Solid State Characterization of Ceftiofur Sodium Polymorph

ABSTRACT:
The present study deals with the solid state characterization of novel Ceftiofur Sodium having moisture content in the range of 5.0-8.0%. Here the analytical challenge is to determine the exact hydration state, i.e. Dihydrate or Hemipentahydrate or Trihydrate. Based on the results of vacuum assisted PXRD, DSC, TGA, DVS and HSM the hydration state was confirmed as trihydrate wherein one mole in the lattice, forms channel hydrate and two moles are possibly present as ion-associated.

Evaluation of acrylate-sunflower oil copolymer as viscosity index improvers for lube oils

Image
ABSTRACT: Copolymers of sunflower oil with methyl methacrylate and decyl acrylate were synthesized and characterized. Intrinsic viscosity and viscometric molecular weight were determined by using Huggins and Mark- Houwink equation respectively. Viscosity index (VI) of the additive doped base oils were evaluated and compared with that of the mineral base oils. VI values of the additive doped base oils depend on the nature of mineral base oils used and the type and concentration of VI improvers. For a comparison, respective homopolymers e.g. polymer of sunflower oil, poly(methyl methacrylate) and poly(decyl acrylate) were also prepared, characterized and evaluated in the similar fashion.

Hepatoprotective and antioxidant efficacy of Anethum graveolens linn in carbon tetrachloride induced hepatotoxicity in albino rats

Image
ABSTRACT: In the present study, the hepatoprotective and antioxidant efficacy of Anethum graveolens Linn was evaluated in CCl4 induced hepatotoxicity in albino rats. Hepatotoxicity was induced in albino rats by subcutaneous injection of carbon tetrachloride. Hepatoprotective efficiency of 100 mg/Kg wt of ethonalic extract of Anethum graveolens Linn was evaluated. Hepatotoxicity in experimental rats was evidenced by enhancement in the activity of SGOT, SGPT, MDA, & ALP and significant decrease in the activity of GSH, GPX, SOD & CAT. In plant extract treated animals, the toxicity effect of CCl4 was controlled significantly by restoration of the activity of above serum enzymes and antioxidant enzymes compared to the normal and standard drug silymarin treated groups. Therefore the results of present study support the hepatoprotective effect of Anethum graveolens Linn.
