Opis:: Present investigation deals with the preliminary phytochemical analysis of Barleria longiflora. The leaf, stem and root of this plant were subjected to successive soxhlet extraction using petroleum ether, chloroform and ethanol. The various part of extracts, were subjected to preliminary phytochemical screening for different classes of phytoconstituents. Phytochemical analysis, ethanol extracts showed presence of all compounds.

Opis:: Some new chalcones are synthesized by the condensation of aryl ketones with aromatic aldehydes and solubility of these synthesized chalcones is determined in chloroform and dichloromethane at temperatures ranging between 293.15 K and 313.15 K by gravimetric method. The experimental data was correlated well with modified Apelblat equation. Further, from the experimental solubility data, some thermodynamic parameters such as dissolution enthalpy, Gibb’s energy and entropy etc. were evaluated using van’t Hoff equation. The positive Gibb’s energy and negative entropy suggests spontaneous dissolution and more ordered structure in solution.
