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 +/- 0.4 mg/ml, respectively. Standardised ethanolic extracts of the R indica leaf had a solid content of 9.1 +/- 0.7%, mangiferin concentration of 73 +/- 0.17 mg/g of dry weight of the extract, free radical scavenging activity (IC50) of 0.1 7 +/- 0.02 mg/ml and total phenolic content of 590 +/- 48 mg/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. (c) 2008 Elsevier Ltd. All rights reserved.
