Abstract
In the present research project, Phoenix dactylifera mucilage was explored to disclose its modification and capping potential
for encapsulation of silver nano particles. Process of silver nano formulation was monitored by running the sample on UV/
VIS spectrophotometry. Antioxidant, antimicrobial activity as well as cytotoxicity of crude and modified mucilage were
analyzed. Synthesized spherical nanoparticles were sized up to 39 nm. UV/ VIS spectrophotometric results revealed an
intense peak at 427 nm along with other small peaks in region of 350-450 nm owing to the existence of poly disperse silver
nanoparticles. Maximum phenolic contents were displayed by crude mucilage (230.37 ± 0.04 mg GAE/100g dw).
Scavenging activity (44.18 ± 0.95%) and flavonoid contents (28.47 ± 0.07 mg QE/100g dw) were detected maximum in
carboxymethylated mucilage. Nano formulated mucilage exhibited bactericidal activity maximum against Escherichia coli
and minimum against Staphylococcus aureus and inhibition zone was calculated up to 35 and 17 mm respectively. Growth
inhibition of Fusarium solani and Aspergillus niger by nano formulated mucilage was maximum (45.00 & 66.67%,
respectively) of all the samples under investigations. The outcome exposed that such modified products might have potential
applications in food as well as medicinal products.
