Abstract:

In the present study, we described a novel, simple, and scalable method for isolating and purifying natural mangiferin from fresh mango leaves. An ultrasonic-assisted method was used to extract mangiferin from mango leaves using methanol as the solvent. The yields of the mangiferin crude extract and purified mangiferin recrystallized from a mixture of methanol and trichloromethane (10:1, v/v) were 1.41% (purity 86.5%) and 0.75% (purity > 99.6%), respectively. The purity of mangiferin was assessed by UV spectroscopy and HPLC. The structure of the purified compound was confirmed spectroscopically by UV, IR, Q-TOF/MS, 1H NMR, and 13C NMR. The method described herein to isolate mangiferin was simple, inexpensive, rapid, and efficient. Moreover, we, for the first time, obtained mangiferin with a purity of more than 99.6% using this method.
