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.

Asperulosidic acid has been recently used in chinese medicine as a useful drug against some tumors. It has anticlastogenic activity, since the anticlastogenic irridoids have an alpha-unsaturated carbonyl group, this structure is considered to play an important role in the anticlastogenicity. Asperulosidic acid can inhibit the seed germination and growth of seedlings of large crabgrass. Asperulosidic acid, and 6-O-(beta-D-glucopyranosyl)-1-O-octanoyl-beta-D-glucopyranose are effective in suppressing 12-O-tedtradecanoylphorbol-13-acetate (TPA)- or epidermal growth factor (EGF)-induced cell transformation and associated AP-1 activity. Asperulosidic acid is a glycoside and an iridoid monoterpenoid.

Jionoside B1 has immunosuppressive activity, it shows the hepato-protective activity in the H2O2 induced liver injury experiments.Jionoside B1 exhibits the obvious inhibition against aldose reductase.

Prunasin is a kind of enzyme inhibitors.

Glucosyringic acid has immunosuppressive effect, it can inhibit the proliferation of murine B lymphocytes in vitro.

Quercetagitrin is a glycoside and a member of flavonoids.

Betaine hydrochloride is a natural compound found in many foods and also an active methyl-donor which can maintain normal DNA methylation patterns, which has anti-hypoxic, hepatoprotective, sedative, antipyretic and analgesic effects. Betaine hydrochloride can increase the secreting of thyroxine (T3) and insulin and regulate the metabolism of organism by the hormones, thus it prompts fish growth and also improves intestine figuration.
