ABSTRACT
In the present study, explains the detailed information about the synthesis of sliver
nanoparticles using the flower and stem of Costus igneus which was used to determine the
alpha amylase, alpha glucosidase inhibition assay and antioxidant activities are examined by
DPPH (diphenyl-2 picrylhydrozyl) method. The characterization of synthesized silver
nanoparticleswere confirmed by the UV-visible spectroscopy, Fourier transform infrared
spectroscopy (FTIR), X-ray diffraction (XRD), Scanning electron microscope (SEM), Energy
dispersive X-ray (EDX). The UV- visible spectroscopy was used to examine the silver
nanoparticles and the peak range was observed at 436nm. The FTIR was used to analyses the
functional group present in the plant extracts and silver nanoparticles. The SEM analysis
showed the cubic and spherical shape of the synthesized silver nanoparticles. The elemental
composition of the synthesized silver nanoparticles is determined by EDX analysis. The
crystalline nature of the silver nanoparticles was analyzed by using XRD technique. The result
shows that the flower-AgNPs exhibits inhibitory effect on alpha amylase (84.9%) and for the
stem-AgNPs (82.5%). alpha glucosidase showed inhibitory effects in comparison with flower-
AgNPs (58.3%) and stem-AgNPs (53.7%) by using standard acarbose drug. The antioxidant
activities by DPPH method exposed activity for flower-AgNPs (81.3%) and for the stem-
AgNPs (79.6%) were compared with standard ascorbic acid. The antiperiodontal analysis
showed a better inhibition against streptococcus mutans, streptococcus salivaryus, streptococcus sobrinus and staphylococcus aureus. Therefore, it is suggested that the
synthesized silver nanoparticles using flower and stem of Costus igneus extract as the good
yield of inhibitor for diabetes and periodontitis.
