against multiple bacterial resistance isolates, including Gram-positive and negative
strains. The study showed that Murraya koenigii has shown antibacterial activity
(Panghal et al. 2011), another study used Curry leaves to investigate the antibacterial
effects; the leaves were powdered, and antimicrobial activity on Gram-positive and
Gram-negative bacteria was tested, the curry leaf extract showed inhibition zone
against bacteria culture.
3.4.1.4 Leaves Extracts and Bio-reduction
Plant extracts are mightily utilized in applications of the industry, and the possibility
to effect development of bioscience. Plant is the essential producer of the aqueous
system (Ingale and Chaudhari 2013), and its role in preventing the oxidation of metals and molecules from the environment often leads to the removal of toxicity in the
environment through degradation. It is said that bio-sources collect metals through
two steps, operation of biodiversity. This part is executed using functional groups
of vital compounds contained (Abdi and Kazemi 2015). In 2013, Bindhu and his
colleagues used the extract of Hibiscus cannabinus leaves with the concentration of
various metal ions and the reduction of ions and their conversion to neutral metal
nanoparticles at different reaction times (Bindhu and Umadevi 2013). A similar study
conducted by Ravichandran, et al. reported the synthesis of nanoparticles using plant
leaf extract to reduce Ag
+ ions to Ag nanoparticles from AgNO 3 solution during two
minutes of reaction time at room temperature (Ravichandran et al. 2016). Murraya
koenigii leaves extract is used for the synthesis of nanoparticles, and this synthesis is
attributed to the natural reduction agent, the carbazole may be present in the corresponding extracts (Kapoor and Singh 2010). Curry leaves have a potent antioxidant
due to the presence of high concentrations of carbazoles that is responsible for the
reducing and stabilizing of metal ions.
3.4.2 Green Synthesis of Metallic Nanoparticles
with Murraya Koenigii
Different methods have been used with plant extracts to synthesize metal nanoparticles. These methods have many features over physical, chemical, and microbial
syntheses because there is no need of the process of elaborated for maintaining and
culturing the cell, hazardous substances, and high-energy requirements (Awwad et al.
2013). The synthesis of metallic nanoparticles with plant leaves is further bio convenient comparing with other biological processes. It attracts much attention from
researchers to the extent that area of research on the utilize of plant leaf extracts in
nanoparticles produce called photosynthesis, become an eminent area of study in
nanotechnology (Ahmed and Ikram 2015). However, gold and silver nanoparticles
were synthesized rapidly using curry leaf extract (Philip et al. 2011). Curry leaves
