultured human epidermoid carcinoma keratinocytes (A431) and human forehead fibroblasts (HFF). A mesoporous zeolite, a potential adsorbent applied in household products, was complexed with an anthocyanidin, extracted from blue flowers ofClitoria ternateaLinn. The A-Z was linearly correlated within a range of 0.05 0.3 mg/ml of the anthocyanidin, analyzed by HPLC, in accordance to Langmuir adsorption isotherm (r= 0.992,p> 0.05). In comparison to zeolite or anthocyanidin alone, A431 and HFF showed significantly cell survival with improved IC50upon exposure to A-Z (p< 0.05). The adsorbed anthocyanidin onto the zeolite reduced the toxic potentials of each.
