The present paper reviews the active natural principles and crude extracts of plants which have been experimentally studied for hyploipidemic activity in the last decades. Phytoconstituents with known structures have been classified in appropriate chemical groups The data are reported on their pharmacological activity, mechanism of action and other properties. This review also describes the inducing method of experimental hypolipidemic animals appeared in the literature.

The hypolipidemic effects of soybeam paste containing mycelia of Phellinus linteus, Cordyceps militaris, Ganoderma lucidum were evaluated in hyperlipidemic rats. Body weight of the rats fed with soybean paste containing mycelia of Ganoderma lucidum (ESG) were significantly lower than control group whereas, there was no significant difference in body weight in order diet groups. Food intake, food efficiency ratio, and liver and kidney weights were not significantly different among the diet groups examined. However, the spleen weight of ESG group was markedly lower than other groups. Significant decreases in serum total cholesterol, LDL-cholesterol and liver total cholesterol were also observed in all diet groups tested. All groups fed with soybean paste containing mycelia of mushroom were also observed in all diet groups tested. All groups fed with soybean paste containing mycelia of mushroom were almost equally effective in increasing plasma HDL level and decreasing the atherogenic index, whereas the ratio of HDL to total cholesterol was significantly increased in all experimental diet groups.

The hypolipidemic effect of exe-polymer produced in submerged mycelial culture of Hericium erinaceus (HE), Auricularia auricula-judue (AA), Flammulina veluripes (FV), Phellinus pini (PP), and Grifola frondosa (GF) was investigated in dietary-induced hyperlipidemic rats. The animals were administered with exe-polymers at the level of 100 mg/kg body weight daily for four weeks. Hypolipidemic effect was achieved in all the experimental groups, however, HE exo-polymer proved to be the most potent one, which significantly reduced the plasma triglyceride ($28.9\%$), total cholesterol ($29.7\%$), low-density lipoprotein (LDL) cholesterol ($39.6\%$), phospholipid ($16.0\%$), and liver total cholesterol ($28.9\%$) level, when compared to the saline administered (control) group. The results of the present investigation strongly demonstrate the potential of HE exe-polymer in combating hyperlipidemia in the experimental animals.

The hypolipidemic effect of the exe-biopolymer (EXBP) and endo-biopolymer (ENBP) produced from a submerged mycelial culture of Ganoderma lucidum was investigated in dietary-induced hyperlipidemic rats. Hypolipidemic effects were achieved in both the EXBP- and ENBP-treated groups, however, the former proved to be more potent than the latter. The administration of the EXBP (100 mg/kg body weight) substantially reduced the plasma total cholesterol, low-density lipoprotein (LDL) cholesterol, triglyceride, phospholipid levels, and atherogenic index by 31.0, 39.0, 35.4, 28.1, and 53.5%, respectively, when compared to the control group. The EXBP also lowered the liver total cholesterol, triglyceride, and phospholipid levels by 22.4, 23.1, and 12.9%, respectively. Furthermore, the high-density lipoprotein (HDL) cholesterol and ratio of HDL cholesterol to total cholesterol were significantly increased by as much as 24.2% and 47.6%, respectively.

The fructus of Gardenia jasminoides Ellis (GF) has been widely used as a natural colorant in Asian countries, and also as a Chinese traditional medicine for its homeostatic, antiphlogistic, analgesic, and antipyretic effects. In the present study, its main component, crocin, was fermented with lactic acid bacteria (LAB) and their antihyperlipidemic activity was measured. The GF extract, fermented GF (F-GF), crocin, and fermented crocin (F-crocin) significantly inhibited the increase of serum triglyceride (TG) level in corn oil feeding-induced triglyceridemic mice, as well as that of serum TG and total and LDL cholesterol levels in Triton WR-1339-induced hyperlipidemic mice. These agents also showed hypolipidemic activity in hyperlipidemic mice induced by high fat diet for 5 weeks. F-GF and F-crocin exhibited more potent hyperlipidemic effects than GF and crocin. The results suggest that the hypolipidemic effect of GF and crocin can be synergistically activated by LAB, and that F-GF and F-crocin may improve hyperlipidemia in clinic, compared with GF and crocin.

