In order to study the effects of Typha angustata on hyperlipidemia, we divided the rats into three groups(normal group, control group & sample group) and perfomed the experimental research. Hyperlipidemia rats were induced by Triton WR-1339 for 3days. The sample group was administerd the extract of Typha angustata 2ml／200g for 3 days and control group was administerd equal dose of saline. And then we measured the amount of serum Total cholesterol, Triglyceride, LDL-cholesterol, HDL-cholesterol, and Phospholipid. The results were as follows: 1. Typha angustata showed decreasing effects on Total cholesterol, Triglyceride, LDL-cholesterol, and Phospholipid levels in serum significantly(p<0.01) 2. Typha angustata showed and showed increasing effects on HDL-cholesterol level in serum significantly(p<0.05). According to the above results, Typha angustata showed significant decreasing effects on hyperlipidemia, and it is considered that it is appropriate to apply for hyperlipidemia.
