Ellagic acid: it is not gallic acid dimeric derivatives, a polyphenol two lactone. It not only can exist in the free form, and are based more on condensed form (ellagitannin, glycosides, etc.) exist in nature. Ellagic acid and ferric chloride color reaction was blue, yellow case of sulfuric acid, the the Greiss-meger reaction was positive, but also easy to combine with metal cations such as ca2, M. Pure ellagic acid is a yellow needle-like crystals, melting point (pyridine) greater than 36,012, slightly soluble in water and alcohol soluble alkali, pyridine, and insoluble in ether.
Tanning Hua acid (2,3,7,8-tetrahydroxy benzopyrano5, 4,3 a cdebenzopyran-5, 10-dione) is widely exist in a natural polyphenol components in a variety of soft fruit, nuts and other plant tissues, ellagic acid and ferric chloride color reaction was blue, yellow case of sulfuric acid.
Ellagic acid showed significant inhibition of chemically induced cancer and a variety of other cancer, especially colon cancer, esophageal cancer, liver cancer, lung cancer, tongue and skin tumors have a good inhibition.
