Anti-corrosive properties of xanthone on mild steel corrosion in sulphuric acid: Experimental and theoretical investigations[Reference: WebLink]

METHODS AND RESULTS:
The anti-corrosive effect of xanthone (XAN) on the corrosion of mild steel in 0.5 M H2SO4 has been studied by gravimetric and UV–visible spectrophotometric methods at 303–333 K. Results obtained revealed that XAN performed excellently as a corrosion inhibitor for mild steel in sulphuric acid solution. Inhibition efficiency increases with increase in concentration of XAN but decreases with rise in temperature which is suggestive of physical adsorption mechanism although chemisorption may also play a part. Dubinin–Radushkevich adsorption isotherm model was found to adequately describe the adsorption of XAN onto the mild steel surface. Kinetic parameters of activation and thermodynamic parameters using the statistical model were calculated and discussed.
CONCLUSIONS:
The corrosion process in 0.5 M H2SO4 in the absence and presence of XAN follows first-order kinetics. The UV–visible absorption spectra of the solution containing the inhibitor after the immersion of mild steel specimen indicate the formation of a XAN–Fe complex. Quantum chemical calculations have been performed using DFT and several quantum chemical indices were calculated and correlated with the inhibitive effect.

Bioavailability and antioxidant effects of a xanthone-rich Mangosteen (Garcinia mangostana) product in humans.[Pubmed: 19807152 ]

Oxidative damage is involved in many chronic diseases including those cited as the major causes of death in Western societies such as cardiovascular disorders and cancer. Antioxidants may prevent these degenerative processes by various mechanisms including the scavenging of free radicals. Intake of antioxidant supplements is associated with preventing oxidative damages.
METHODS AND RESULTS:
This study investigated the absorption and antioxidant effects of a xanthone-rich mangosteen liquid in healthy human volunteers after the acute consumption of 59 mL of the supplement. The liquid contained mangosteen, aloe vera, green tea, and multivitamins. Results indicated that alpha-mangostin and vitamins B(2) and B(5) were bioavailable, with observed C(max) at t(max) of around 1 h. The antioxidant capacity measured with the oxygen radical absorbance capacity (ORAC) assay was increased with a maximum effect of 18% after 2 h, and the increased antioxidant level lasted at least 4 h.
CONCLUSIONS:
Overall, this study demonstrated the bioavailability of antioxidants from a xanthone-rich mangosteen product and its in vivo antioxidant effects.