Hypolipidemic effect of biopolymers extracted from culture broth (CP), mycelia (MP), and fruiting bodies (FP) of Auricularia auricula-judae was investigated in dietary-induced hyperlipidemic rats. The experimental animals were administrated (100 mg/kg body weight) with different biopolymers, daily for 4 weeks. Hypolipidemic effects were achieved in all the experimental groups, however, FP was proved to be the most potent one. The administration of the FP reduced the plasma triglyceride, total cholesterol, low-density lipoprotein cholesterol, and atherogenic index by 24.3, 28.5, 36.4, and 40.9%, respectively, while increased the high-density lipoprotein cholesterol level (9.0%), when compared to the saline (control) administered group.

Tectorigenin and kaikasaponin III from the flowers of Pueraria thunbergiana showed potent hypoglycemic and hypolipidemic effects in the streptozotocin-induced diabetic rats. Intraperitoneal administration of these two compounds with 5 and 10 mg/kg, respectively, for seven days to streptozotocin-induced rats significantly reduced the blood glucose, total cholesterol, LDL- and VLDI-cholesterol and triglyceride levels when compared with those of control group. Glycitein in which 5-OH is unlinked and tectoridin (7-O-glycoside of tectorigenin) isolated from the flowers of P. thunbergiana did not improve hyperglycemia and hyperlipidemia. In addition, tectorigenin showed in vitro antioxidant effects on 1,1-diphenyl-B-pirylhydrazyl (DPPH) radical, xanthine-xanthine oxidase superoxide anion radical, and lipid peroxidation in rat microsomes induced by enzymatic and non-enzymatic methods. We further found that tectorigenin and kaikasaponin III protected the Vero cell line(normal monkey kidney) from injury by hydrogen peroxide. From these findings, it seems likely that the antioxidant action of tectorigenin and kaikasaponin III may alleviate the streptozotocin-induced toxicity and contribute to hypoglycemic and hypolipidemic effects.

The antihepatic and hypolipidemic activities and total lipid levels of water extract of Plantaginis Herba, used for respiratory and renal disorder in folk medicine, were evaluated in streptozotocin-induced diabetic rats. Diabetes was induced by a single injection of streptozotocin (50 mg/kg, i.ｐ.). Water extract of Plantaginis Herba recovered enzyme activities such as GOT, GPT, ALP and LDH increased by streptozotocin (STZ) treatment. This crude drug also suppressed the enhanced production of lipid in hyperglycemia. These results strongly suggest that Plantaginis Herba be a promising liver-protective and hypolipidemic agent.

In this study, we investigated a dose-dependent hypolipidemic and antioxidant effects of tocotrienol-rich fraction (TRF) from grape seeds. After induction of hyperlipidemia for 4 weeks, rats were supplemented with different dose (5, 25, and 50 mg/kg BW/day) of TRF for 1 week. Oral administration of TRF (50 mg/kg BW/day) decreased the plasma triglyceride (TG, 162.6 mg/dL), total cholesterol (TC, 83.7 mg/dL), low density lipoprotein-cholesterol (LDL-C, 20.3 mg/dL), malondialdehyde contents (MDA, 3.3 nmol/dL), and atherogenic index (AI, 2.0) compare to high-fat diet group. These data suggest that TRF supplementation has significant health benefits through the modulation of physiological functions that include various atherogenic lipid profiles and antioxidative status in hyperlipidemia.

The hypoglycemic and hypolipidemic effects of Allium victorialis (AV) leaf methanol extract were evaluated in a high fat diet (HFD) supplied mice. Changes on the serum glucose, total cholesterol, triglyceride, low density lipoprotein and high density lipoprotein were examined. The effects were compared with those of a group given 250 mg/kg of metformin. After 91 days of a continuous HFD supply, the mice were showed marked hyperglycemia and hyperlipemia. However, these hyperglycemia and hyperlipemia induced by the HFD were inhibited by the AV extract treatment at the three different doses (62.5, 125 and 250 mg/kg). The results suggest that the AV methanol extract is beneficial for improving the diet-induced hyperlipidemia and hyperglycemia in humans.
