Background: The leaves of Annona reticulata Linn. have been traditionally used by the tribes of Assam as a source of medicine to mitigate a range of health ailments including diabetes and obesity. Objectives: The current study aimed to evaluate the anti-diabetic and anti-hyperlipidemic potential of bioactive fractions isolated from the methanolic extract of Annona reticulata Linn. leaves using Nicotinamide + Streptozotocin (60 mg/kg, i.p.) induced diabetic rats. Methods: The partially purified bioactive fractions, namely F1, F2, F3 and F4 were administered to diabetic rats with the dose of 200 mg/kg, per oral (p.o.) and the effect of the fractions on serum glucose were studied up to 21 days. The potent fractions were further subjected for spectral analysis for identification of the isolated active compounds. Results: The in-vivo anti-diabetic activity of the isolated fractions F2 and F3 were found significant controlling blood glucose level, alike glibenclamide. Interestingly, F2 and F3 treated animals were found significant in restoring the lipid and liver enzymes profile in streptozotocin challenge rats. Further, spectral analysis revealed that F2 and F3 were comprises Quercetin and Gallic acid, respectively. Conclusion: Outcome of finding demonstrate the anti-diabetic and anti-hyperlipidemic potential of the isolates/fractions of A. reticulata, which were found enriched in polyphenolics including Quercetin and Gallic acid; and provides logistic behind the traditional use of the A. reticulata against Diabetes and obesity.

Phenolic Composition

The genus Cephalaria, belonging to the Caprifoliaceae family, is a rich source of interesting secondary metabolites, including mainly saponins which display a variety of biological activities, such as immunomodulatory, antimicrobial and hemolytic effects. Besides these compounds, flavonoids and phenolic acids were identified in Cephalaria species. Cephalaria is employed in traditional medicine e.g., to cure cardiac and lung diseases, rheumatism, and regulate menstruation. In this review we focus on the phenolic compound composition and antioxidative activity of Cephalaria species. The antioxidant effect can be explained by flavonoids present in all parts of these plants. However, future efforts should concentrate more on in vitro and in vivo studies and also on clinical trials in order to confirm the possibility of using these plants as natural antioxidants for the pharmacology, food or cosmetic industries.

Sequoyitol decreases blood glucose, improves glucose intolerance, and enhances insulin signaling in ob/ob mice. The aim of this study was to investigate the effects of sequoyitol on diabetic nephropathy in rats with type 2 diabetes mellitus and the mechanism of action. Diabetic rats, induced with a high-fat diet and a low dose of streptozotocin, and were administered sequoyitol (12.5, 25.0, and 50.0 mg·(kg body mass)−1·d−1) for 6 weeks. The levels of fasting blood glucose (FBG), serum insulin, blood urea nitrogen (BUN), and serum creatinine (SCr) were measured. The expression levels of p22phox, p47phox, NF-κB, and TGF-β1 were measured using immunohistochemisty, real-time PCR, and (or) Western blot. The total antioxidative capacity (T-AOC), as well as the levels of malondialdehyde (MDA) and reactive oxygen species (ROS) were also determined. The results showed that sequoyitol significantly decreased FBG, BUN, and SCr levels, and increased the insulin levels in diabetic rats. The level of T-AOC was significantly increased, while ROS and MDA levels and the expression of p22phox, p47phox, NF-κB, and TGF-β1 were decreased with sequoyitol treatment both in vivo and in vitro. These results suggested that sequoyitol ameliorates the progression of diabetic nephropathy in rats, as induced by a high-fat diet and a low dose of streptozotocin, through its glucose-lowering effects, antioxidant activity, and regulation of TGF-β1 expression.
