Rapid method for determining ascorbic acid concentration

Rapid Stick Method for Determining Blood-glucose Concentration.

A High-performance Liquid Chromatography Method for Determining Ascorbic Acid Content of Fresh Fruits and Vegetables

Ascorbic acid of fresh fruits and vegetables was extracted with 6% metaphosphoric acid and determined effectively by using a Clg cartridge in a radial compression module and 1.5% NH4H2PO4 mobile phase in a high performance liquid chromatograph. The commonly used AOAC method (2) of First, fresh fruits and vegetables contain corndetermining ascorbic acid content in fresh pounds other than ascorbi...

Rapid method for determining serum bactericidal activity.

To screen large numbers of sera, a method was devised which utilizes the Steers-Foltz replicator which is usually used to determine minimal inhibitory concentration for antibiotics. Each of the wells (9 by 15 mm) of the replicator is filled with 0.06 ml of serum, 0.02 ml of a 10(5) suspension of organisms, and 0.02 ml of diluent (tris(hydroxymethyl)aminomethane-hydrochloride buffer, pH 8.4). Th...

Leucocyte ascorbic acid concentration and plasma ascorbic acid levels in children with various infections.

In this study leucocyte ascorbic acid concentrations and plasma ascorbic acid levels were measured simultaneously and correlation between these two variables was sought in various bacterial and viral infections. A total of 258 patients were studied. The control group consisted of 21 healthy children in the same age group. Except for scarlet fever no significant differences were observed between...
