Optimización del proceso de extracción de mangiferina a partir de piel mango

Abstract

Abstract: The industrialization of mango fruit generates a large quantity peel and seed as by-products. Mango peel is a promising and inexpensive source of mangiferin. In the present study, both the drying of the mango peel and the extraction of mangiferin were optimized. The research was carried out in the laboratories of the Department of Chemistry and Exact Sciences of the UTPL. The response surface methodology was used to optimize both processes. In this sense, temperature and charge/area ratio were selected as depend variables to drying process. Instead, for the ultrasonic assisted extraction the temperature, ethanol-water concentration and time were optimized. For both processes, the mangiferin concentration was the response variable. This xanthone was quantified by HPLC-ESI-IT-MS n. The optimal conditions for the dehydration process were 54 °C and 2.3 kg/m 2, while for the extraction were 51 °C, 50 % ethanol(v/v) and 71 min, reaching a content of 1.50±0.13 mg/g dw. In addition, 38 compounds were identified in the extract obtained under optimal conditions. The results obtained can promote the use of this by-product as a source of mangiferin.
