Ellagic Acid
A fused four ring compound occurring free or combined in galls. Isolated from the kino of Eucalyptus maculata Hook and E. Hemipholia F. Muell. Activates Factor XII of the blood clotting system which also causes kinin release; used in research and as a dye.
Hydrolyzable Tannins
Polymeric derivatives of GALLIC ACID that are esters of a sugar.
Punicaceae

Terminalia
A plant genus of the family COMBRETACEAE. Members contain arjunin, an ellagitannin (TANNINS).
Fragaria
A plant genus of the family ROSACEAE known for the edible fruit.
Lagerstroemia
A plant genus of the family LYTHRACEAE. Members contain lagertannin and have hypoglycemic effects.

Gallic Acid

Tannins
Polyphenolic compounds with molecular weights of around 500-3000 daltons and containing enough hydroxyl groups (1-2 per 100 MW) for effective cross linking of other compounds (ASTRINGENTS). The two main types are HYDROLYZABLE TANNINS and CONDENSED TANNINS. Historically, the term has applied to many compounds and plant extracts able to render skin COLLAGEN impervious to degradation. The word tannin derives from the Celtic word for OAK TREE which was used for leather processing.

Factor XII
Stable blood coagulation factor activated by contact with the subendothelial surface of an injured vessel. Along with prekallikrein, it serves as the contact factor that initiates the intrinsic pathway of blood coagulation. Kallikrein activates factor XII to XIIa. Deficiency of factor XII, also called the Hageman trait, leads to increased incidence of thromboembolic disease. Mutations in the gene for factor XII that appear to increase factor XII amidolytic activity are associated with HEREDITARY ANGIOEDEMA TYPE III.
Caesalpinia
A plant genus of the family FABACEAE. The common name of "Bird-Of-Paradise" is also used for other plants such as Heliconia (HELICONIACEAE) and Strelitzia (STRELITZIACEAE) and some birds. The common name of "Cat's-Claw" is more often used with UNCARIA. The common name of "Pernambuco" also refers to a state in Brazil. Furanoditerpenoid lactones and caesalpin are produced by members of this genus.
