Preclinical Antihyperlipidemic Effect of Herbalism against Lipid Elevating Agents: A Review

Abnormal increase in the level of more than any one of the lipoproteins such as triglycerides, cholesterol, LDL or VLDL in the bloodstream can be defined as hyperlipidemia. It is the greatest world is often overused so, use “the most significant” instead of the greatestrisk factor of coronary heart attack and stroke. This review emphasizes on some herbal medicinal plants with their extracts, including Glycyrrhiza glabra,Legenaria siceraria,Medicago sativa,Curcuma longa,Curatella americana, Glycine max, Hibisus rosa-sinesis, Hibisus sabdariffa, Cinnamomum tamala, Withania somnifera, Cassia auriculata, Cynaras scolymus, Eugenia jambolana, Adenanthera pavonia, Garcinia cambogia, Terminalia chebula, Ixora coccinea, Carica papaya, Lycimum barbarum, Bauhinia purpurea, Syzygium alternifolium, Vitex negundo, Piper longa, Moringa oleifera, Zingiber officinale, Trigonella foenum graecum, Carum carvi, Gloriosasuperba, Ficus infectoria, Ficus glomerata for anti-hyperlipidemic potential. Decrease in the levels of these lipoproteins like, triglycerides (TG), Total cholesterol (TC), Very low density lipoprotein (VLDL) and low-density lipoprotein (LDL)includes some mechanisms actions of these medicinal plants observed in triton-x, cholesterol, high fat diet, Poloxamer-407, Dexamethasone and alloxan-induced in-vivo and in-vitro models. Accordingly, this review provides numerous evidenceswhichindicatethat these medicinal plants can be usedfor treating and preventinghyperlipidemia and related complications.

Hyperlipidemia is a chaos of lipid metabolism produced bytherise of plasma concentration of the different lipid and lipoprotein portions, which are the source of heart disease. It characterizedas the elevation of serum TC, TG, VLDL, LDL and HDL, which are responsible for various complications likeheart attack, coronary artery syndrome, stroke, atherosclerosis, myocardial infarction and pancreatitis. Hyperlipidemia can be either primary or secondary type; the primary syndrome might be treated by hypolipidemic drugs, however, secondary induced by diabetes, hypothyroidism or renal lipid nephrosis which treated by treating the natural disease respectably than hyperlipidemia. 1 Genetic disorder and way of life diet wealthy in calories, fat, and cholesterol assume a vitalrole to cause dyslipidemia around the world. 2 The primary factor responsible for hyperlipidemia includes sedentary lifestyle and changing habits in which the most vulnerable factor includes poor diet, for example,lipoprotein intake of more than 40 percent of total calories, intake of saturated fat more than 10 per cent of total calories; and ingestion of cholesterol more than 300 milligrams per day. 3 For enormous hyperlipidemia number of manufactured medications available, not a bit is useful for all lipoprotein disorder, and every drug connected with various side effects. So, presently a day different materials are search from natural sources with the severity of less toxic, less expensive, and provide better safety and efficacy on a long agepractice. Characteristic items from plants are a rich wellspring of medication utilized for quite a long time to treat different disease. 4 Hyperlipidemia, a clinical state can be defined as increase in either all lipoproteins or any one of them in the blood. 5 The lipid metabolism is synchronized in many various ways. Enzymes are the most significant regulators of lipid metabolism, for example, 3-Hydroxy-3methylglutaryl coenzyme which is a reductase enzyme responsible for the biosynthesis of cholesterol. 6 However, increase in thelow-density lipoprotein cholesterol (LDL-C) is the major lipid responsible for causing atherosclerosis. Dyslipidemia occurs due to significant abnormal amount of total cholesterol (TC), triglycerides (TG), or low levels of high-density lipoprotein (HDL).Hyperlipidemia is a medical just as social issue, particularly connected with diabetes mellitus results in increased mortality rate and morbidity. The major factors leading to hyperlipidemia includes atherosclerosis,which however results incerebrovascular and ischemic coronary heart disease. 7 Various allopathic hypolipidemic drugs like statins are obtaining in the market, but they cause various adverse effects like hyperuricemia, looseness of the bowels, myositis, hepatotoxicity, and so on. As they are for the most enzyme inhibitors, so they may inhibitother grave enzymes in the body. Additionally, statins are intake on a long-term basis, so it causes chronic toxic effects over a lifetime use. 8

