Mangiferin is a natural xantone extensively distributed in higher plants showing different pharmacological properties. In the present study, an ultrasonic-assisted extraction (UAE) method was evaluated for obtain mangiferin from Mangifera indica L. (c.v Mango Macho) leaves. Differents extraction parameters were optimized using a response surface methodology and the best conditions reached were at 47% ethanol concentration, a liquid-to-solid ratio 47:1, and an extraction time of 63min. under ultrasound irradiation of 150W. In these circumstances, the yield of mangiferin was 24.15±0.015mg/g. For first time, was evaluated the ultrasound assited extraction to higher frecuency and the value of the yield reached was 6.38± 0.062mg/g. Comparison of UAE of mangiferin respect to microwave and aggited tank was realized and the yield obtained by UAE was inferior, however the ultrasonic time was minor respect to conventional extraction technique. The ultrasonic-assisted extraction is an alternative method to use for the extraction of mangiferin from Cuban mangos.
