柳茶7．5～15．0g（生药）/kg灌胃能显著降低正常或高血脂大鼠血清TG，β－LP，TC，升高HDL－C水平。离体实验表明，柳茶可促进脂肪分解。与对照组比较柳茶可使大鼠血清FFA含量显著升高，脂肪细胞较小，光镜下有粘液样变性。表明柳茶有明显的调节脂类代谢的作用．

Liu Tea (Sibiraea angustata) at doses of 8.5 and 15.0g/kg ig coild redice TG, β-LP, TC and elevate HDL-C levels of normal of normal or hyperlipoidemia rat. In vitro experiments indcated that S.angustata may promote the eatabolism of FFA. The contents of FFA in rat serum showed significant elevation in S. angustata treated groups as compared with the control. In addition, fat cells were smaller in S. angustat treated rats and mucoid changes could be seen under microscope. These results suggested that S. angustat could iegulate the metabolism of lipoid.
