The
optical density value at this wavelength
gave the maximum value of optical
density, while the wavelength at visible
region gave the value of optical density
very low and unstable. The optical
densities of aqueous extracts are given in
Table 1. The results in Table 1 show that
the optical density increased with an
increase in the quantity of Mangosteen
Rind and reached the maximum with 10 g
of Mangosteen Rind powder for 100 ml.
of tap water. The optical densities were
not significantly increased with an
increase in the quantity of Mangosteen
Rind powder. Therefore, 2 g of Mangosteen
Rind powder was used for aqueous
extracts through out this study.
