Dried seeds of Cassia auriculata, C.absus and C.fistula were collected from the forest of Javaathu hills, Tiruvannamalai District, Tamil Nadu, India for the comparative analysis of antimicrobial activity and phyto-chemical potential. The active bio-compounds from the seeds of above plants were extracted with ethyl acetate, hexane and methanol and found methanol as a suitable solvent, hence used for further analysis. The phytochemical screening of the seeds showed the presence of alkaloids, phenolics and flavanoids in all species; glycosides in C.absus; reducing sugars in C.auriculata and C.fistula; non-reducing sugars in C.absus and C.fistula and Saponins in C.absus and C.auriculata from trace to higher amounts. The quantitative determination of phenol and flavanoids of methanolic seed extracts from C. auriculata, C.absus and C. fistula revealed total phenolic content as 0.18, 0.15, 0.11 and flavonoids 0.08, 0.092, 0.087% respectively. The antibacterial activity of methanolic seed extract was tested using agar well diffusion method and broth dilution method for the inhibitory effect. In the test for antimicrobial activity, methanol extracts show inhibition against almost all tested pathogens. C.absus showed higher zone of inhibition (ZOI) as 21 mm against Micrococcus luteus and as 17 cm against Klepsella pnuemoniae at 1000 μg concentration. But C.auriculata and C.fistula had moderate inhibitory effect on all the bacterial spceies from 500 μg to 1000 μg concentrations. The antifungal activity of C. absus, C.auriculata and C. fistula seed extracts were tested by agar well diffusion method and found to have inhibitory effect against all the tested fungi viz. Candida albicans, C.parapsilosis and C.tropicalis from 11 mm to 21 mm ZOI. Our study provides the scientific validation for their traditional use in medicinal applications.Keywords

Ultrasonic velocity (U), density (ρ) and viscosity (η) for the ternary liquid mixtures of benzaldehyde+tetrachloromethane+o-cresol, benzaldehyde+tetrachloromethane+m-cresol and benzaldehyde+tetrachloromethane+p-cresol have been measured as a function of the composition at 303, 308 and 313K. The experimental data have been used to calculate some excess acoustical parameters, such as adiabatic compressibility (βE), free length (LfE) and free volume (VfE). The results are discussed and interpretered in terms of specific interaction predominated by hydrogen bonding.Keywords

Apparent molal compressibilities (φK) and apparent molal volumes (φV), of L-serine, L-arginine and Lphenylalanine in aqueous sodium hydroxide solutions (0.0-0.10 mol kg–1) at 303.15 K have been determined from precise density and ultrasonic velocity measurements. Limiting apparent molal compressibilities (φKO), limiting apparent molal volumes (φVO) and their constants (SK,SV) of these amino acids at infinite dilution were evaluated. Transfer adiabatic compressibilities (ΔφKO) and transfer volumes (ΔφVO) at infinite dilution from water to aqueous sodium hydroxide solutions have been calculated. These derived parameters have been interpreted in terms of ion-solvent and ion-ion interactions in the studied solutions.Keywords

Ultrasonic velocity, density and attenuation measurements in V2O5-P2O5, V2O5-ZnO-P2O5 and V2O5-MnO-P2O5 composition glasses have been made at the room temperature by making use of pulse echo method. These values are utilised to evaluate elastic moduli such as longitudinal, Young's, bulk and shear, Poisson's ratio, acoustic impedance, micro hardness, internal friction, Debye temperature and thermal expansion coefficient. The structural and physical properties of the glass samples have been discussed in the light of the above parameters.Keywords
