Abstract :

The purpose of present investigation is to analyse the Physico-Chemical parameters of ground water of different areas of Jaipur City during monsoon season 2016 and to compare with the standard results to make it suitable for drinking purposes. It has been noticed that pH value (7.4-8.00) is within the acceptable range14. The parameters viz. nitrate, sulphate, phosphate, chloride and fluoride usually determine the quality of ground water, are marginally high but are in acceptable range. However, it needs some degree of treatment before consumption. The alkanity and total hardness are marginally high but are within acceptable range (BIS 1991). The B.O.D. and C.O.D. are under standard limits in different parts of Jaipur city.

Abstract :

Antibacterial activity of plant Asparagus racemosus belonging to family LIliaceae ,was evaluated some selected human pathogenic microorganism (Pseudomonas aeroginosa,Escherichia coli, Staphylococcus aureus) following agar well diffusion method using different concentration (60%, 80%, 100%). Two solvents Methanol and Acetone were used for extraction. It was concluded from the results that Methanolic as well as Acetone root extract of Asparagus racemosus of were quite effective in inhibiting growth of staphylococcus aureus bacteria. Therefore, the root extract of this plant can be selected for further investigation to determine their therapeutic potential.

Abstract :

The anticancer drug Chlorambucil and its complex with Fe (II) have been qualitative and quantitative analyzed spectrometrically and electrochemically.
All the studies have been done in both phases i.e. solid and liquid. On the basis of elemental analysis, IR spectrometry, Polarography and Amperometric methods the probable formula of the complex has been worked out to be 1:2 (M: L).
Antimicrobial activity of complex has been determined using Disc diffusion method against various pathogenic bacteria and fungi. Obtained results is increased inhibition efficiency against the prepared complex, it is presumed that the complex may prove to be more potent as compared to Chlorambucil drug.
Pharmacological studies (In-Vitro and In-vivo) of prepared drug complex were done on sarcoma-180 tumor cell. The observed results revealed that the complex is more potent as compared to the pure drug in all above mentioned activities. As such Fe (II) Chlorambucil drug complex may be recommended to the therapeutic expert for its possible use as more potent anticancer drug.

Abstract :

A new, efficient Calcium ion selective electrode has been prepared using acyclic polyether based ionophore. The prepared ionophore is characterized by UV, FT-IR, XRD. Electrochemical impedance spectroscopy (EIS) technique is also employed to study the electrochemical & surfacereactions. The sensor exhibits a near Nernstian response for Ca(II) ion over a concentration range of 1.0 X 10-4M to1.0 M. The proposed sensors revealed relatively good selectivity and high sensitivity for Ca(II) over a mono and divalent cations. It can be used with in the pH range of 3.42 to 6.24 . The effect of medium and the selectivity coefficient values was evaluated using fixed interference method found to give a better response. The influence of temperature on electrode potential was studied & it can be used in the determination of thermodynamic functions like G, H & S. It was also successfully used in the analysis of concentration of Calcium ion in various real samples.

Abstract :

The rate of alkaline hydrolysis of ethyl nicotinate was measured over the temperature range of 20oC to 40 oC in water-ethanol mixture at different composition 30 to 70% (v/v). The influence of solvent variation on reaction rate was examined in term of changes in the Activation parameter .increase of H* and S* values with simultaneous increase in G* of the reaction in media, reveals that the reaction is Enthalpy controlled and Entropy domination.
The Values of Iso-kinetic which is equal to 360, clearly indicates that there is appreciable interaction between solvent and solute present in the reaction media, i.e. reaction is ion-dipole.

Abstract :

New Co(II) complexes with macrocyclic ligands 2, 7, 9, 14-tetrahydroxy phenyl-1, 3, 6, 8, 10, 13-hexaazacyclooctadecane (L1), 2, 7, 9, 14-tetracyclohexane-1, 3, 6, 8, 10, 13- hexaazacyclo octadecane(L2) have been synthesized by template method. The structure of complexes was determined by elemental analysis, molar conductance measurements, magnetic susceptibility measurements, IR and electronic spectral studies. Based on the analytical analysis i.e. molar conductance the complexes were found to be non-electrolytic in nature except the complexes [Co(L1,2)] (NO3)2] which is 1:2 electrolytic in nature. Thus, the complexes were found to have general compositions [Co(L)X2] and [Co(L)]X2 (where L = L1 and L2 ligands, X = Cl-, NO3 - CH3COO-). Magnetic moment and the electronic spectra of the complexes suggest that the ligands coordinate to metal ion via four donor sites to give six coordinate complexes having octahedral geometry except [Co(L1,2)] (NO3)2] which is four coordinated tetrahedral geometry. Food Poison Technique was employed for screening the in vitro antifungal studies of the complexes. The complexes were also examined for antifungal studies against pathogenic strains like Alternaria brassicae, Fusarium moniliformae, Rhizoctonia solani.
