Abstract:
In recent years, nanotechnology is developing very quickly and gaining more attention. In the
field of green nanotechnology, there is a synthesis of nanoparticles using environment-friendly
approach which is cost efficient and lesser time required. These properties are shown by plant
extract and hence they are used for the synthesis of nanoparticles. Plant extract consists of various
phytochemicals like alkaloids, terpenoids, flavones, ketones, aldehydes, amides, and carboxylic
acids. These particles are associated in the synthesis of silver nanoparticles as it will serve as
reducing and capping agents for the conversion of silver nitrate to silver nanoparticles. The
enormous potential has been shown by the medicinal plants in the evolution of the new drug
molecules for different types of severe diseases. Nowadays latest medicines are present in the
market but herbal medicines still conserve the popularity for historical and cultural reasons [67].
The great potential of medicinal plant is used for various types of experiment observation, and
one of the traditional medicinal plant is Piper longum. Piper longum Linn (Indian long pepper)
is one of the common culinary herb and has been extensively used as an important constituent of
various indigenous medicines, specifically in traditional Indian medicinal system known as
Ayurveda. The main objective of the current work is to synthesize silver nanoparticles in an
aqueous medium using a simple, rapid and inexpensive synthetic approach based on green
synthesis technique. The effect of 1mM silver nitrate (AgNO3) solution on Piper longum aqueous
extract and synthesis of nanoparticles. The reaction mixture turned brownish colored after 3 hours
of incubation period, the synthesized nanoparticles were confirmed using UV-Visible
Spectrophotometer. The main objective of this paper is to synthesize silver nanoparticles from
aqueous leaf extract of Piper longum.
