ABSTRACT
Background: Diabetes is almost growing health concern worldwide and now emerging as an epidemic world over. Recently, full attention is being paid to the study of natural products as potential antidiabetics. Objective of the study was to evaluate the antidiabetic effect of hydroalcoholic leaf extract of Annona squamosa (HAEAS) plant in alloxan monohydrate induced diabetic albino rats.Methods: Almost a 30 Albino rats with 150- 200 grams weight were weighed and grouped into 5 equal groups taking 6 rats in every group. Group A served as normal control, Group B as diabetic control, received alloxan monnohydrate. Group C and D was received alloxan + HAEAS suspension at 350 and 700 mg/kg doses orally respectively, Group E was given alloxan + standard drug (Glibenclamide 5mg/kg) suspension for 28 successive days and the effect of HAEAS on blood sugar(BS) levels was measured at regular intervals. At the end portion of this investigational research study samples of blood were collected from all rats on 0day (initial), after 72 hrs and after 28th day (29thday) of given test drug HAEAS treatment for biochemical estimation of BS and the BS values were observed.Results: The present research study revealed that HAEAS leaves has antidiabetic effect against alloxan monohydrate induced diabetic rats on i.p. alloxan injection at 150mg/kg.b.w. and confirms that on i.p. alloxan injection causes a significant rise off BS in untreated albino rats when compared to control group. Diabetic rats treatment with HAEAS leaves for 28 days caused dose a dependent fall in BS values. Glibenclamide treated diabetic rats also showed a significant (P <0.00) fall in BS content after 28 days of treatment.Conclusions: This research study confirms that HAEAS leaves has shown significant antidiabetic effect at 350 and 700 mg/kg. b.w. doses in alloxan monohydrate induced diabetic rats.
ABSTRACT
Allophylus cominia (L) Sw (Sapindaceae), is one of the most popular medicinal plant in Cuba. It is traditionally used in the treatment of diabetes. The aim of this study was to investigate the effect of A cominia leaves aqueous extract in a type 2 diabetes model induced by streptozotocin treatment in neonatal rats. Two experiments was executed: at 6 weeks old rats, before starting the plant evaluation, and at 11 weeks old rats, after the oral administration daily of three doses 0.25, 0.5 and 1.0 g/kg of A cominia aqueous extract during 3 weeks and plasma blood glucose level was evaluated. At 6 weeks old rats, the group of diabetic animals showed significant f diabetic animals treated w0.05). Only the groups treated with 0.5 and 1.0 g/kg of A cominia extract showed a recovery of normal glycaemic values. Hence, it can be concluded that aqueous extract from A cominia leaves has antidiabetic properties and may be effective in the type 2 diabetes treatment.
Allophylus cominia (L) Sw (Sapindaceae), es una de las plantas medicinales más populares en Cuba habiendo sido empleada tradicionalmente en el tratamiento de la diabetes. es una de las plantas medicinales Cubanas más populares. Esta ha sido empleada tradicionalmente en el tratamiento de la diabetes. El objetivo de este estudio fue investigar el efecto del extracto acuoso de hojas de A cominia en un modelo de diabetes tipo 2 inducida por tratamiento con estreptozotocina en ratas neonatales. Se realizaron dos experimentos: a las 6 semanas de vida de las ratas, antes de comenzar la evaluación de la planta, y a las 11 semanas de vida de las ratas, después de la administración oral diaria de tres dosis de 0.25, 0.5 y 1.0 g/kg del extracto de A cominia durante 3 semanas y se evaluó la concentración de glucosa en sangre. A las 6 semanas de vida de las ratas, el grupo de animales diabéticos mostró un decrecimiento significativo en los valores de glucosa en sangre y el peso corporal comparado con el grupo control (p < 0.05). A las 11 semanas de vida de las ratas, los grupos de animales diabéticos tratados con el extracto acuoso de A cominia decrecieron significativamente las concentraciones de glucosa en sangre comparado con el grupo diabético no tratado (p < 0.05). Solamente los grupos tratados con 0.5 y 1.0 g/kg del extracto de A cominia mostraron una recuperación de los valores glicémicos normales. Por tanto, se puede concluir que el extracto acuoso de hojas de A cominia tiene propiedades antidiabéticas y puede ser eficaz en el tratamiento de la diabetes tipo 2.

Objective: To investigate the antidiabetic properties of aqueous extract of stem bark of Afzeliaafricana (A. africana) and its beneficial effect on haematological parameters in streptozotocin induced diabetic rats. Methods: A total of 30 rats including 24 diabetic and 6 normal rats were used for this study. Diabetes was induced in male Wistar rats by intraperitoneal injection of streptozotocin. After being confirmed diabetic, animals were orally treated with distilled water or extracts at 100 or 200 mg/kg body weight daily for 10 days. The haematological parameters including red blood and white blood cells and their functional indices were evaluated in diabetic treated groups compared with the controls. Results: The extract significantly reduced the blood glucose levels while the best result was obtained at 200 mg/kg body weight. The feed and water intake in diabetic rats were significantly reduced while weight loss was minimized at both dosages. Similarly, the levels of red blood, white blood cells and their functional indices were significantly improved after extract administration at both doses. Conclusions: It can be concluded that the aqueous extract of bark of A. africana possesses antihyperglycemic properties. In addition, the extract can prevent various complications of diabetes and improve some haematological parameters. Further experimental investigation is needed to exploit its relevant therapeutic effect to substantiate its ethnomedicinal usage.
