Aims: Arganimide A (4,4-dihydroxy-3,3-imino-di-benzoic acid) is a compound belonging to a family of aminophenolics found in fruit of Argania spinosa. The purpose of this study was to investigate the glucose and lipid lowering activity of Arganimide A (ARG A). Methods: The effect of a single dose and daily oral administration of Arganimide A (ARG A) on blood glucose levels and plasma lipid profile was tested in normal and streptozotocin (STZ) diabetic rats at a dose of 2 mg/kg body weight. Results: Single oral administration of ARG A reduced blood glucose levels from 26.50±0.61 mmol/L to 14.27±0.73 mmol/L (p<0.0001) six hours after administration in STZ diabetic rats. Furthermore, blood glucose levels were decreased from 5.35±0.30 mmol/L to 3.57±0.17 mmol/L (p<0.0001) and from 26.50±0.61 mmol/L to 3.67±0.29 mmol/L (p<0.0001) in normal and STZ diabetic rats, respectively, after seven days of treatment. Moreover, no significant changes in body weight in normal and STZ rats were shown. According to the lipid profile, the plasma triglycerides levels were decreased significantly in diabetic rats after seven days of ARG treatment (p<0.05). Moreover, seven days of ARG A treatment decreased significantly the plasma cholesterol concentrations (p<0.001). Conclusion: ARG A possesses glucose and lipid-lowering activity in diabetic rats and this natural compound may be beneficial in the treatment of diabetes.

Objective: The concept of the synergistic effect of poly-herbalism was as old as medicine history. Present novel polyherbal formulation (PHF) composed of five different herbs. The present investigation aimed to evaluate the synergistic therapeutic hypoglycemic potential of PHF against streptozotocin (STZ) (60 mg/kg b.w, ip)-induced diabetic rats. Methods: For this therapeutic study, the dose was framed orally once a day to the test objects after STZ dosing at 500 mg/kg/5 ml dosage levels for 21 days. The transformation of body weight and blood glucose level was examined, and the histopathological changes of beta cells of the pancreas, cellular architectures of liver and kidney were also perceived after scarification of the objects. Results: The outcomes were compared to that of glibenclamide (5 mg/kg) treated group. Declines of body weight and blood glucose levels were perceived in STZ-induced diabetic animals very significantly (p<0.01 or p<0.05). However, these diabetic changes were significantly (p<0.01 or p<0.05) decreased in PHF-dosing groups revealed more encouraging effects compared to that of glibenclamide. In the other hand, various liver function and enzymes test (creatinine, urea, total bilirubin, total albumin, alkaline phosphatase, gamma-glutamyl transferase, aspartate transaminases, and alanine transaminases) and lipid profile (total cholesterol, triglycerides, high-density lipoprotein cholesterol, total protein, low-density lipoprotein [LDL], and very LDL) studies strongly indicate the potential action of this novel formulation. Conclusions: It is deliberated that PHF has the favorable effect to normalize the blood glucose levels, and also rejuvenation and reproduction of beta cells lead a better futuristic ant diabetic therapy for diabetic management.

Introduction: Argania Spinosa L. (Sapotaceae) is an endemic species from south-western Morocco. This plant has many traditional uses including its use in the treatment of diabetes. Objective: The objective of the study was to evaluate the antidiabetic activity of Argania Spinosa Leaf Aqueous Extract (A.S.L.A.E). Methods: The antidiabetic effect of A.S.L.A.E was evaluated in both normal and streptozotocin (STZ)-induced diabetic rats treated at a dose of 20 mg/kg body weight for 15 days. The histopathological changes in the liver were evaluated. In addition, the antioxidant activity of this extract was also studied. Results: Single oral administration of A.S.L.A.E (20 mg/kg) showed no significant change in blood glucose levels in both normal and STZ induced diabetic rats after 6 hours of administration. Furthermore, in normal rats, repeated oral administration of A.S.L.A.E reduced blood glucose levels. Moreover, blood glucose levels decreased in STZ diabetic rats after fifteen days of treatment. According to the oral glucose tolerance test, the A.S.L.A.E (20 mg/kg) was shown to prevent significantly the increase in blood glucose levels in normal treated rats. Moreover, A.S.L.A.E showed antioxidant activity. Conclusion: The results show that Argania spinosa leaf aqueous extract possesses significant antihyperglycemic activity.

Gynura divaricata (GD) also known as Dewa leaf is one of the Indonesian medicinal plants which are also native to India, Thailand and China. GD is widely used as antidiabetic, antihypertensive and other diseases including several tumors. However, research on the effects of GD as antidiabetic is still not widely practiced, especially in Indonesia. The aim of this research is to investigate the effect of GD ethanolic extract on blood glucose levels of alloxan-induced diabetes mice. This research is an experimental research with pre- and post-test design using 24 male DDY strain mice. Animals experiment is divided into four groups, that are one normal group and three alloxan-induced diabetes mice group that give 1% CMC (control), 400[Formula: see text]mg/kg GD ethanolic extract and 0.65[Formula: see text]mg/kg glibenclamide, respectively. Treatment was given for 14 days. Blood glucose levels were measured before and after inducing alloxan, and after 14 days treatment. At the end of study, all of animals experiment were sacrificed for histological examination. Phytochemical analysis revealed that polyphenols, flavonoids, steroids, triterpenoids, terpenoids and and quinones were present in ethanol extract of GD. The results of this study showed significant ([Formula: see text]) decrease of blood glucose levels after GD ethanolic extract and glibenclamide treatment. The results of histological examination showed improvement in pancreas damage and significant increase in the number of beta cells in GD and glibenclamide groups. The results indicate that dewa leaf ethanolic extract has antidiabetic activity and the effectiveness is the same as glibenclamide. GD also could repair damage of pancreas caused by alloxan induction.
