  The study was conducted to investigate the elemental constitutes in two varieties of indigenous medicinal plant Catharanthus roseus Vern Sada Bhar misapplied name was Vinca rosea. All parts of both varieties i.e. V. rosea with pink flower and other with white flower were analysed for elements, Ca, Na, K, Mg, Zn, Fe, Cu, Co, Mn, Ni, Cr, Cd, Pb, Ba and Al, by wet digestion method and available elements in decoction of each part of both varieties, using atomic absorption spectrophotometer. The level of essential elements such as Zn, Fe, Mn, and Cu is present in considerable amount. The level of available Zn was observed in decoction of flower as compared to other parts of plant. High level of Fe was observed in pink flower variety of V. rosea. The level of Al was high in flower of V. rosea white variety as compared to flower of V. rosea pink variety. In decoction the level of essential elements is high as compared to toxic elements.

  A new method has been developed by preparing complexes involving condensation of amino acids with 8-hydroxyquinaldine using various experimental conditions. The products so obtained are being investigated for identification and quantitative analysis using different spectroscopic techniques including fluorescence activity of newly synthesized products. In present studies the identification of amino acids in nano mole quantities has become possible by fluorometric activity of amino acids-quinaldine complex involving different excitation and emission wavelengths. This fluorometric activity of complexes is 10 to 100 times more sensitive method than assay method involving ninhydrin. 2- methy1-8-hydroxyquinoline (8-hydroxyquinaldine) condensed with Alanine and Phenylalanine produced fluorescent complexes. The complexes separately have been investigated for identification and quantitative estimation of amino acids. The use of 8-hydroxyquinaldine for various purposes and its comparison to 8-hydroxyquinoline for similar purpose indicates decrease in fluorescence signal of 8-hydroxyquinaldine- amino acid complexes.

  A new method has been developed by preparing complexes involving condensation of amino acids with 8-hydroxyquinoline and 8-hydroxyquinaldine. The products so obtained are being investigated for identification and quantitative estimation of amino acids using different spectroscopic techniques including fluorescence activity of newly synthesized products. The method adopted in our laboratories is rapid, versatile, reproducible and provides excellent results for adoption by analytical, agricultural and biomedical laboratories to estimate amino acids and metals in composite matrix at economical costs. 8-hydroxyquinoline (Oxine) and 2-methyl-8-hydroxyquinoline (8-hydroxyquinaldine) condensed with valine produced fluorescent complexes. The complexes have been investigated for identification and quantitative estimation of amino acids. By this method identification of amino acids in nano mole quantities has become possible by fluorescence activity of valine-8-hydroxyquinoline and valine-8-hydroxyquinaldine complexes involving different excitation and emission wave lengths. This fluorescence activity of complexes is 100 to 1000 times higher than assay method involving ninhydrin and amino acid analyzer.

  The heavy metals or trace elements play vital role in the metabolic pathways during the growth and development of plants, when available in adequate concentration. Seasonal fruits and vegetables play a significant role in human nutrition. Food production and its safety is an important aspect of the measure of any nation’s growing economy and it is a popular trend to find out the trace metal contents of vegetables and fruits of local markets throughout the world but still data is lacking in developing countries like Pakistan. The trace metals Co, Zn, K, Na, Fe, Mn, Ca, Mg, Cu, Ni were analyzed in 15 vegetables and fruits (okra, guava, banana, potato, chili paper, onion, tomato, mint, mango, ginger, brinjal, bitter gourd, spinach, carrot) available in the markets of Hyderabad city. Vegetables and fruits selected for the study are commonly consumed by all income groups of Hyderabad city. Mineral contents were determined using Atomic Absorption Spectrometry (AAS). Co was analyzed 0.1038-0.126 mg/100 gm, Zn was 0.44-0.55 mg/100 gm, K 2.3-38.5 mg/100 gm, Na was 1.5-2. Mn was 0.0526-0.1435 mg/100 gm, Ca 0.3-3.35 mg/100 gm, Mg 1.191-32.0 mg/100 gm while Cu 0.1-1.9 mg/100 gm and Ni 0.05-0.18 mg/100 gm where as Fe was found 1.5-29.0 mg/100 gm among all selected vegetables and fruits.

  The use of sewage sludge on agricultural land provides an alternative for its disposal. Therefore, the aim of the present study was to evaluate the feasibility of using industrial sewage sludge produced in Pakistan, as an agricultural fertilizer. The agricultural soil amended with 250 g kg−1 sewage sludge with or without lime treatment was used for the growth of the common local grain crop, maize (Zea maize). The mobility of the trace and toxic metals in the sludge samples was assessed by applying a modified BCR sequential extraction procedure. The single extraction procedure was comprised of the application of a mild extractant (CaCl2) and water, for the estimation of the proportion of easily soluble metal fractions. To check the precision of the analytical results, the concentrations of trace and toxic metals in every step of the sequential extraction procedure were summed up and compared with total metal concentrations. The plant-available metal contents, as indicated by the deionized water and 0.01 mol L−1 CaCl2 solution extraction fractions and the exchangeable fraction of the sequential extraction, decreased significantly (P< 0.05) with lime application because of the reduced metal availability at a higher pH, except in the cases of Cd and Cu, whose mobility was slightly increased. Sludge amendment enhanced the dry weight yield of maize and the increase was more obvious for the soil with lime treatment. Liming the sewage sludge reduced the trace and toxic metal contents in the grain tissues, except Cu and Cd, which were below the permissible limits of these metals. The present experiment demonstrates that liming was an important factor in facilitating the growth of maize in sludge-amended soil.
