This paper elucidates the correlation between the yield of mangiferin extraction from Phaleria macrocarpa fruits to the total phenolic content (TPC), total flavonoid content (TFC) and antioxidant activity (AA). Mangiferin extraction was performed using an ultrasonic assisted extraction (UAE) method. The effect of particle size, solvent to solid ratio, solvent type, ethanol concentration, sonication amplitude and extraction time were studied. The best UAE condition was found using a particle size of 125–250 μm, solvent to solid ratio of 40 mL/g, 40% ethanol, sonication amplitude of 60% and extraction time of 5 min, which produced 28.6 mg mangiferin/g DW, 78.7 mg GA/g DW, 263.2 mg QE/g DW and 57.2% DPPH-RSA. The regression analysis showed a significant (p < 0.05) correlation between the mangiferin yield and either TPC, TFC or AA. The finding reported in this work provides a useful method to predict the mangiferin yield based on TPC, TFC or AA, without needing the actual external standard.

本文阐明了从Phaleria macrocarpa中提取芒果苷的产量之间的相关性果实中的总酚含量（TPC），总黄酮含量（TFC）和抗氧化活性（AA）。芒果苷的提取使用超声辅助提取（UAE）方法进行。研究了粒径，溶剂与固体比，溶剂类型，乙醇浓度，超声处理幅度和萃取时间的影响。发现最佳的阿拉伯联合酋长国条件是粒径为125–250μm，溶剂与固体的比率为40 mL / g，乙醇为40％，超声处理振幅为60％，萃取时间为5分钟，产生28.6 mg芒果苷/ g DW ，78.7 mg GA / g DW，263.2 mg QE / g DW和57.2％DPPH-RSA。回归分析表明，芒果苷产量与TPC，TFC或AA之间存在显着（p <0.05）相关性。这项工作报告的发现为基于TPC，TFC或AA预测芒果苷产量提供了一种有用的方法，
