Standardised Mangifera Indica Extract is an Ideal Antioxidant
Food chemistry(2009)
摘要
The standardised ethanolic and aqueous extracts of Mangifera indica leaf were prepared and analysed for their free radicals scavenging activity. The IC50 values using the DPPH assay were 0.17±0.02 and 0.49±0.4mg/ml, respectively. Standardised ethanolic extracts of the M. indica leaf had a solid content of 9.1±0.7%, mangiferin concentration of 73±0.17mg/g of dry weight of the extract, free radical scavenging activity (IC50) of 0.17±0.02mg/ml and total phenolic content of 590±48mg/g of extract. The protection exhibited by these extracts against lipid peroxidation was superior to butylated hydroxytoluene (BHT) and commercial grape seed extract. These extracts at higher concentration did not exhibit pro-oxidant activities when compared to vitamin C. Our findings also show that the aqueous and ethanolic extracts of M. indica leaf protect NIH/3T3 cells from oxidant-induced cell death.
