DOCUMENT TYPE: Journal CA Section: 63 (Pharmaceuticals) Gentiopicroside [20831-76-9], swertiamarin [17388-39-5], sweroside [14215-86-2], amarogentin [21018-84-8] and amaroswerin [21233-18-1] in Gentiana were sepd. and identified by polyamide sheet chromatog. Silica gel TLC was unable to sep. all 5 glucosides. G. manshurica, G. seabra, G. triflora, G. atuntriensis, G. rigescens, G. cephalantha And G. suffristescens contained gentiopicroside, swertiamarin, and sweroside. G. triflora, G. atuntriensis And G. rigenscens contained amarogentin but none of the medicinal plants contained amaroswerin. The content of gentiopicroside in underground parts was higher than that in aerial parts.
