“…Most of the Ag NP was roughly circular in shape with smooth edges. These structures were similar with those of the Ag nanoparticles produced from the extract prepared from leaves of Cinnamomum camphora and phyllanthin, which was attributed to a similarity in the reductive agents present in both plant species [49,50], such as tannins, phenols, saponins, and flavonoids [51,52]. No mortality was observed in the control.…”

“…These structures were identical with those of the Ag nanoparticles produced from the extract prepared from leaves of Cinnamomum camphora and phyllanthin, which was attributed to a similarity in the reductive agents present in both plant species [6,19]. The phytochemical constituents in the cannonball leaves such as tannins, phenols, saponins, and flavonoids may act as reducing agents during the synthesis of AgNPs [20,21].…”

Cannonball (Couroupita guianensis) is a tree belonging to the family Lecythidaceae. Various parts of the tree have been reported to contain oils, keto steroids, glycosides, couroupitine, indirubin, isatin, and phenolic substances. We report here the synthesis of silver nanoparticles (AgNPs) using cannonball leaves. Green synthesized nanoparticles have been characterized by UV-Vis spectroscopy, SEM, TEM, and FTIR. Cannonball leaf broth as a reducing agent converts silver ions to AgNPs in a rapid and ecofriendly manner. The UV-Vis spectra gave surface plasmon resonance peak at 434 nm. TEM image shows well-dispersed silver nanoparticles with an average particle size of 28.4 nm. FTIR showed the structure and respective bands of the synthesized nanoparticles and the stretch of bonds. Green synthesized silver nanoparticles by cannonball leaf extract show cytotoxicity to human breast cancer cell line (MCF-7). Overall, this environmentally friendly method of biological silver nanoparticles production provides rates of synthesis faster than or comparable to those of chemical methods and can potentially be used in various human contacting areas such as cosmetics, foods, and medical applications.

“…The prelims constituent's viz. carbohydrates, phenols, proteins, saponins, and tannins have been reported as potential reducing/ stabilizing agent in the synthesis of Ls-Ag NPs 47,48 . According to Saraswathi and Santhakumar (2017), the presence of tannins will help to cap the zirconium oxide nanoparticles and shown photocatalytic activity 37 .…”

Lagerstroemia speciosais commonly known as Banaba or Jarul which is used to get rid of various ailments such as fever, urinary infection, decongestion, diarrhoea, mouth ulcers, astringent, diabetes mellitus, kidney diseases, abdominal pains etc. The present work, describes the green synthesis of silver nanoparticles from ethanolic extract of fruits of L.speciosa (Ls-Ag NPs) and their analysis for antimicrobial activities. The characterisation of so obtained nanoparticles have been carried out with help of Field emission scanning electron microscopy (FESEM) and High-resolution transmission electron microscopy (HRTEM). Further, antimicrobial activities of ethanolic extract of fruits of L.speciosa(Ee-Ls), silver oxide (Ag2O), and Ls-Ag NPs have been examined by using well-diffusion method against two bacterial strains: Staphylococcus aureus (gram-positive) and Escherichia coli (gram-negative) and one fungal strain: Aspergillus niger.It has been observed that the biosynthesized Ls-Ag NPs possess much effective antimicrobial activity against selected strains as compared to Ee-Ls and Ag2O.
