以芦丁为标准品,对NaNO2-Al(NO3)3-NaOH法和AlCl3法测定新疆昆仑雪菊总黄酮含量的结果作了比较。结果表明:NaNO2-Al(NO3)3-NaOH法的测定结果比AlCl3法对于高原雪菊和平原雪菊分别约高19.76 mg/mL和9.34 mg/mL, AlCl3法适宜酸度为pH>5.5。邻苯二酚干扰实验表明,平均误差为0.019 mg/L,随着邻苯二酚量的增加,测得值无上升趋势。AlCl3法的线性方程为:A=0.000638+0.8623C,r2=0.9992。因此,对含酚类、酸类较多的昆仑雪菊应采用三氯化铝法测定其总黄酮的含量。

With rut in as the standard substance, comparing the NaNO2-Al (NO3)3-NaOH determination of total flavonoids content in Xinjiang Kunlun snow chrysanthemum method and AlCl 3 method. The results showed that:NaNO2-Al(NO3)3-NaOH assay results than the AlCl3 method for the Plateau snow chrysanthemum and plain snow chrysanthemum was approximately 19.76 mg/mL and 9.34 mg/mL, AlCl3 acidity was pH>5.5. The experiment showed that the catechol interference, the average error was 0.019 mg/L, with the increase of the measured value of catechol, no upward trend. Linear equation AlCl3 method was A=0.000 638+0.862 3C,r2=0.999 2. Therefore, determination of the total flavonoids of phenols, acids more Kunlun snow chrysanthemum should be adopted AlCl3 method.
