用双波长薄层扫描法测定乌鸡白凤冲剂中人参皂甙Ｒｅ的含量，以氯仿－甲醇－水（６５∶３５∶１０）１０℃以下放置的下层溶液为展开剂，在波长λＳ＝５２５ｎｍ，λＲ＝６８０ｎｍ处进行扫描，加样回收率为９７．５％，ＲＳＤ＝２．３７％。
The content of ginsenoside Re in Wuji Baifeng Granules was determined by dual-wavelength thin layer scanning method. The lower layer solution of chloroform-methanol-water (65:35:10) placed below 10°C was used as developing solvent at wavelength λS=525nm, λR. Scanning was performed at 680 nm. The recovery rate was 97.5% and the RSD was 2.37%.
