Intact Lipid

Trigalactosyl diglyceride has been isolated from tubers of potato (Solanum tuberosum) by a combination of chromatographic methods. This galactolipid, which constitutes approximately 1% by weight of the total lipids, was characterized by analysis of the intact lipid and its deacylation product. The fatty acids:glycerol:galactose molar proportions were shown to be close to 2:1:3. Evidence was obtained that suggests that trigalactosyl diglyceride is a higher homologue of mono- and di-galactosyl diglycerides and contains an additional d-galactopyranosyl moiety that is linked α-(1→6) to the terminal galactose unit of digalactosyl diglyceride.

Important Disease

Potato (Solanum tuberosum L.) has various biotic constraints in its production due to pest attack. Among these, common scab caused by streptomyces scabies is an important disease in potato which causes economic loss with respect to plant yield and quality of tubers. The present study was conducted to determine the pathogenicity, pathogenic variation, characterization of morphological, physiological and biochemical aspects of Streptomyces associated with potato tubers grown in Rawalpindi district. Severity data and pathogenic variation of disease was studied by using different isolation and characterization techniques.

Piperazine Derivative

: Levocetirizine is the active R-enantiomer of the racemate cetirizine, the latter being a piperazine derivative and human metabolite of the first-generation antihistamine hydroxyzine. In this study, a pharmaceutical impurity was detected and isolated through various chromatographic methods. The structure was identified as levocetirizine quaternary ammonium by mass spectrometry and NMR spectroscopy. The formation mechanisms of the impurity were also presented.