Individuals Drugs Glycyrrhiza glabra
Glycyrrhiza glabra belongs to family Fabaceae. The main chemical constituents includes saponins, glycyrrhizin, triterpene and glycyrrhetic acid. It is used as ananti-inflammatory, mild laxative, antiarthritic, antiviral, antiulcer,, antibiotic, memory stimulant, antitussive, aphrodisiac, antineoplastic, anticholinergic, antidiuretic, antimycotic, estrogenic, antioxidant, anticaries agent, hypolipidemic agent. 9 The results concluded that the level of TG, TC, and LDL-C in serum (P<0.05) was prominently elevated in HFD animals when compared with the control group. However, the ethanolic root extract of Glycyrrhiza glabraat a dose of 400mg/kg when administered to animals showed a prominent increase in the plasma HDL-C in animals treated with Glycyrrhiza glabra extract when compared to HFD rats. In this study, the highfat diet used contains saturated fatty acids which elevates the effect of HMG-CoA reductase enzyme due to increased availability of acetyl CoA thereby resulting in increased cholesterogenesis rate. 10

Lagenaria siceraria
Lagenaria siceraria belongs to family Cucurbitaceae. It is used for treating different conditions, like jaundice, congestive heart failure (CCF),ulcer, piles, diabetes, insanity,colitis, skin disease, and hypertension. The pulp of the fruits is used both as laxative and emetic. It is also used for its cooling effect, antibilious, as diuretic and pectoral properties. The driedpulp can also be used for treatinginsomnia and rheumatism. 11 The results demonstrate that Lagenaria siceraria obtains the prominent antihyperlipidemic potential, which may be because of secondary metabolites as saponins, phenolic compounds, and flavonoids present in the extract of leaf. Flavonoids present in the extract may increase Lecithin Acyl Transferase (LCAT) effects. LCAT is responsible for the regulation of blood lipids. LCAT is the principal enzyme responsible for the incorporation of cholesterol into HDLc. This may result an elevation in HDLc and transferring it back into LDLc and VLDLc. Afterwards,these are taken back in hepatocytes. It demonstrates that there is an inverse relationship between incidence of Coronary Artery Disease (CAD) and HDL-C levels. Saponins are also anti-hyperlipidemic. They exert their antihyperlipidemic effect through various mechanisms. Saponins reduce the intestinal absorption of cholesterol by binding with it and thus elevating its faecal elimination. 12

Medicago sativa
Medicago sativa, also known as alfalfa, which belongs to family Fabaceae. M. sativa is utilized as a food additive in the United States, North Africa, Russia and China due to their high vitamin content. It outcomes secondary metabolites, such as naphthoquinones, alkaloids, coumarins, isoflavones and saponins, that have nematocidal, cytotoxic and antimicrobial activity. 13 The methanolic extract, chloroform, ethyl acetate, petroleum ether, and butanol fractions of sprouts of M. sativa, demonstrate a prominent treatment-duration related reduce in the TG, TC, LDL and VLDL levels compared to the untreated diabetic rats in a level alike to those of reference hypolipidemic drug rouvastatin. The high content of omega -3 fatty acids (2.1%) and phytosterols (28.3%) in oil ether portion might be the reason for the hypolipidemic activity of petroleum ether part,and the total extract of M. sativa grows; as detailed previously, stigmasterol decreases plasma cholesterol levels and stop hepatic synthesis and intestinal absorption in the rats â-sitosterol has a reducing activity on hypercholesterolemia and omega -3 fatty acids have a diminishing effect on raised cholesterolemia in NIDDM patients. The investigation findings revealed that the methanolic extract of M. sativa grows applied antihyperlipidemic and improved antihyperglycemic activity in STZ diabetic hyperlipidemic rats. 14

A study on diabetic hyperlipidemic rats demonstrated that the serum TG level declined at the end of 4 weeks in Group IV and Group V rats administered with 300 mg/kg and 500 mg/kg body weight dose respectively. Serum TG level in Group IV was 109.0 ± 7.98, and in Group V was 94.33 ± 5.15 in examination with Group II rodents (diabetic hyperlipidemic control gathering) 136.33 ± 3.32. Mean estimation of serum HDL in Group I was 57.60 ± 5.67, Group II was 33.75 ± 2.25, Group III was 35.00 ± 2.23, and Group IV was 35.67.78 ± 2.41. The studied was noted that curcumin administration did not have any prominent activity on the mean value of serum HDL (P > 0.05). The study on diabetic hyperlipidemic rats was conducted and a notable increase in serum HDL levels in diabetic hyperlipidemic rats was observed, who received turmeric at a dose of 300 mg/kg and 500 mg/kg respectively, for four weeks. Activity of ethanolic extract of turmeric in a dose of 300 mg/ kg/day and 500 mg/kg/day decreased serum TC and serum TG. There was no prominent rise in serum HDL-C levels in Groups III, IV, V, and VI. 15

Curatella americana

The hypolipidemic activity demonstratesa noticeable elevation in the levels of triglycerides and total cholesterol. Other chemical constituents like, saponins also possess the potential to reduce the level of cholesterol in serum. However, it was observed that C. americana extract resulted in decreasing both the serum cholesterol and triglycerides level contributing towards management of hyperlipidemia. The extract also reduced the oxidative stress owing to the free radical scavenging activity thereby protecting against lipid peroxidation 16 .

