摘要(Abstract):

用薄层扫描法测定了知母药材及含知母中成药中菝葜皂甙元的含量。苯-丙酮(9:1)为溶剂,香草醛-硫酸显色,测定波长445nm,参比波长600nm。
The sarsasapogenin content in Anemarrhena asphodeloides and its preparations was assayed by TLC-densitometric method. The developing solvent used was benzene-acetone (9: 1). The chromatographic plate was sprayed with a mixture of 8% vanillin in alcoholic solution-70% H_2SO_4 solutoin(0.5: 5). This plate was scanned using 445nm as wavelength λ_s and 600nm as wavelength λ_R.
