To clarify a high utilization of Leucaena as tropical plant resources, the study was investigated to effect of extracted solution from fermented Leucaena materials produced for Leucaena feedstuff on blood pressure, plassa lipid and pathological observation of main organs of two type of disease rats(spontaneously hypertensive rats : SHR and rats withfructose-induced hyperlipidenia : FHR).The Leucaena solution extracted with hot water(Leucaena tea)was used in this experiment, which solution was obtained from a silage prepared and oven dried in 120ﾟC. Miseosine in Leucaena leaf and stem materials was removed by the method mentioned above. In the experiment periodblood pressure, daily gain and watering intake of two type of rats watered freely for twelve weeks were measured periodically, compared to ones watered Oolong tea and tap water(control). After the end of experimental period, all the rats were collected blood and separated to plasma and serum to measure the content of total cholest … More erol(TC), HDL-cholesterol(HDL-C), triglycerid(TG)and phospholipid(PL), respectively.The results obtained were as follows.1)There were no remarkable differences between the chemical compounds of Leucaene and Oolong tea, except of fifty times of calcium content in Leucaena tea compared to Oolong tea.2)The high maximum blood pressure of SHR and FHR watered Leucaena tea or Oolong tea was reduced compared to control group.3)The contents of TC, HDL-C and PL in plasma in SHR group watered with Leucaene tea were a little higher than control. The same value of HDL-C/TC ratio was shown in respective group. It can be considered that there is no effect of Leucaena and Oolong tea on the cholesterol content. On the other hand, the contents of TC, HDL-C and PL in plasma of FHR group watered with Leucaena or Oolong tea were significantly lower than control. It is considered that the upward tendency of plasmalipid in FHR group is suppressed by being watered with Leucaena or Oolong tea.4)There is no effect of Leucaena tea to SHR from the observation of tissue with a microscope, but it is suggested that Leucaena tea reduce an accumulation of fat in liver in FHR group.

为阐明热带植物银合欢资源的开发利用价值，本实验研究了银合欢发酵原料提取液对两种病大鼠血压、血脂及主要脏器病理学的影响（自发性高血压大鼠：SHR和果糖诱导的高血压大鼠：在该实验中使用用热水提取的银合欢溶液（银合欢茶），该溶液从制备的青贮饲料中获得并在120 ℃下烘干。用上述方法去除银合欢叶和茎中的米雪苷。实验期间定期测定两种自由饮水大鼠的血压、日增重和饮水量，并与饮用乌龙茶和自来水的对照组进行比较。实验结束后，取血分离血浆和血清，测定总胆固醇含量 ...更多信息 结果表明：1）银合欢烯与乌龙茶的化学成分无显著性差异，除了银合欢茶的钙含量是乌龙茶的50倍外。2）与对照组相比，饮用银合欢茶或乌龙茶的SHR和FHR的最高血压降低。SHR灌服银合欢烯茶后血浆TC、HDL-C、PL含量略高于对照组。各组HDL-C/TC比值相同。可以认为银合欢和乌龙茶对胆固醇含量没有影响。而饮银合欢或乌龙茶的FHR组血浆TC、HDL-C和PL含量均显著低于对照组。认为银合欢茶或乌龙茶能抑制FHR组血浆脂质的上升趋势。4）银合欢茶对SHR组织的显微镜观察无影响，但提示银合欢茶能减少FHR组肝脏中的脂肪堆积。少
