*3.5.1 Graphically presenting the data obtained from the reducing power assessment*

It has been identified that the reducing power assay of crystal compound was slightly discriminable with standard ascorbic acid at low concentration; however, the difference between plant material and standard has diminished with escalating concentration with giving high absorbance value as shown in **Figure 8**.
