Swertianolin is a xanthone that is bellidifolin in which a beta-Dglucopyranosyl residue is attached at position O-8 via a glycosidic linkage. It is isolated particularly from Gentiana campestris and Gentiana germanica. It has a role as an antioxidant, an EC 3.1.1.7 (acetylcholinesterase) inhibitor and a plant metabolite. It is a beta-D-glucoside, an aromatic ether, a monosaccharide derivative and a xanthone glycoside. It is functionally related to a bellidifolin. Swertianolin shows anti-acetylcholinesterase activity effects, it shows significant hepatoprotective effect in the liver damage model induced by alpha-naphthylisot hiocyanate. Swertianolin can scavenge superoxide and hydroxyl radicals with the studying method of the autoxidation of Pyrogallol and afenton.

Osthenol shows antitumor-promoting activity, it also has antifungal and antibacterial activities.Osthenol potently and selectively inhibited recombinant human monoamine oxidase-A (hMAO-A) with an IC50 value of 0.74 μM; it exhibited a highly potent inhibitory activity on 5alpha-reductase type I in LNCaP cells with an IC50 value of 0.1 microg/ml; it also exhibited inhibitory activity on COX-1 with the IC50 value of 64.3 microM. Osthenol is a hydroxycoumarin that is umbelliferone in which the hydrogen at position 8 has been replaced by a prenyl group. It has a role as an antifungal agent and a plant metabolite. It is functionally related to an umbelliferone.

Eugenitin is a member of chromones. It has a role as a metabolite.
