Novel Mechanisms of Green Tea Anti-Oxidants by Mu-SR, INS and DFT Experiments

DOI

A proposal is made to continue ongoing ALC-muSR experiments on the green-tea anti-oxidant EGCG and its analogue. Several overlapping resonances observed on HiFi made it difficult to abstract precise hyperfine coupling constants (hfccs), hence high transverse field muon spin rotation (TF-muSR) measurements were carried out at PSI hinting at additional radicals being formed, whose resonance fields, determined by the hfccs, lie outside the region studied at ISIS. Results were near-identical to the HiFi ones in the matching ranges (~1.4-2.2 T), adding confidence that H-addition is indeed pronounced in EGCG. Experiments on the solvated samples failed to produce good resolution due to time-limitations imposed by relatively low solubilities of EGCG and its analogue. However, solvated spectra is required to make these results biologically-relevant and publishable in a high-impact journal.
