induces relaxation in rat renal arteries; from the root of Pulsatilla chinensis; structure in first source

Date introduced: May 5, 2003

2.

Triterpenes

A class of terpenes (the general formula C30H48) formed by the condensation of six isoprene units, equivalent to three terpene units.

Year introduced: 1974

3.

Terpenes

A class of compounds composed of repeating 5-carbon units of HEMITERPENES.

4.

Saponins

A type of glycoside widely distributed in plants. Each consists of a sapogenin as the aglycone moiety, and a sugar. The sapogenin may be a steroid or a triterpene and the sugar may be glucose, galactose, a pentose, or a methylpentose.

5.

Organic Chemicals

A broad class of substances containing carbon and its derivatives. Many of these chemicals will frequently contain hydrogen with or without oxygen, nitrogen, sulfur, phosphorus, and other elements. They exist in either carbon chain or carbon ring form.

Year introduced: 1998

6.

Hydrocarbons

Organic compounds that primarily contain carbon and hydrogen atoms with the carbon atoms forming a linear or circular structure.

7.

Glycosides

Any compound that contains a constituent sugar, in which the hydroxyl group attached to the first carbon is substituted by an alcoholic, phenolic, or other group. They are named specifically for the sugar contained, such as glucoside (glucose), pentoside (pentose), fructoside (fructose), etc. Upon hydrolysis, a sugar and nonsugar component (aglycone) are formed. (From Dorland, 28th ed; From Miall's Dictionary of Chemistry, 5th ed)

8.

Carbohydrates

A class of organic compounds composed of carbon, hydrogen, and oxygen in a ratio of Cn(H2O)n. The largest class of organic compounds, including STARCH; GLYCOGEN; CELLULOSE; POLYSACCHARIDES; and simple MONOSACCHARIDES.

Year introduced: /metabolism was CARBOHYDRATE METABOLISM 1963-1965
