High-performance liquid chromatographic (HPLC) and subcritical fluid chromatographic (SFC) separations of the enantiomers of structurally diverse, basic ß-carboline, tetrahydroisoquinoline and benzazepine analogues of pharmacological interest were performed applying chiral stationary phases (CSPs) based on (i) neutral polysaccharides- and (ii) zwitterionic sulfonic acid derivatives of Cinchona alkaloids.

Waxes are esters of long-chain fatty acids with long-chain fatty alcohols found abundant in the environment in various forms. Bacteria degrading these waxes in agricultural residues, soils and insects are gaining increased attention. In India, about 500 million tonnes of crop residues are generated annually and these crop residues are rich in cellulose, hemicellulose, lignin, pectin, cutin, waxes, fats and oils. Accumulation of waxy rich crop residues in the environment decreases the rate of decomposition and increase the hydrophobicity of soils.
