  • Pterostilbene: A highly reliable quality-control marker for the Ayurvedic antidiabetic plant 'Bijasar' 
    Mallavadhani, U.V.; Sahu, G. (Chromatographia, 58(5-6), 2003: 307-312)
    In the Indian Ayurvedic system of medicine the heart wood of Bijasar (Lat: Pterocarpus marsupium; Fam: Leguminoceae) has been extensively used to treat diabetes mellitus. Detailed chemical and HPTLC analysis has been ...
  • Preferential extraction of gallium from Bayer liquor using ion exchange chelating resin containing hydroxamic acid functional group 
    Rao, K.S.; Sarangi, D.; Dash, P.K.; Chaudhury, G.R. (Journal Of Chemical Technology And Biotechnology, 78(5), 2003: 555-561)
    Gallium extraction studies were carried out using resin containing an hydroxamic acid functional group. Extraction was dependant on reaction time and alkali concentration. The resin did not extract aluminium. Vanadium ...
  • Wet chemical synthesis of low bulk density aluminium hydroxide powder 
    Pradhan, J.K.; Gochhayat, P.K.; Bhattacharya, I.N.; Das, S.C.; Panda, R.K. (Journal Of Chemical Technology And Biotechnology, 78(5), 2003: 577-581)
    Fine, low bulk density aluminium hydroxide powdered gel was prepared by the mild base hydrolysis of an aqueous solution of aluminium sulfate with hydrazine hydrate. Parameters such as method of addition of reactant, initial ...
  • Extraction and composition of the essential oil of ambrette (Abelmoschus moschtus) seeds 
    Rout, P.K.; Rao, Y.R.; Jena, K.S.; Sahoo, D.; Mishra, B.C. (Journal Of Essential Oil Research, 16(1), 2004: 35-37)
    Selective extraction with methanol of uncrushed ambrette seeds grown in India and liquid-liquid extraction of the residue afforded a volatile concentrate in 0.33% yield free from the fatty acids and off-notes associated ...
  • Essential oils of leaves of Curcuma species 
    Behura, S.; Srivastava, V.K. (Journal Of Essential Oil Research, 16(2), 2004: 109-110)
    The leaf oils of Curcuma caesia Roxb. and two cultivars of C. longa L. were investigated by GC. The leaf oils can be characterized by the following major constituents C. longa 'Roma': terpinolene (87.8%); C. longa 'Kasturi': ...
  • Sorption of arsenate from aqueous solution with manganic ferric oxyhydroxide 
    Chaudhury, G.R.; Chattopadhyay, P.; Das, R.P.; Muir, D.M.; Singh, P. (Hydrometallurgy 2003 Proceedings, Vols 1 And 2: Vol 1: Learning And Solution Purification - Vol 2: Electrometallurgy And Environmental Hydrometallurgy, 2003: 1913-1922)
    Adsorption techniques are comparatively low cost and effective for treatment of arsenic contaminated drinking water. Various adsorbents such as alumina, ferrihydrite and manganese ores have been used, but there has been ...
