Active constituents of Gentian.Radix Gentianae.Gentian root.:

Major Effective content:gentiopicrin, C16H20O9, (1.37%~6.34%).

 Synonyms of Gentiopicrin:Gentiopicrin,Gentiopicroside.

 Gentian contains bitter substances such as the glycosides gentiopicrin and amarogentin. The bitter taste of these can be detected even when diluted 50,000 times. Besides stimulating secretion of saliva in the mouth and hydrochloric acid in the stomach, gentiopicrin may protect the liver. Gentian is used to treat poor appetite and indigestion. An open study shows that gentian tincture inhibits the feeling of fullness after eating, suggesting it could improve poor appetite

 Constituents of Gentian root:

 The dried Gentian root of commerce contains Gentiin and Gentiamarin, bitter glucosides, together with Gentianic acid (gentisin), the latter being physiologically inactive. Gentiopicrin, another bitter glucoside, a pale yellow crystalline substance, occurs in the fresh root, and may be isolated from it by treatment with boiling alcohol. The saccharine constituents of Gentian are dextrose, laevulose, sucrose and gentianose, a crystallizable, fermentable sugar. It is free from starch and yields from 3 to 4 per cent ash.

 Constitution in brief: Glycosides (gentiopicroside and amarogentin are primarily responsible for its bitter taste). Alkaloids. Flavonoids. Terpenes. Minerals. Vitamins.

 Constituents of Gentian root: bitter principles of secoiridoid types (gentiopicrin, amarogentin, sweroside, swertiamarin); alkaloids (gentianine, gentialutine); oligosaccharides (gentianose); triterpenes; sugars (gentianose, gentiobiose), sucrose; polysaccharides (inulin, pectin); xanthones (gentisin, gentisein, isogentisin, gentioside, which impart the yellow colour to the root); phenolic acids (gentisic, caffeic, protocatechuic and others); traces of a complex volatile oil.

 Glycosides known as amarogentin and gentiopicrin are primarily responsible for the bitter taste of gentian. In addition, the plant contains several alkaloids (mainly gentianine and gentialutine), xanthones, triterpenes, and sugars. Aside from its action as a bitter stomachic, none of the other purported effects is well documented in human beings. Some experiments on small animals indicate that gentian may increase the secretion of bile; the alkaloid gentianine also exhibits anti-inflammatory properties.

 Amarogentin - Although present in much smaller quantities than gentiopicroside, amarogentin is the constituent largely responsible for the bitterness of gentian. It is 3,000 times more bitter than gentiopicroside, and, tasted at dilutions of 1 :50,000, it is possibly the most bitter substance on the planet.
