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.
