Polyphenol is a much abused term. Strictly speaking, 90% of tea polyphenols are catechins, so the two terms are almost synonymous. However, for reasons I do not yet understand, this word has been used interchangeably with green tea extract.A standardized green tea extract contains only about 30% catechins.owever, what makes these catechins important is not their potency, but their abundance. About half of the catechin content of tea is EGCG. Just a small quantity of tea leaves will steep many cups of tea. It is this relative abundance that makes green tea special.

From Wikipedia, the free encyclopedia. A certified pre-owned car or CPO is a type of used car. Most often late-model, they differ from other used cars by having been inspected, refurbished, and certified by a manufacturer or other certifying authority.They also typically include an extended warranty, special financing, and additional benefits.actory CPO cars are generally five years old or newer and have less than 80,000 miles. They often cost more than vehicles certified by independent authorities, and are higher priced than a non-certified used vehicle. Independent programs can represent good value and an alternative to an OEM program.
