The ethanol extract of Solanum surratense(EESS)(Family: Solanaceae) root was investigated for its anti-diabetic effect in Wistar Albino rats. Diabetes was induced in Albino rats by administration of single dose of Alloxan monohydrate (150mg/kg). The ethanol extract of Solanum surratense at the dose of 200mg/kg and 400mg/kg, p.o. was administered as single dose per day to diabetes induced rats for a period of 21 days. The effect of EESS root on body weight of the animals, blood glucose, serum lipid profile [cholesterol, triglycerides], serum enzymes[serum glutamate oxaloacetate transamines(SGOT), Serum glutamate pyruvate transaminases(SGPT), alkaline phosphatase(ALP)], total protein were measured in the diabetic rats. EESS root elicited significant (p< 0.01) reductions of blood glucose, lipid parameters and serum enzymes and significant (p<0.01) reductions of blood glucose. From the above result, it is concluded that EESS root possesses significant anti-diabetic effects in Alloxan induced diabetic rats....

Medicinal plants are a source of naturally active compounds used extensively by tribal people worldwide for many ailments. Withania somnifera (WS) is one such plant used to treat many ailments from the time of Ayurveda. Extraction of the bioactive plant constituents from the whole plant or from the different parts of the plant has always been a challenging task. As the dried roots of WSare widely used in the treatment of many disorders, the current investigation aimed at extraction and detection or screening of active phytochemical compounds from different extracts of WS root. Phytochemical screening of different extractions revealed the presence of phenols, flavonoids, tannins, saponins, alkaloids, steroids, terpenoids, glycosides and reducing sugars which could account for its varied medicinal properties like anti-inflammatory, anti-spasmodic, anti-analgesic, neuroprotective and diurectic...

Gum Dammar is a natural resinous material of plant Shorea javanica, family–Dipterocarpaceae. In the present investigation Dammar gum (DG) and alcohol soluble fraction of Dammar gum (DA) are evaluated for their physicochemical, mechanical and film forming characteristics. Films were produced by casting/solvent evaporation method from plasticizer free and plasticizer containing solutions. Films prepared from different formulations were studied for their mechanical (tensile strength, percent elongation and Young’s modulus), water vapor transmission and moisture absorption characteristics. Unplasticized DG, DA films were brittle and posed the problem of breaking during handling. Hydrophobic plasticizers, dibutyl phthalate (DBP), improved the mechanical properties of free films with plasticizer showing significant effects on film elongation. Thus present study proposes DG and DA as excellent film...

The homo and hetero interaction in the binary mixtures of Ethyl acetate + n-Butylamine, Ethyl acetate + Cyclohexylamine and Ethyl acetate + Diethylamine has been investigated through the orientation of dipoles using dielectric polarization method. The dielectric and thermodynamic parameters such as Kirkwood correlation factor, Excess permittivity, Bruggemann factor and Dipolar excess free energy for the above systems have been calculated from the experimentally measured values of capacitance and refractive index of solutions, at temperatures 303K, 313K and 323K.In all the studied systems, the dielectric parameters obtained show systematic change in the molecular structure with the concentration of amine in the solution. It indicates that the β-multimer formation due to the presence of hetero interaction between the components of above...

A study was undertaken to fractionate and characterize the antidiabetic potential of Cyperus pangorei rhizomes. The column chromatography and HPTLC study was performed on ethyl acetate fraction and five sub-fractions were separated and subjected for the evaluation of antidiabetic potential in streptozotocin induced diabetic rats. The experimental data indicated that the ethyl acetate sub-fractions SF4 (26.39%) (P < 0.05) and SF5 (43.69%) (P < 0.05) at the dose of 50mg/kg BW produced the maximum fall in the blood glucose level of diabetic rats after 15 days of treatment. Elevated levels of triglycerides (TG), total cholesterol (TC), low density lipoprotein (LDL), very low density lipoprotein (VLDL) and decrease level of high density lipoprotein (HDL) and serum insulin level were observed in Streptozotocin-induced diabetic rats. While significant differences were observed in serum insulin level and serum lipid profiles in sub fractions treated diabetic animals, when compared with the diabetic control and normal animals (P < 0.01). In sub fractions SF4 and SF5 treated group decreased level of serum TG, TC, LDL...
