Suitability of stem latex of jatropha gossypifolia as a protein precipitant for biochemical analysis.
The extract of Jatropha Gossypifolia stem was obtained by cutting the stem with a sharp knife and the fluid expressed out. The suitability of the stem latex extract as a precipitant for biochemical analysis was determined. The precipitating efficacy of the extract for creatinine and protein estimation was found to be optimum at 1/4 and 1/5 dilutions respectively aqueous solution. Plasma protein was precipitated with stem extract of J. Gossypifolia at the stated dilution. The mean plasma creatinine values obtained from 0.5 % sodium tungstate as a protein precipitant were compared with the values of plasma creatinine obtained when ¼ dilution of stem extract of J. Gossypifolia was used as protein precipitant. Similarly mean cerebrospinal fluid (CSF) and urinary protein values obtained from 3 % Tricholoro-acetic acid as protein precipitant were compared with values obtained from 1/5 dilution of stem extract of J. Gossypifolia as protein precipitant. The values obtained from the stem latex extract at the stated dilutions were comparable with values obtained from the conventional protein precipitants (p < 0.05). The stem latex extract of J. Gossypifolia is suitable as a protein precipitant for creatinine, CSF and urinary protein estimations. However further work need to be done to purify the extract and determine the exact concentration at the stated dilutions as well as the active ingredient in stem latex.
