Abstract :

PI indices for linear Phenylene are obtained by a significant method by considering its edges in various directions and their corresponding number of parallel edges in their molecular graph. In this paper, we obtained the PI index for linear Phenylene for various cases and different structures. The corresponding indices are derived as formulas and also the inferences are tabulated and the values are compared with its structures

Abstract :

The Complex reactions of some rare earths in the presence of Cetyltri methyl Ammonium Bromide (CTAB) and Triton X (TX-100) have been studied in detail. Precision and Accuracy data has been determined which has shown increase in both in the presence of surfactants. Dye – Surfactant complex i.e. modified reagent used as a ligand has shown a bathochromic effect which changes to hypso chromic shift in presence of metal ions. The composition of chelates of uranium with Eriochrome Cyanine R was found to be 1:1 in the absence of the surfactant and 1:2 in the presence of CTAB and TX. However, the composition of Y, with ECR was found to be 1:2, both in presence and absence of CTAB and TX. The studies on evaluation of stability constants as well as on various analytical parameters including effect of foreign ions proves the utility of ECR in the spectrophotometric micro determination of metal ions under study

Abstract :

Hedychium Spicatum (Kapoor Kacchri) is a vigorous tall growing ginger and consist multiple stem per pot. The underground part rhizome is useful in preparation of indigenous medicine. The crude extract of rhizome has been used in preparation of anticancerous drug. In addition to its medicinal values, the plant rhizome is reported to posses anti inflammatory, hypoglycaemic, vasodialator and hypotensive properties as well as antibacterial activity against both gram positive and gram negative bacteria. The major chemical constituents are limonene, cineole, terpinene, linalool, p-cymene, terpeneol and phellandrene.
