摘要: 黄酮类化合物因具有多种生物活性而成为目前天然产物研究的热点。本研究通过三种检测方法的比较,确定了聚酰胺-UV法为蜂花粉总黄酮的测定方法,其检测波长为360nm,以芦丁为标准品,在0.005~0.025mg/ml范围内,其浓度与吸光度呈良好的线性关系,相关系数R2为0.9998,平均回收率分别为95.53%,稳定性、精密度和重现性均理想,其RSD分别为2.124%(n=3)、0.488%(n=3)、0.875%(n=5)。该法检测油菜蜂花粉中总黄酮含量为1.54%。

Abstract: Flavonoids are widely studied in natural products because of their multifarious bioactivities to human body. The paper compared tree methods of determination and confirmed a method for quantitative determination of total flavonoids in bee- pollen by ployamide-UV spectrophotometry. The standard sample was rutin. The optimum determination wavelength was 360nm. The results showed that a good linear relationship (R2=0.9998) between OD and the concentration of analyte is obtained, within the range of 0.005~0.025mg/ml. The average recovery rate is 95.53%. The stability, precision and repetition are very good, with RSD 2.124%(n=3), 0.488%(n=3), 0.875%(n=5) respectively. The content of the total flavonoids in rape pollen is 1.54% by ployamide-UV spectrophotometry.