Glycine max
Glycine max belonging to family fabaceae. Commonly, it is also known as soybean. It related to a modulation of the immune system, anti-oxidation, inhibition of carcinogenesis, and its capacity to bring down the cholesterol level. There are different soybean cultivars, yet black soybean demonstrated to be better than different varietiesbe cause of its higher capability to act as an antioxidant. The most significant therapeutic properties of black soybean include its capacity to acts as a detoxificant, antiinflammatory, and wellspring of the progress of the blood plasma profile. 17 The levels of LDL, VLDL, TG and TC highly prominently increased in the treated group (HCD alone) when compared with control groups (pÂ0.001 or pÂ0.01). The level of HDL was essentially diminished in the efficacy group in comparing with standard control (pÂ0.01). However, the administration of MEGM high dose at 400 mg/kgand MEGM low dose at 200 mg/kg respectively in two groups already treated with HCD showed prominent increase the reduced levels of HDL (pÂ0.001 and pÂ0.05; separately) when compared with the control group. 18

Furthermore, it assists in inducing abortion and providing treatment for headache.
The level of serum cholesterol and lipoprotein were markedly increased while the level of HDL reduced in the atherogenic diet and triton treated animals. Flowers ethanolic extract portion (500 mg/kg body weight) prominent decreased this level and increased HDL level when compared with the control group. The results revealed maybe due to enhanced activity of Cholesterol acetyltransferase: lecithin, which combines with free LDL and cholesterol into HDL and transferred back to intermediate-density lipoprotein and VLDL. The decreased level of triglyceride might be due to prevention of fatty acids lipolysis because of which they do not get converted to triglyceride. 19

Hibiscus sabdariffa

It isa well-known traditional medicinal plant, has various biological effects and pharmacological actions, including decreasing blood glucose and serum lipids levels. It used to treat various diseases, like diabetes mellitus.
The results demonstrate LH II prominent reversed the reduction in hepatic and skeletal muscle glycogen content seen in diabetic controls, possibly due to reducing glycogen phosphorylate and raised glycogen synthase activities. Elevated total lipids of liver and kidney in alloxan-induced diabetic rabbits may indicate a high synthesis of lipid and storage capacity, which may have caused araised in serum TGs and phospholipids. It is concluded that insulin deficiency causes a variety of disorders in metabolic and regulatory mechanisms that are responsible for lipid accumulation. The elevated level of total lipids in diabetic rabbits was because if impaired insulin secretion, which result in high mobilization off at from the adipose tissue to the plasma. 26
The petroleum ether part, n-butanol part, diethyl ether part and ethyl acetate fraction of ethanolic extracts of Adenanthera pavonina Linn prevented huge valuable rise in cholesterol at 400 mg/kg dose levels, individually when compared with the untreated control group. The ethanolic extract fractions of Adenanthera pavonina Linnreduce the triglycerides levels in comparison to that vehicle control rats. The treatment with Atorvastatin resulted in a slightly better activity than Adenantherapavonina Linn. These outcomes concluded that the numerous portions of ethanolic extract of Adenanthera pavonina Linnmight interlope with cholesterol biosynthesis as triton quickens the hepatic synthesis of cholesterol.

Extract drug at both the doses reduces prominent (p<0.01) the increase of VLDL and TGL when compared with group toxic group. In same test,the drug (100 mg/kg) raises prominent levels of (p<0.01) HDL when compared with control and toxic groups. Test drug has prominently reduced the ratio of TC/HDL and AI in the hyperlipidemic rats. Test drug showed more hypolipidemic effect on a higher dose and therefore produce dose-dependent effect. 41

Gloriosasuperba
Gloriosasuperba belongs to Liliaceae family. This drug is a valuable plant found in Africa and tropical Asia. It used an Anthelmintic, antiinflammatory, Analgesic, Oxytocic, Abortifacient, Mutagenic and Antimicrobial activities.
MEGS treated animals showed prominent (p<0.0001) inhibitory effect on serum LDL and TC levels. (Moreover, and regarding the liver, it displayed the prevention of lipid peroxidation and increased catalase). The results revealed increase in plasma cholesterol level after administration of Poloxamer-407 i.p. The effect produced might be due to inhibition of cholesterol 7a-hydroxylase, which facilitates cholesterol clearance and up-regulation of 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase. Inhibitory effect of this enzyme reduces the rate at which triglycerides breaks down into free fatty acids to produce increase in triglycerides level. 42

Ficus infectoria
