摘要
建立了以滤纸为基质的中草药有效成分芦丁、丹皮酚的固体表面延迟荧光分析法(roomtemperaturedelayedfluorimetry,RTDF)。对影响延迟荧光强度的各种因素进行了详细的研究,实验表明,芦丁的线性范围为5×10^(-6)~1×10^(-4)mol/L,检出限为0.52ng/斑,丹皮酚的线性范围为1×10^(-6)~1×10^(-3)mol/L,检出限为0.08ng/斑。
The solid surface room temperature delayed fluorimetry (RTDF) of rutinum and paeonol, effective compoents in Chinese herbal medicine was established with filter paper as a solid substrate. Meanwile, various factors influencing RTDF intensity were studied in detail. Experiments showed that the linear range of analytical curve was 5 × 10^(-6) ~ 1 × 10^(-4)mol/L for rutinum and 1 × 10^(-6) ~ 1 × 10^(-3)mol/L for paeonol. The detection limit was 0. 52 ng/spot for rutinum and 0. 08 ng/spot for paeonol.
