Effect of Alhagi Maurorum or Gloularia Alypum on lipid profile of experimentally induced hypercholesteremic rats and on blood pressure of experimentally induced hypertensive rats

In some countries, a high percentage of the population relies on traditional plants for treating certain diseases. The aim of this study was to investigate the effect of G. alypum extract (GAE) and Alhagj marorum extract (AME) on lipid profiles in experimentally induced hypercholesteremic rats and on the blood pressure of experimentally induced hypertensive rats. Male Wistar rats weighing 200 - 300 g were divided into five groups: group 1 received a normal diet (negative control), group 2 received a high lipid diet containing coconut oil (10 g/kg/day), cholesterol (4 g/kg/day) and cholic acid (0.20 g/kg/day) (positive control), group 3 received a high lipid diet together with clofibrate (50 mg/kg/day), group 4 received a high lipid diet together with AME (200 mg/kg/day) and group 5 received GAE (200 mg/kg/day). The experiment continued for two weeks, then the rats were sacrificed and blood samples were collected for estimation of cholesterol, triglycerides, high-density lipoprotein and low-density lipoprotein. To induce hypertension, rats were divided into two groups (n = 8 in each group). Group 1 received normal saline (control) and Group 2 received dexamethasone (0.40 mg/kg, i.p.) for seven consecutive days. Later, the rats were anesthetized using thiopental and the carotid artery was cannulated for recording blood pressure. AME (40 mg/kg) or GAE (40 mg/kg) were injected through a cannula placed into the internal jugular vein at a dose volume of 0.1 ml. Systolic and diastolic blood pressure were measured before and after plant extract administration. The results showed that clofibrate GAE extract and ANE extract significantly decreased cholesterol, triglycerides, low-density lipoprotein and high-density lipoprotein as compared to high-lipid diet-treated rats. Data also indicated that administration of GAE or AME extract significantly decreased systolic and diastolic blood pressure in experimentally induced hypertensive rats. In conclusion, GAE and AME have antihyperlipidemic and antihypertensive activities and further investigation is needed to clarify the mechanism of these effects
