%X The
antioxidant of seeds was carried out using extracts from methanol and Silver
Nanoparticles from the spice. The SEM shows the shapes, dispersion and
agglomeration of the sample, while the EDX confirms the SEM and the presence of
some compounds. The FT-IR reveal</span><span style=\"font-family:&quot;\">s</span><span style=\"font-family:&quot;\"> the AgNP<sub>s</sub> capping and reducing the particular biomolecule
from the functional group for identification. Compounds found in the FT-IR seeds
of <i>Capsicum annum </i>are </span><span style=\"font-family:&quot;\">Ag L (Silver iodide), C K
(Cyanogen chloride), P K (Phenol). </span><a name=\"_Hlk105563159\"></a><i><span style=\"font-family:&quot;\">Monodora myristica </span></i><span></span><span style=\"font-family:&quot;\">are </span><span style=\"font-family:&quot;\">Mo L (Molybdenum), Ag L
(Silver iodide), C K (Cyanogen chloride), P K (Phenol), Mg K (Magnesium). </span><i><span style=\"font-family:&quot;\">Piper guineense </span></i><span style=\"font-family:&quot;\">are </span><span style=\"font-family:&quot;\">Ag L (Silver iodide), Ci K
(Potassium chloride), C K (Cyanogen chloride), P K (Phenol).</span><i><span style=\"font-family:&quot;\"> </span></i><span style=\"font-family:&quot;\">The seeds show that the AgNP<sub>S</sub> of CA and MM has a better antioxidant activity than the methanol of CA and MM,
while the PG methanol has a better activity than the AgNP<sub>S</sub> PG. The
control (Catechin and Galic acid) has a slight overall better DPPH activity
than the AgNP<sub>S</sub>. It is important to note that there is a
concentration dependency in CA, MM AgNP<sub>S,</sub> PG methanol respectively.
Notably, at CA methanol, the conc. at 125 was higher than the conc. at 250.
Hence, </span><span style=\"font-family:&quot;\">there is need to create a great part in using plant
samples for making tabulated or capsulated drugs for treatment of diseases and
using plant silver nanoparticles to develop a healthy food/drug preservative
package material </span><span style=\"font-family:&quot;\">¡°</span><span style=\"font-family:&quot;\">smart
packaging</span><span style=\"font-family:&quot;\">¡±</span><span style=\"font-family:&quot;\"> that
will enhance shelf-life.
