The present research work used G.
mangostana fruit for the biosynthesis of
silver nanoparticles and studied their effect
on microbial growth. The fruits of G.
mangostana was dried and ground to fine
powder before subjecting to crude
phytochemical extraction. As the G.
mangostana extract was mixed with aqueous
solution of 1mM silver nitrate it started to
change colour to reddish brown due to
reduction of silver ions; which indicates the
formation of silver nanoparticles which is
represented in (Figure 1A & B). The color
turned to reddish brown and this change has
been observed in several investigations
