3. 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.

4. 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.

8. 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.

9. 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.

17. 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

23. 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.
