Assessment of the Bioaccessibility of Trace Elements in Cat’s Claw Teas by In Vitro Simulated Gastrointestinal Digestion Using FAAS

The aim of this study was to evaluate the bioaccessibility of Ca, Fe, Mg, Mn, and Zn in cat’s claw plant teas through in vitro gastrointestinal digestion with gastric and intestinal juice solutions. The total concentrations and bioaccessible fractions of Ca, Fe, Mg, Mn, and Zn were measured by flame...

Description
Summary:The aim of this study was to evaluate the bioaccessibility of Ca, Fe, Mg, Mn, and Zn in cat’s claw plant teas through in vitro gastrointestinal digestion with gastric and intestinal juice solutions. The total concentrations and bioaccessible fractions of Ca, Fe, Mg, Mn, and Zn were measured by flame atomic absorption spectrometry (FAAS). The results obtained showed that Zn was the most bioaccessible element in the teas, contributing a mean of 57.9% by infusion and 62.5% by decoction. Among macroelements, the Ca was less bioaccessible with 17.4% recovery. The bioavailability assessment revealed that daily intake of 200 ml of cat’s claw teas cover about 1.0% of manganese RDA.
