Figure 5 shows the FT-IR spectra of the gel and powder form of extracted saponin. The IR
spectra shows important absorption bands at 3354 cm-1(attributed to OH stretching) , 2935
cm -1 (assigned to C−C overtone) and 1633-1662 cm -1 (assigned to C=C stretching).Those
peaks clearly shows that saponin have been extracted from ginseng.
