Eleven compounds have been isolated for the first time from Daphne mucronata namely, cinnamic acid (1), 7,8-dimethoxycoumarin (2), 7,8-dihydroxycoumarin (3), lupeol (4), ßamyrin (5), betulin (6), 5,6,7,8,3',4'-hexamethoxyflavone ...

Urea and its N-alkyl/aryl derivatives react with o-phthalaldehyde (OPTA) to yield blue to purple coloration along-with isoindoline compounds (VII a,b,c) in acidic media. The color is unstable and changes into various shades ...

The effects of plant growth regulators, viz. Indole acetic acid (IAA), Gibberellic acid (GA) and Abscisic acid (ABA) were studied on fatty acid compositions, glucosinolate content and protein content of Brassica campestris ...

Nigella sativa (L.) a member of family Ranunculaceae is an annual herbaceous plant indigenous to the Mediterranean region contains more than 100 nutrients and had been used for edible and medicinal purposes in major parts ...

The regularity immobilization of medical mixture of compounds —alchidine over the composite carrier on the basis of bentonite clay and physical polymer gels have been studied by the methods of sorption and desorption. It ...

An isoenzyme of high molecular weight acid phosphatase (HM-ACP) from the liver of fish Rohu (Labeo Rohita) was isolated and purified to homogeneity. The enzyme had specific activity of 14.96 U/mg and a recovery of about 4 ...

During the last two decades, the high rate of industrialization, unplanned urbanization and heavy load of transportation resulted in a drastic increase in water pollution within the Peshawar basin in general and in the ...

Four electrodes with liquid membrane, Cu2+-selective and Ni2+-selective, not previously described in the literature, were prepared and characterized. Electrodes I and 2 are based on mixed complexes of Cu(ll) and Ni(ll) ...

Density and viscosity measurements, over a wide range of concentration and temperature, were implied to investigate the effect of hydrophilic block length on the micellar properties of the aqueous solution of E40B8, EgoB8 ...

The adsorption of CO at room temperature on finely divided ZnO surfaces, studied by FTIR, shows reversible bands (2250-2050 cm-I) and irreversible absorption bands (1800-600 cm-I ). The irreversible absorption bands (1800-600 ...
