Oligonol, a Low-molecular Weight Polyphenol Extracted from Lychee Fruit, Modulates Cholesterol Metabolism in Rats within a Short Period.

There is growing research interest in the hypocholesterolemic effect of various food components such as polyphenols. In this study, we examined the effects of oligonol-a low-molecular weight polyphenol extracted from lychee fruit-on cholesterol metabolism in rats under short-term administration. Administration of oligonol for 3 days significantly increased cecum weight and decreased cecal n-butyric acid concentrations in rats.
