The Hypolipidemic and Antiobesity Effects of Puerh

Recently, research on the biomedical activity of pu-erh tea has focused on its antibacterial, antioxidative, lipid-lowering, and antiobesity effects . Many in vitro studies have shown that pu-erh tea has antioxidative activity. Lin et al. 8 reported that the water extract of pu-erh tea (100 ^g/ml) can protect the plasmid DNA from strand breakage induced by the Fenton reaction as well as the control, regardless of total catechin content Duh et al 4 reported that pu-erh tea water extract with less cat-echins (8 . 01 mg/ml), compared to green tea water extract with more catechins (79 . 1 mg/ml), could still chelate metal ions, scavenge DPPH radicals, and decrease nitric oxide production in lipopolysaccharide-activated RAW 264.7 macrophages .

Sano et al .9 and Kuo et al . 3 demonstrated lipid-lowering effects of pu-erh tea in Wistar rats in a 16-week feeding study and in Sprague-Dawley rats in a 30-week feeding trial

The suppression of lipogenesis by oolong, black, green, and pu-erh tea leaves in rats has been demonstrated by suppression of plasma triacylglycerols (TAG), cholesterol, and low-density lipoprotein (LDL) cholesterol in the experimental Sprague-Dawley rats 3 The results indicated that pu-erh tea and oolong tea could lower the levels of plasma TAG more significantly than those of green tea and black tea . Meanwhile, pu-erh tea and green tea were more efficient than oolong tea and black tea in lowering the levels of total cholesterol
