Gallic acid, catechin , epicatechin and ferulic acid are the main polyphenolics in pineapple peels. 35. Catechin was first isolated from the plant extract catechu, from which it derives its name.36. Curcumin, capsaicin, gingerol, and catechins have also been found to increase adiponectin expression. 37. The biosynthesis of catechin is shown below 38. Catechin is metabolized to protocatechuic acid ( PCA ) and phloroglucinol carboxylic acid ( PGCA ).39. Some new structures like theacitrin have been proposed in 1997 or in 2003 ( catechins depletion. 40. Scientists have long suspected that tea, which also contains catechins , may have a protective effect.
