Abstract

Objective: To assess antihypertensive and cardio protective effects of the Convolvulus arvensis root powder in N^G-nitro-L-arginine methyl ester (L-NAME) induce hypertension in Female Swiss albino mice. 

Methodology: Female Swiss albino mice were divided into four categories. Control, 2% gum acacia L-NAME (40 mg/kg orally), CA (500 mg/kg orally) + L-NAME (40 mg/kg orally), L-arginine (100 mg/kg orally) + L-NAME (40 mg/kg orally) were given for 1 month. On 29^th day serum marker enzymes, cholesterol and hemodynamic parameters (systolic and diastolic BP) were measured and cardiac histology was performed. CA root powder was characterized by HPLC. 

Result: Systolic blood pressure level was raised by L-NAME (p<0.001). In both of the drugs treated groups, systolic and diastolic blood pressure level reduced significantly (p<0.001) compared to L-NAME group. In the L-NAME group significantly (p<0.01) elevated cholesterol was reduced (p<0.05) by CA root powder treatment. In the L-NAME group, inflammation and necrosis (0-35%) were present in the heart, whereas there was no change in the myocardium of CA and L-arginine treated mice. Vitexin, Orientin and Isoorientin were identified in the Methanolic extract of CA powder. 

Conclusion: The cardio-protective activity in CA and L-arginine treated mice, was evaluated by presence of the inflammation in the heart, absence of necrosis and remarkable depletion in Serum cholesterol parameters. Inhibition of oxidation activity by Orientin and Isoorientin appears to lessen the L-NAME induced damage. It is concluded that CA root extract possess antihypertensive and cardio protective activity.
