摘　　要：用双波长薄层扫描法测定了不同来源血竭中血竭素的含量 ,λS=475 nm ,λR=6 0 0 nm ,在 0 .2 1～ 1.0 5μg范围内线性良好 ,γ=0 .9992。供试品的同板和异板精密度试验的 RSD值分别为 1.6 8%和 3.47% (n=5 )。结果准确 ,加样回收率为 98.7% ,RSD为 1.13% (n=6 )。To determine the content of Dracorhodin in Xuejie from different places by TLC scanning method,λ S=475 nm,λ R=600 nm. Linear relationship was found in the range of 0.21～1.05 μg(γ=0.999 2). The RSD of precision test about sample in the same plate and the different plate were 1.68% and 3.47% (n=5), respectively. The everage recovery of adding sample was 98.7% (RSD=1.13%, n=6).
