Study on total flavonoids extraction from Mangifera indica L.leaves through the microwave-assisted extraction method

【Objective】The mango leaf flavonoids extraction process was optimized in order to to provide references for the research development of Mangifera indica L. （mango） leaf flavonoid and to broaden the mango leaves comprehensive utilization methods. 【Method】The microwave extraction technology was used for mango flavonoids extraction， and the effects of process conditions on flavonoid concentration were observed and analyzed through the single factor experiment and L9 （34） orthogonal test. 【Result】The factors affecting the total flavonoids extracted from mango leaves through the microwave-assisted extraction method were arranged in the following order: volume fraction of ethanol> microwave power> extraction time> liquid ratio. Under the optimum conditions of 1∶40 liquid ratio， 40% ethanol extraction， and 320 W of microwave power， the total flavonoids were extracted for 2 min. As a result， the total flavonoids mango leaves extraction rate was 4.02%. 【Conclusion】Using the microwave-assisted extraction method to extract the mango total flavonoids has the following advantageous characteristics of being simple， easy， fast， efficient， and economic， which could be effectively utilized as mango leaf resources.
