The present study was designed to evaluate the effects of aqueous extract of Thymus serpyllum on lipid profile and some liver enzymes level in the diabetic rabbit. Rabbits were made diabetic with a single intravenous injection of alloxan and were divided into groups. Group 1 and 2 served as normal and diabetic control, respectively. Group 3 and 4 were given standard drugs glibenclamide and acarbose respectively while Group 5 was treated with 500 mg/kg of extract for 30 days. Blood samples were taken on day 0 and 30. The extract significantly reduced the level of serum cholesterol, triglyceride, LDLs, VLDLs, alkaline phosphatase and transaminases without affecting the HDLs level. Total cholesterol/HDL-cholesterol ratio was significantly reduced as compared to diabetic control. It is conceivable that T. serpyllum possesses antihyperlipidemic and hepatoprotective effects in diabetic rabbit.

The present study was undertaken to evaluate antihyperlipidemic effect of aqueous methanolic extract of Berberis orthobotrys in experimentally induced hyperlipidemic animal models. Atorvastatin was used as standard drug. The crude extract (50 and 100 mg/kg) significantly prevented the increase in low density lipoprotein (LDL), very low density lipoprotein (VLDL), total cholesterol (TC), triglyceride (TG), atherogenic index and coronary risk index in high fat diet, cholesterol, fructose and olive oil-induced hyperlipidemic rat models whereas in ethanol treated mice, the extract reduced VLDL, TG and TC levels. The high density lipoprotein (HDL) level was significantly increased in high fat diet, olive oil and cholesterol induced hyperlipidemic rats. The reduction in serum level of above parameters with 100 mg/kg dose of extract was comparable with atorvastatin. It is concluded, that B. orthobotrys has atheroprotective and lipid lowering potential.

In the present study, the hepatoprotective activity of aqueous and ether extracts of Thymus linearis (250 and 500 mg/kg orally) was evaluated against carbon tetrachloride- and paracetamol-induced hepatic damage in mice. Serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) were assessed. Antioxidant activity of both the extracts was also determined using 1-1-diphenyl-2-picryl hydrazine (DPPH) scavenging method. The results indicated that both the extracts significantly produce a dose dependent reduction in serum levels of ALT, AST, ALP when compared to carbon tetrachloride-and paracetamol-treated groups. The maximum effect in all the parameters was observed at a dose of 500 mg/kg. The extracts also demonstrated a significant antioxidant activity. LD50 of both extracts was found to be a 1050 and 900 mg/kg respectively. It is conceivable that the hepatoprotective activity of T. linearis might be due to the presence of certain pharmacologically active compounds.

This study was conducted to investigate the diuretic potential of aqueous methanolic extract of Paspalidium flavidum in rats. The extract at doses of 10, 30 50 and 100 mg/kg was administered intraperitoneally in acute diuretic model. Furosemide (10 mg/kg i.p) was used as standard drug. Total urine volume and urinary excretion of electrolytes were measured. Preliminary phytochemi-cal tests were also performed using standard procedures. The extract exhibiteda significant dose dependent diuretic effect at all the doses when compared to control group. Urinary excretion of sodium was significantly increased by the extract while a significant increase in potassium excretion was only observed at higher doses. Phytochemical analysis illustrated that the extract contained compounds such as alkaloids, saponins, tannins, flavonoids, cardiac glycosides and reducing sugars. It is conceivable therefore that the aqueous methanolic extract of P. flavidum contain certain biologically active compounds that might be responsible for the diuretic activity.

In the present study crude powder and various extracts of Teucrium stocksianum were evaluated for antidiabetic effect in alloxan-induced diabetic rabbits. Crude extract significantly reduced blood glucose level of normal and diabetic rabbits. The results were comparable with standard drug gliben-clamide. Ethyl acetate extract (500 mg/kg) produced maximum decrease in blood glucose level among all the extracts and was selected for further study. Ethyl acetate extract significantly inhibited rise in glucose level in normal rabbits after an oral glucose load. The extract showed synergistic effect with different doses of insulin. Serum insulin level of diabetic rabbits was also significantly increased by the extract. HbA1c level was significantly (p

The present study was carried out to evaluate the seeds of Pennisetum glaucum for its blood pressure lowering effect in rats. Aqueous-methanolic extract of P. glaucum seeds in 250, 500 and 1000 mg/kg doses was studied in normotensive, egg-feed diet and glucose-induced hypertensive rats using non-invasive technique. The extract significantly (p?0.5 - p?0.001) decreased blood pressure and heart rate with maximum effect at 1,000 mg/kg dose. The extract was found to prevent rise in blood pressure of egg and glucose fed rats as compared to control group in 21 days study. The extract was safe in mice up to dose of 4 g/kg and sub-chronic toxicity study showed that there was no significant alterations in blood chemistry of extract treated rats. It is conceivable, therefore, that aqueous-methanolic extract of P. glaucum seeds has exerted considerable antihypertensive activity which may be due to the presence of phytochemical constituents.
