Total Phenolic Content of Three Samples from the Powdered Stem Bark of Detarium Microcarpum Guill. and Perr. (Fabaceae) by Abubakar Sani in BJSTR
Abstract
Preliminary processing of the plant material was done. The stem
cuttings were debarked and the barks dried in an open air under shade.
The macroscopical examinations were done. The dried plant materials were
powdered. Three different samples of the plant extracts/fraction
were used in the determination and the UV-Visible Spectrophotometric
Analysis method was adopted. Tannic acid was used as the standard.
The absorbencies were measured using the Jenway 630 UV-visible
spectrophotometer at 570nm against water: methanol blank. The various
absorbance obtained were plotted against the corresponding
concentrations to obtain a standard calibration curve.
