Abstract
|
|
|
|
Antioxidant activity of gingerol, a component of ginger, was studied in β-carotene-linoleic acid-water emulsion system. Crude gingerol extracted from ginger was separated and purified by thin-layer chromatography (TLC) into two bands. The two bands were identified as 6- and 10-gingerol by color reactions on TLC plate, acid dehydration reaction, infrared and nuclear magnetic resonance spectrometry. The antioxidant activity of gingerols (mixture of 6- and 10-gingerol) separated from ginger was remarkable, but lower than that of BHA or BHT.
