    halogen group is targeted. Enzymes like oxygenases play a major role. The bonds like ester-‚ amide-‚ or ether bonds present in the compounds are first attacked leading to breaking down of compounds. In some cases the aliphatic chains and in aromatic compounds the aromatic components may be targeted. The site and mode of attack depends on the action of enzyme‚ its concentration and the favourable

    b-CD) cavity protons as well as roxatidine acetate hydrochloride aromatic ring protons revealed the formation of a RAH–b-CD inclusion complex. Detailed FTIR and NMR spectroscopic (1H NMR‚ COSY‚ NOESY‚ ROESY) studies have been done. The stoichiometry of the complex was determined to be 1:1‚ and the overall binding constant was also determined by Scott’s method. The NOESY spectrum confirmed the selective penetration of the aromatic ring of RAH into the b-CD cavity in comparison to that of the piperidine

    converted to the orange sodium salt known as the methyl orange. INTRODUCTION Para-nitrobenzeneazoresorcinol dye and methyl orange belong to a class of dyes known as “azo colors” which contain the azo group linked to two aromatic nuclei. The nature of the aromatic substituent’s on both sides of the azo group (-N=N-) controls the colors of the azo compound as well as the water- solubility of dyes and how well they bind to a particular fabric. In addition to the azo group‚ the dyes
