Pancreatic lipase-inhibitory activity of the rhizome of Rhei Rhizoma and its antihyperlipidemic activity were measured. Rhei Rhizoma inhibited pancreatic lipase with $IC_{50}$ value of 6.5 mg/ml (triolein as a substrate). Rhei Rhizoma significantly inhibited serum TG level in corn oil feeding-induced mice, and serum TG and cholesterol in Triton WR-1339-induced hyperlipidemic mice. However, Rhei Rhizoma did not show the hypolipidemic activity in high cholesterol diet-induced hyperlipidemic mice. When in vitro pancreatic lipase-inhibitory and in vivo antihyperlipidemic activities of Whangryunhaedoktang (WT) and Chunghyuldan (CD), which is consisted of ingredients of WT and Rhei Rhizoma, were measured, CD exhibited more potent inhibitory activities than WT. Therefore these results suggest that antihyperlipidemic activity of Rhei Rhizoma and CD may be more or less originated from the inhibition of pancreatic lipase.

In the previous reports, we selected 80% MeOH extract of 7 herbs including Scutellariae Radix(SR), Paeoniae Radix Rubra(PRR), Moutan Cortex(MC), Angelicae Gigantis Radix(AGR), Crataegi Fructus(CF), Bambusae Caulis in Taeniam(BCT) and Cinnamomi Ramulus(CR), which exhibited the inhibitory effect on HMG-CoA reductase and DPPH free radical scavenging effect in vitro, and antihyperlipidemic effects on antihyperlipidemic rats induced by Triton WR 1339 in vivo. Among them, SR, MC, AGR and BCT showed significant suppression of elevated serum LDL-cholesterol level, and AGR and CF showed significant liver weight increase on high cholesterol diet induced hyperlipidemic mice. And, SR, PRR, AGR, BCT and CR significantly suppressed the elevated serum total cholesterol and triglyceride levels on corn oil induced hyperlipidemic rats. Then, in order to research new antihyperlipidemic agents from the oriental medicinal herbs, we chose SR, AGR, CR and BCT which have the antihyperlipidemic effect in vitro and in vivo, and those herbs were systematically fractionated with organic solvent. EtOAc fraction of SR, hexane fraction of BCT, AGR and chloroform fraction of CR exhibited remarkably inhibitory effect on HMG-CoA reductase activity.

Effects of Samhwangsasimtang aqua-acupuncture at gansoo($B_{18}$) and chungwan($CV_{12}$) on antihyperlipidemic and antioxidant were investigated in rat fed high fat diet. Concentrations of triglyceride, free fatty acids, lipoprotein and glucose in plasma showed a tendency to decrease in the aqua-acupuncture groups. In plasma lipid composition, total cholesterol and LDL- cholesterol showed a tendency to decrease in aqua-acupuncture groups, however the values of HDL-cholesterol showed no significantly different in the treatment groups. Concentration of thiobarbituric acid reactive substances(TBARS) in plasma and liver showed a low in the aqua-acupuncture groups. The values of glutathione peroxidase(GSH-Px) and catalase(CAT) activity showed a tendency to increase in aqua-acupuncture groups. However the values of superoxide dismutase(SOD) activity showed no significantly different in the treatment groups.

The present study was carried out to investigate the antihyperglycemic, antihyperlipidemic and antioxidant effect of chloroform and methanol extract of whole plant of Ichnocarpus frutescens (CEIF and MEIF) in streptozotocin (STZ)-induced diabetic rats. Administration of CEIF and MEIF orally at the dose of 200 mg/kg and 400 mg/kg body weight resulted in significant (P<0.01) reduction in blood glucose levels. The body weights were significantly (P<0.001) reduced in STZ-induced diabetic rats when compared to normal rats while the extracts significantly (P<0.01) prevented the decrease in body weight in the CEIF and MEIF treated rats. The study was further undertaken to evaluate the antioxidant and antihyperlipidemic potential of CEIF and MEIF in STZ-induced diabetic rats. The increased levels of lipid peroxidation in the liver tissues of diabetic rats were significantly reverted back to normal levels and a significant increase in activity of antioxidant enzymes such as superoxide dismutase, catalase and the level of reduced glutathione in the liver of diabetic rats after the treatment with CEIF and MEIF was noticed. These results clearly indicate that CEIF and MEIF exhibit significant antihyperglycemic, antihyperlipidemic and in vivo antioxidant activity in STZ-induced diabetic rats and the results were found to be in a dose dependent manner.

