Swertiamarin (Swertiamaroside) is a common secoiridoid found among the members of Gentianaceae with anti-inflammatory, anticancer, hypoglycemic and hypolipidemic activities.

1. Swertianolin (Bellidifolin-8-O-Glucoside), mangiferin, rhodenthoside A-C, isoorientin, isovitexin, and amarogentin would serve as potential chemotaxonomic markers to differentiate Gentianaceae species. 2. Swertianolin and swertiamarin show significant hepatoprotective effect in the liver damage model induced by alpha-naphthylisot hiocyanate. 3. Swertianolin shows anti-acetylcholinesterase activity effects. 4. Swertianolin shows that it can scavenge superoxide and hydroxyl radicals with the studying method of the autoxidation of Pyrogallol and afenton.

Gentianine is an effective Swertiamarin derivative, which has anti-diabetic, antipsychotic, anti-inflammatory, hypotensive, diuretic and other effects, and has the potential to be developed into a safe antihypertensive drug.
