Moringa oleifera is the most widely cultivated species of the genus Moringa, which is the only genus in the family Moringaceae. The tree is grown mainly in semi-arid, tropical, and subtropical areas. Moringa leaves have been used as a herbal remedy from India. It has an impressive range of medicinal uses with high nutritional value. Moringa leaf is rich in protein, vitamins and minerals （Met, Cis, Trp, Lys, V.A., beta-carotene, V.C., Ca, Fe, K and etc.） In this study, we measured the superoxide dismutase （SOD） activity and total polyphenol content of Moringa leaf tea. The SOD assay kit WST-1 （Dojindo Molecular Technologies, Inc） was used for the measurement of SOD activity in vitro for the moringa tea sample. It measured it by using the microplate reader （BIO-RAD Model 550） by 450 nm. The total phenolic content of extracts was determined using to the Folin-Denis Method by 700 nm. As results, Moringa tea extract solution had the SOD activation of 64.5％, the content of a total polyphenol of the Moringa tea was 9.57 mg/100 ml. The content of the total polyphenol of Moringa leaf was 4.107 g/100 g （240μmol/g） in gallic acid equivalents. |
