Gentiana (gentian) root is mutagenic in bacteria, which is due to the xanthone derivatives, gentisin and isogentisin. In experimental animals Gentiana olivieri is... 

The following substances can lead to lowered cholesterol levels if they are present in high concentrations L-cysteine, gentisinic acid, aminoantipyrin, homogentisinic acid and glutathione. 

The following substances can lead to reduced triglyceride values if present in high concentrations gentisinic acid, nitrofurantoin, oxipurinol and oxytetra-cycline. 

Samples containing metamizol, EDTA, gentisinic acid or to which lipid reducers have been added (Liposol), cannot be measured by the Seralyzer. These substances interfere with the measurement. 

There have been reports in the literature (S18, S120) to the effect that le-vodopa, isoniazid and gentisinic acid are claimed to produce a marked drop in glucose concentration. These data, however, have not been quantified in detail. Contamination with isopropyl alcohol results in lower recovery (S195). 

Main components The bitter principles, gentiopicrin (up to 3%) and amarogentin (in G. lutea amaropanin and amaroswerin in the other species), which is only present in small amounts, but possesses a far stronger bitter taste, as well as xanthone derivatives (gentisin and others), tannins, mucilage, considerable amounts of fermentable sugar... 

Besides gentiopicroside Gentianae radix (1) shows two prominent quenching xanthone zones with gentisin/isogentisin at the solvent, front and the gentioside at R, — 0.3.
