The bioactive peptides derived from food have increased consideration for their function in averting numerous chronic diseases, comprising, diabetes and obesity. Edible insects are the feasible composition of bioactive peptides owing to their high protein content and viable production. The present study was aimed to evaluate the antidiabetic and anti-obesity effects of seven edible insects’ protein hydrolysates after simulated gastrointestinal enzymatic digestion. Antidiabetic and anti-obesity efficiency was determined by the inhibition of digestive enzymes viz., dipeptidyl peptidase-IV, α-glucosidase, and α-lipase activity. Three active protein hydrolysate extracts (1.25, 2.5, and 5mg/dl) were selected and analyzed in terms of their IC50 values, and all tested extracts inhibited those enzyme activities in a dose-dependent manner. Based on the present study, we conclude the seven edible insects’ hydrolysate have potential enzyme inhibitory activities and thereby proved as an antidiabetic and anti-obesity...

Objective: We report the phyto-pharmacognostic evaluation and HPTLC finger-printing profile of the methanolic extract of Saptaparṇa [Alstonia scholaris (L.) R. Br.] leaves – unaffected and gall-affected, collected in January 2019. Materials and Methods: Physicochemical parameters and phytochemical screening were done by standard procedures. HPTLC finger-printing profile of the methanolic extracts of dried leaves and dried leaves with gall was performed on pre-coated TLC silica gel 60F254 plates with hexane: EtOAc: MeOH: formic acid (5:4.5:0.5:0.5 v/v) as developing solvent, with observation at 254 and 366 nm. Results: Some of the leaves had 15-20 galls on both surfaces. Powder Microscopy of the bitter-tasting green color leaf powder showed a group of epidermal cells, unicellular trichomes, elongated stone cells in the group, prismatic calcium oxalate crystals, single-layered fibers, reticulate vessels, anomocytic stomata, and reddish-brown color tannin matter; epidermis of gall cells, insect body in affected leaves. Phytochemical screening revealed the presence of alkaloids, carbohydrates, terpenoids/steroids, phenolic compounds/ tannins, but an absence of reducing sugars and flavonoids. A large number of bands were...

Diabetes Mellitus is the most common endocrine disorder, affecting a larger population of the world, which arises due to defective insulin secretion by beta cells in the pancreas or insulin resistance by peripheral tissues. As the disease progress, microvascular complications like nephropathy, neuropathy, retinopathy, and cardiovascular complications are observed, which the leading causes of death in diabetic patients. The drug treatment is required when the weight reduction, diet, and modification in lifestyle fails to maintain the normal blood glucose level. Though insulin and oral anti-diabetic drugs are clinically being used; the researchers have been focused on developing still better anti-diabetic drugs. There components like GLP-1, DPP-4, GPR119, GPR 40 and GPR 120, SGLT2, DGAT-1, 11 β-hydroxysteroid dehydrogenase, and Peroxisome proliferator influences/regulate the secretion, release, and uptake of insulin. The study of these targets would help to develop new anti diabetic...

The purpose of current research work has been made to formulate a gastro-retentive drug delivery system (GRDDS) of those drugs having a narrow absorption window or having good absorption at the proximal part of the gastrointestinal tract (GIT) to deliver at stomach site and to improve the bioavailability of a drug. Gastro-retentive hydrogel tablet of Cefixime trihydrate was prepared by the direct compression method via using carbopol 940 and chitosan with different concentrations. Cefixime is a very poorly water-soluble drug after its oral administration so that it is slowly and incompletely absorbed from the gastrointestinal tract, which results within poor bioavailability i.e., 40-50%. Hydrogel was characterized concerning diverse parameters with mechanical strength, swelling ratio, in-vitro drug release, etc. The drug release from a combination of carbopol 940 and chitosan-based hydrogel showed for a prolonged period. A 32 full factorial design was utilized to optimize the tablet of cefixime trihydrate by selecting an amount of carbopol 940 and chitosan as independent variables and effects were observed on drug release and...

Quality by Design (QbD) is a systematic approach for the development of products and processes. Azilsartan Medoxomil is a competitive antagonist of the Angiotensin II Type 1 receptor. A precise and reproducible ultra-performance liquid chromatographic (UPLC) method was developed and validated for the estimation of Azilsartan Medoxomil from its marketed tablet dosage form applying Quality by Design approach. Eight experiments were conducted using the full factorial design in order to rationally examine the effects of stationary phase, buffer pH and organic phase concentration in primary screening followed by method optimization with variation in Column temperature and flow rate. Chromatographic separation of AZIL was achieved at 40 °C temperature using an Acquity UPLC BEH C18 (4.6mm × 2.1mm, 1.7μ) analytical column; the mobile phase consisted of Acetonitrile: phosphate buffer (pH 5.5, 0.02mM) (40:60, v/v) at a flow rate of 0.3 ml min-1. Azilsartan eluted with retention time (Rt value) 2.41 min. The linear regression analysis showed good linear relationship with a correlation coefficient of 0.999. The limit of detection and...
