In general, biologically active polyphenolic compounds have indirect lipid lowering effects, antioxidant properties and they can also eliminate the accumulated toxic metal elements in the liver in cases of hyperlipidemy. Because of all these, we studied the effect of Beiqishen tea on altered lipid metabolisms, redox parameters and on liver metal contents. Although it was expected, there was not any liver protecting activity of the Beiqishen tea extract in the hyperlipidemic rat model, which was proved by biochemical and morphological studies. The reason for our expectation was the significant polyphenol content of Beiqishen tea. Although, the detoxifying activity of tea polyphenols could be observed in hyperlipidemy, at the same time toxic metal element content (As, Mo, Ni, Pb and Cr) of the tea infusion accumulated in the liver in both normo- and hyperlipidemic rats.