The objective of the study was to investigate the antihyperlipidemic activity of alcoholic extract of Pongamia pinnata Linn. (PPAE) leaves in rats fed with high fat diet (HFD). PPAE was administered orally in the divided doses of 250 and 500 mg/kg/day for 30 days in HFD fed rats. Body weights were observed and the analysis of serum lipid profile was carried out on day 30. Marked decrease in the body weight, total cholesterol (TC), triglycerides (TG), low density lipoprotein (LDL) and very low density lipoprotein (VLDL) whereas significant increase in the levels of high density lipoprotein (HDL) were observed after treatment with PPAE. However, PPAE in a dose of 250 mg/kg did not show significant (P < 0.05) increase in HDL levels. The PPAE also lowered TC: HDL-c and LDL: HDL-c ratios significantly suggesting it's antihyperlipidemic and cardioprotective potential. The present work reveals that PPAE at the dose of 500 mg/kg/day exhibited significant (P < 0.01) antihyperlipidemic effects.

Objectives: Dyslipidemia in diabetes mellitus is a significant risk factor for the development of cardiovascular complications. The aim of this study was to evaluate the effect of the ethyl-acetate fraction of an ethanolic extract from Streospermum suaveolens on lipid metabolism in streptozotocin (STZ)-induced diabetic rats. Methods: Diabetes was induced by intraperitonial injection of STZ (50 mg/kg). Diabetic rats were treated with an ethyl-acetate fraction orally at doses of 200 and 400 mg/kg daily for 14 days. On the $15^{th}$ day, serum lipid profiles, such as total cholesterol (TC), triglycerides (TG), low-density lipoprotein (LDL), and high-density lipoprotein (HDL), were estimated in experimental rats. The atherogenic (AI) and the coronary risk (CRI) indices were also evaluated. Results: The ethyl-acetate fraction at doses of 200 and 400 mg/kg significantly (P < 0.001) and dose-dependently reduced serum cholesterol, triglycerides and LDL, but increased HDL towards near normal levels as compared to diabetic control rats. The fraction also significantly (P < 0.001) lowered the atherogenic index (AI) and coronary risk index (CAI) in a dose-dependent manner. Conclusion: The present study demonstrated that the ethyl-acetate fraction of Stereospermum suaveolens exhibits a potent antihyperlipidemic activity in hyperglycemic rats and suggests that the plant may have therapeutic value in treating the diabetic complication of hyperlipidemia.

The present study was carried out to investigate the antidiabetic and antioxidant effect of methanolic extract of Berberis tinctoria leaves (MEBT), in streptozotocin induced diabetic rats. Oral administration of MEBT extract (150 mg/kg and 300 mg/kg) for a period of 14 days. Blood glucose levels, body weight food and liquid intake were measured on every $5^{th}$ day over a period of 14 days. In diabetic rats, MEBT at the dose of 150 mg/kg and 300 mg/kg body weight resulted in significant reduction in blood glucose levels. The study was further investigated to determine antioxidant and antihyperlipidemic potential of MEBT in streptozotocin (STZ) induced diabetic rats. These results suggest that the MEBT possess antidiabetic activity and is able to ameliorate biochemical damages in STZ induced diabetic rats and the results were found to be in a dose dependent manner.

Alloxan administration in rats is used as a model for non-insulin dependent diabetes mellitus (NIDDM). NIDDM is a multifactorial disease, characterized by hyperglycemia and lipoprotein abnormalities. In this study, we evaluated the antihyperglycemic and antihyperlipidemic effects of fermented Rhynchosia nulubilis (FRN) through the regulation of glucose uptake in alloxan-induced rats. Fermented R. nulubilis was administered orally for 28 d at 500 mg/kg of body weight. Body weight and food intake were monitored every day. Biochemical parameters were quantified after 4 week. In the diabetic + FRN group, body weight increased significantly and blood glucose concentrations decreased when compared to those of the diabetic group. After 2 hr of administration, the oral glucose tolerance test (OGTT) indicated a significant reduction in the diabetic + FRN group compared to diabetic group. The diabetic + FRN group experienced a significant reduction in total cholesterol, triglycerides, low density lipoprotein, coronary risk factors, and malondialdehyde concentrations, with significantly increased high density lipoprotein compared to those of diabetic group. These results demonstrate that fermented R. nulubilis possesses potent antihyperglycemic and antihyperlipidemic activity in alloxan-induced diabetic rats.

Active component was sought among three herb medicines, which are used in combination as a traditional medicine prescribed for patients with hyperlipidemia related diseases. Antihyperlipidemic effect of this remedy has previously been shown model by the authors on the animal model. Hyperlipidemia was induced on male Wistar rats by keeping them on high lipid diet for one week, as previously described by the authors. Blood lipid profile was verified on these rats by measuring total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL) and low density lipoprotein (LDL). Then, the diet was changed to normal. At the same time, methanol extracts of Scutellaris baicalensis Georg.(radix), Coptidis japonica Makino(rhizoma) or Rhei koreanum Nakai(rhizoma) were given on daily basis, and changes in the blood lipid profile were monitored for 4 weeks. Methanol extract of Scutellaris baicalensis Georg. significantly reduced the TC value, implying the in vivo antihyperlipidemic effect.
