将４５只已形成高血脂模型的鹌鹑分为５组：①大剂量组：茶多酚，６０ｍｇ／ｋｇ·ｄ ；②中剂量组：茶多酚，３０ｍｇ／ｋｇ·ｄ；③小剂量组：茶多酚，１５ｍｇ／ｋｇ·ｄ，④烟酸组（阳性对照）：烟酸，５０ｍｇ／ｋｇ·ｄ；⑤模型对照组（阴性对照）：不给药。第⑥组为正常动物组。给药３ｗｋ。结果：茶多酚具有较强的降低血清ＴＣ、ＴＧ和ＬＤＬ－Ｃ水平的作用，ＴＣ／ＨＤＬ－Ｃ比值变化小，推测对ＨＤＬ－Ｃ水平影响不大。烟酸（５０ｍｇ／ｋｇ·ｄ）降脂作用较大，中剂量组弱，与小剂量组相仿。茶多酚三个剂量组间量一效关系不明显。
45 high-fat diets were divided into five groups: ① high-dose group: 60 mg / kg · d of tea polyphenols; ② middle-dose group: 30 mg / kg · d of tea polyphenols; Tea polyphenols, 15mg / kg · d, ④ niacin group (positive control): niacin, 50mg / kg · d; ⑤ model control group (negative control): no administration. The ⑥ group of normal animal group. Administered 3wk. Results: Tea polyphenols had a significant effect of lowering serum TC, TG and LDL-C levels, and the change of TC / HDL-C ratio was small. It was presumed that HDL-C level had no significant effect. Niacin (50mg / kg · d) lipid-lowering effect of larger, medium dose group is weak, similar to the low-dose group. The three dose of tea polyphenols dose-effect relationship is not obvious.
