摘要:

为了测定青海产18种菊科植物中总黄酮含量及建立其检测方法,我们采用三氯化铝比色法,以芦丁为对照品,在检测波长为421 nm条件下测定青海产18种菊科植物中总黄酮含量。结果表明,18种菊科植物中总黄酮含量在线性回归方程为y=0.022 6x+ 0.010 5,总黄酮在2~30 μg/mL范围内,浓度与吸光度呈良好的线性关系(R2=0.998)。青海产18种菊科植物的总黄酮含量范围在0.41~18.67 mg/g之间,其中香青属中两种植物总黄酮含量最高,平均含量达到15.72 mg/g。本研究精密度、稳定性和重复性良好。该方法操作简单且准确实用,本研究为更深入地研究菊科植物、开发其应用价值奠定理论基础。

Abstract:

To establish a method for the determination of total flavonoids in 18 species of Compositae from Qinghai Province,we used AlCl3 colorimetry to determine the content of total flavonoids at 421 nm by UV spectrophotometry with rutin as control.The results showed that the linear regression equation y=0.022 6x+ 0.010 5 and R2=0.998 and the rutin concentration had a good linear relationship with absorbance in the range of 2-30 μg/mL.The precision,stability and repeatability were good.The content of total flavonoids in 18 species of Compositae in Qinghai ranged from 0.41 to 18.67 mg/g,the content of total flavonoids in two species of Anaphalis is the highest with an average of 15.72 mg/g.The method is simple,accurate and practical,which lays a theoretical foundation for further study and development of Compositae plants.
