An Improved Method for the Determination of the Plasma Volume with Evans Blue

The extraction of Evans blue (T1824) from plasma and the measurement of plasma volume.

Haemolysis and lipaemia interfere with the direct photometric estimation of Evans blue in plasma. During an investigation of blood volume changes in surgical shock using this dye, lipaemia was often encountered and it was necessary to use an extraction procedure for the estimation of the dye concentration. A rapid method was desired. The method of Crooke and Morris (1942) using a hydrochloric a...

The estimation of Evans blue in plasma.

Chromatographic determination of Evans blue in plasma and serum.

The methods at present available for the determination of the dye, Evans blue, in plasma have certain disadvantages. Direct colorimetry of dyed plasma is inapplicable where the plasma is haemolyzed, turbid or lipaemic. The butanol extraction procedure of Harington, Pochin & Squire (1940) is troublesome and time-consuming where many analyses must be carried out; its accuracy is lower than those ...

An improved HPLC method for determination of colocynthin in colocynth

Background and objectives: Colocynthin is the major active secondary metabolite of colocynth, Citrullus colocynthis (L.) Schrad, which has been used in traditional and ethno medicine of many countries.  It could be considered as an active marker for quality control of colocynth and its herbal products. Analysis and standardization of colocynth and its herbal preparations are a critical...
