Introduction Plant formulation and combined extracts of plants are used a drug of choice rather than individual. Various herbal formulations such as diamed, coagent db, Diasulin, and hyponidd, are well known for their antidiabetic effects. Polyherbal formulation of Annona squamosa and Nigella sativa is composed of medicinal plants (Table 1), which are traditionally used for antidiabetic and antihyperlipidemic activity. The present investigation was undertaken to study the effect of the polyherbal formulation of Annona sqamosa and Nigella sativa on lipidperoxidation and tissue lipid profile in streptozotocin induced diabetic rats. 7 September th ACC and ANRAP, Bangkok3

Research Background Polyherbal formulation of Annona squamosa and Nigella sativa on blood glucose, plasma insulin, tissue lipid profile, and lipidperoxidation in streptozotocin induced diabetic rats. Aqueous extract of Polyherbal formulation of Annona squamosa and Nigella sativa was administered orally (200 mg/kg body weight) for 30 days. The different doses of Polyherbal formulation on blood glucose and plasma insulin in diabetic rats were studied and the levels of lipid peroxides and tissue lipids were also estimated in streptozotocin induced diabetic rats. The effects were compared with tolbutamide. Treatment with Polyherbal formulation and tolbutamide resulted in a significant reduction of blood glucose and increase in plasma insulin. 7 September th ACC and ANRAP, Bangkok4

Experimental design In the experiment, a total of 42 rats (30 diabetic surviving rats, 12 normal rats) were used. The rats were divided into seven groups of six rats each after the induction of streptozotocin diabetes. 7 September th ACC and ANRAP, Bangkok8

Experimental design Group1: Normal treated rats Group 2:Normal rats given aqueous solution of Polyherbal formulation (200 mg/kg body weight) daily using an intragastric tube for 30 days. Group 3:Diabetic control rats. Group 4: Diabetic rats given aqueous solution of Polyherbal formulation (50 mg/kg body weight) daily using an intragastric tube for 30 days. 7 September th ACC and ANRAP, Bangkok9

Experimental design Group 5: Diabetic rats given aqueous solution of Polyherbal formulation (100 mg/kg body weight) daily using an intragastric tube for 30 days. Group 6: Diabetic rats given aqueous solution of Polyherbal formulation (200 mg/kg body weight) daily using an intragastric tube for 30 days. Group 7: Diabetic rats given aqueous solution of Tolbutamide (250 m g /kg body weight) daily using an intragastric tube for 30 days. 7 September th ACC and ANRAP, Bangkok10

Conclusion Polyherbal formulation of Annona squamosa and Nigella sativa, exert a significant antihyperlipidemic. This could be due to combined effect of Annona squamosa and Nigella sativa. Hence the antihyperlipidemic effect of polyherbal formulation of Annona squamosa and Nigella sativa in particular could be considered as of possible therapeutic value 7 September th ACC and ANRAP, Bangkok17

Lipid Peroxidation Most phospholipid liposomes contain unsaturated acyl chains as part of their molecular structure and susceptible to oxidative degradation. It can be minimized by the use of animal derived lipids like egg PC, which has less saturated lipids, use of light resistant containers, use of antioxidants are useful in minimizing oxidation. 7 September th ACC and ANRAP, Bangkok23
