抄録

Two new methods for the determination of gentiopicroside in gentian radix and Gentiana scabra radix were developed by the combination of thin-layer chromatography (TLC) and spectrophotometry. In the preparative TLC-ultraviolet (UV) method, gentiopicroside contained in the methanol extract ofsamples is quantitatively separated by preparative TLC (detection by a PAN UV lamp) and the amount is determined from the absorbance at 270 nm by using a calibration graph. In the TLC-densitometer (DM) method, the methanol extract containing gentiopicroside is developed on the TLC plate, and the amount of gentiopicroside (Rf=ca. 0.4) is measured by TLC densitometry using a dual-wavelength TLC scanner. By these two methods, the content of gentiopicroside vras determined as 1-2% in gentian idix (Osaka market product), 1-3% in Gentiana scabra radix (Osaka market product), and 7-10% in the fresh root of Gentiana scabra BUNGE.
