【摘要】 建立紫外分光光度计测定辣木酒中总黄酮含量的方法。酒样直接与NaNO₂、Al（NO₃）₃、NaOH发生反应,在波长510 nm处测定吸光度值。方法的平均回收率为104.38%,酒样总黄酮含量测定值的相对标准偏差为1.97%,该方法操作简便,稳定性好,可运用于辣木酒总黄酮含量的测定。更多还原

【Abstract】 A method for determining flavonoids content in Moringa oleifera liquor by spectrophotometry had been developed. Wine samples directly reacted with NaNO₂, Al（NO₃）₃ and NaOH, and the absorbance value was measured at wavelength of 510 nm. The average recovery of such method was 104.38 % and RSD was 1.97 %. Such method was simple to operate with good stability, and suitable for the determination of total flavonoids content in Moringa oleifera liquor.更多还原
