Anti-Hyperlipidemic Activity of Ursolic Acid Derivative Obtained from Lantana Camara

Anjali Singh, Chhater Singh*

Mahaver College of Pharmacy Meerut, India

Abstract: Lantana camara is to be a tackler in Indian ethanopharmacology. It is found commonly every where even on waste land, road side, dry places and spread vigorously on cultivated ground. The aim of present study is to evaluate pharmacological effect ursolic acid steroyl glucoside obtained from lantana camara on lipid profile of high fat diet (58%) induced hyperlipidemia. Administration of high fat diet increase the lipid profile of the animals significantly as compared to normal control. Treatment with the ursolic acid steroyl glucoside for 12 weeks. Decreased the lipid parameters as compared to disease controls. The study shown promising effect in lowering of body weight and by other pharmacological parameter. we concluded that ursolic acid derivative of lantana camara have a potent anti hyperlipidemic activity.

Keywords: hyperlipidemia, lantana camara, ursolic acid

1. Introduction

Hyperlipidemia refers to elevated levels of Total cholesterol, TG, HDLs in the blood, and is also identified as dyslipidemia, to describe the manifestations of different disorders of lipoprotein metabolism.

Although elevated low density lipoprotein cholesterol (LDL) is thought to be the best indicator of atherosclerosis risk [1], Cholesterol, triglycerides, and phospholipids are the major lipids in the body. They are transported as complexes of lipid and proteins known as lipoproteins.

Plasma lipoproteins are spherical particles with surfaces that consist largely of phospholipid, free cholesterol, and protein and cores composed mostly of triglyceride and cholesterol ester [2]. It is major cause of atherosclerosis and atherosclerosis related condition like coronary heart disease (CHD), ischemic cerebrovascular disease, peripheral vascular disease and pancreatitis [3,4].

The etiology of hyperlipidemia can be classified into primary and secondary causes.

1. Primary due to [5]:

• A single gene defect: is familial and called ‘monogenic’ or genetic and

• Multiple genetic, dietary and physical activity related causes: ‘polygenic’ or malfactorial.

2. Secondary:

• Associated with diabetes, myxoedema, nephritic syndrome, chronic alcoholism, drugs (corticosteroids, oral contraceptives, beta blockers).

• Cholesterol and other fatty substances combine in the bloodstream and deposited in blood vessel forming plaque. Which leading obstruction of blood flow and causing heart attack, stroke and atherosclerois.

Lantana camara Linn. is regarded both as a notorious weed and a popular ornamental garden plant and posseses various uses in folk medicine in many parts of the world. [6] Lantana camara, also known as Spanish Flag or West Indian lantana, is a species of flowering plant in the verbena family; Verbenaceae. The plant has reported as anticonvulsant [7], anticancer [8,9], antiulcer [10], antioxidant [11], anti-diabetic [12,13], antifungal, antibacterial [14,15], anti-feedant, larval mortality/repellency [16,17], anti-motility [18], analgesic and anti-inflammatory [19] activities.

2. Material and Method

The fresh leaves of plant Lantana camara were collected from plant for extraction and then isolation of ursolic acid derivative from this plant with the help of column chromatography.

Albino rats of weighing 150-200 gm obtained from the animal house of the Faculty of Medicine, University of DIPSAR. Standard drug (atorvastatin) was purchased from local market.

3. Experimental Methodology

3.1. Experimental Methodology

The animals were kept in individual ventilated cages under the conditions of 22±25°C and a 12-hour light-dark cycle, with free access to food and water. The experimental protocol was approved by Institutional Animal Ethical Committee as per the guidance of committee for the purpose of Control and Supervision of Experiments on Animals (CPCSEA), Ministry of Social Justice and Empowerment, Government of India and approval no. is SIP/IAEC/09/2011.

The experimental design is depicted in the Figure 1 to Figure 3 below. In this experiment design following an acclimatization period of 4 weeks and 7 week study with purified diet, animals are divided in 6 groups, each group had 6 animals.

Group: 36 Animals will be divided in to 6 groups, 6 animals in each group.

3.1. Evaluation Parameters

• Body weight variation

• Lipid profile parameters: Cholesterol, Triglyceride, LDL, HDL, VLDL.

• Liver function tests: Bilirubin (direct, indirect), SGOT, SGPT, Alkaline phosphatase, Total protein, albumin, globulin, GGT.

• Hematology: HB, TLC, TRBC, PCV, Platelets count, ESR, lipase.

3.2. Blood Sampling and Serum Extraction

Blood was collected from all groups directly from retro orbital plexus after anaesthetization by a mixture of cholroform-ether (2:3) at the end of protocol period. Serum was separated after coagulating blood for 30 min. and centrifuged at 1500 rpm for 20 min., serum was then separated and was used for estimation of biochemical parameters.

3.3. Statistical Analysis

All the data is expressed as mean± S.E.M .Significant difference between the mean values were statistically analyzed using one ay analysis of variance. the values less than 0.001 were considered significant.

4. Results and Discussion

4.1. Variation of Body Weight

The observation of biological parameters in the body weight of rats, there is slight increased in the body weight of all rats in drug controlled, in comparison of HFD+STD, HFD+TD, ND+STD, ND+TD increased and NC is decreased.

5. Conclusion

The present study provides evidence for the ability of UASG, to decreased the lipid levels of high fat diet induced hyperlipidemia in wistar rats. The UASG also subjected to a toxicity testing and it was tested up to a high concentration of 10 mg /kg, orally(3 times per day) evaluated in the present study . Even at this dose the extract did not produce signs of toxicity or treatment related adverse effects in the tests for anti hyperlipidemia activity. This study clearly suggests that UASG is a potent hypolipidemic in rats.
