Summary
The administration of tea polyphenol (TPP) diet containing 1.0% TPP to rats for 18 months significantly suppressed the increase of TBARS level in the plasma. The levels of total cholesterol (TC) and phospholipids (PL) in the plasma were also lowered. Positive correlations existed between the TBARS and triglyceride (TG), TC or PL levels in the plasma of rats 12 months after the feeding of TPP diet.
TPP especially, (-)-epigallocatechin gallate (EGCG) and (-)-epicatechin gallate (ECG) were much more effective than BHT, vitamin E or C in inhibiting the Cu2+ mediated oxidative modification of low density lipoprotein (LDL). EGCG strongly inhibited cholesterol ester oxidation and apolipoprotein B-100 fragmentation of LDL.
