摘要

对芒果(Mangifera indica)和野生芒果(Irvingia gabonensis和Irvingia wombolu)脱脂仁粉的体外抗氧化活性和细胞毒性进行了分析。3种核型的干物质含量在93% ~ 95%之间。在脱脂方面，欧文尼亚品种的百分比出油率与芒果相似，高出200%。采用2,2 -二苯基-1-苦酰基肼(DPPH)法测定2个Irvingia品种(DIGK和DIWK)的抗氧化活性，其IC50值相近(p>0.05)，但显著高于Mangifera indica kernel (DMIK) (p<0.05)。同样，铁还原抗氧化能力(FRAP)技术和细胞毒性试验的结果证实了DMIK对Irvingia籽粒的更高效力。

Comparative Study on Antioxidant Activity and Cytotoxicity of Defatted Kernels of Mango (Mangifera indica) and Wild Mango (Irvingia gabonensis and Irvingia wombolu)

Defatted kernel powder of mango (Mangifera indica) and wild mango (Irvingia gabonensis and Irvingia wombolu) were analysed for their in-vitro antioxidant activity and cytotoxicity. Dry matter content of the three kernel types were in the range of 93 to 95%. On defatting, the percentage oil yield of the Irvingia varieties were similar and 200% higher than that of Mangifera indica. The antioxidant activity using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) technique showed that the two Irvingia varieties (DIGK and DIWK) had similar IC50 (p>0.05) but significantly higher than that of Mangifera indica kernel (DMIK) (p<0.05). Likewise, results from the Ferric Reducing Antioxidant Power (FRAP) technique and Cytotoxicity assay confirmed the higher potency of DMIK over the Irvingia kernels.
