Jinhua Ham

This study was designed to evaluate the antioxidant activity of samples extracted from Jinhua ham by using such chemical assays as DPPH, scavenging hydroxyl free radical and ABTS. The results demonstrate that antioxidant capacity of the extracted sample is lower than oxidation capacity of Vc. The IC50 spot of samples ranges between 0.6 % and 2.5 % (mass fraction of solute).

Synthetic Routes

Two synthetic routes to prepare a water-soluble stable free radical were investigated. The first product, sodium-2,4-dinitro-5-(4′-amino-2′,2′,6′,6′-tetramethylpiperidine-1-oxyl)benzene sulfonate, was water soluble but the sulfonate group was not readily replaceable with nucleophiles. The second synthetic route yielded N(4′-(2′,2′,6′,6′-tetramethylpiperidine-1-oxyl))-3,5-dinitro-4-sodium sulfonate benzamide, which was water soluble and its sulfonate group was readily replaced by nucleophiles.
