Mango () is a fruit highly consumed for its flavor and nutrient content. The mango peel is rich in compounds with biological functionality, such as antioxidant activity among others. The influence of microwave-assisted extraction variables on total phenol compounds (TPC) and antioxidant activity (TEAC) of natural extracts obtained from mango peel var. Tommy and Sugar were studied using a response surface methodology (RSM) and Artificial Neural Networks (ANN). TPC of mango peel extract var. Tommy was significantly influenced by time extraction (), solvent/plant ratio () and concentration of ethanol () and while mango peel extract var. Sugar was influenced by . TEAC by ABTS was significantly influenced by . Maximum of TPC (121.3 mg GAE / g of extract) and TEAC (1185.9 μmol Trolox/g extract) for mango peel extract var. Tommy were obtained at , and , and for mango peel extract var. Sugar, the maximum content of TPC (224.86 mg GAE/g extract) and TEAC (2117.7 μmol Trolox/g extract) were obtained at , and . The ANN model presented a higher predictive capacity than the RSM These extracts can be used for the development of new products.
芒果（）是一种因其风味和营养成分而被大量食用的水果。芒果皮富含具有生物功能的化合物，如抗氧化活性等。采用响应面法（RSM）和人工神经网络（ANN）研究了微波辅助提取变量对从汤米（Tommy）和砂糖（Sugar）品种芒果皮中获得的天然提取物中总酚化合物（TPC）和抗氧化活性（TEAC）的影响。汤米品种芒果皮提取物的TPC受提取时间（）、溶剂/植物比例（）和乙醇浓度（）的显著影响，而砂糖品种芒果皮提取物受的影响。ABTS法测定的TEAC受的显著影响。汤米品种芒果皮提取物在、和时获得了最大TPC（121.3毫克没食子酸当量/克提取物）和TEAC（1185.9微摩尔 Trolox/克提取物），而砂糖品种芒果皮提取物在、和时获得了最大TPC含量（224.86毫克没食子酸当量/克提取物）和TEAC（2117.7微摩尔 Trolox/克提取物）。ANN模型比RSM具有更高的预测能力。这些提取物可用于开发新产品。
