Green Synthesis of Silver Nanoparticles Using Latex Extract of Thevetia Peruviana: A Novel Approach Towards Poisonous Plant Utilization

Sunlight Induced Mediated Silver Nanoparticles from Seeds of Thevetia peruviana L., Characterization and their Antifungal Efficacy against Curvularia lunata (Wakker) Boedijn

“…3). Similar result was observed by Brahmachari et al, 2014) when AgNPs were synthesized from Ocimum sanctum leaves extract but absorption maxima differed from Rupiasih et al, 2013) who used T. peruviana latex extract for the synthesis of AgNPs, where absorption maxima was 570 nm. The AFM image analysis revealed the topography, size of AgNPs.…”

“…Similarly, Rupiasih et al, (2013) synthesized AgNPs from T. peruviana latex extract and reported that biomolecules present in the latex responsible for the reduction of AgNPs. The UV-Visible spectrum of sunlight exposed AgNPs was 425 nm, autoclaved method 415-420 nm and whereas combination of both the method recorded 350 nm (Fig.…”

Biosynthesis of silver nanoparticles using aqueous leaf extract of Thevetia peruviana Juss and its antimicrobial activities

“…6c, inset). Rupiasih et al (2013) had reported that the size distribution of silver nanoparticles synthesized using the latex of Thevetia peruviana was between 10 and 30 nm. Elemike et al (2014) reported the size of silver nanoparticles synthesized using pineapple leaf as 12.4 nm.…”

“…This method is simple, costeffective, energy-saving and reproducible. Few of the plants and plant parts that have been reported in synthesizing silver nanoparticles are pineapple leaf (Elemike et al 2014), lemongrass (Cymbopogon flexuosus), Datura metel flower (Chandran et al 2012), Thevetia peruviana latex (Rupiasih et al 2013), Wrightia tinctoria (Bharani et al 2011), Solanum xanthocarpum (Muhammad et al 2012), Opuntia ficus (Silva-de-Hoyos et al 2012), Sphaeranthus amaranthoides (Swarnalatha et al 2012), Punica granatum (Naheed et al 2012) Citrullus colocynthis (Satyavani et al 2011), switchgrass (Cynthia et al 2012), Eucalyptus chapmaniana (Ghassan et al 2013), Acacia auriculiformis (Nalawade et al 2014), Ficus benghalensis, Azadirachta indica (Debasis et al 2015), etc. The biomolecules present in these plants are responsible for the formation and stabilization of silver nanoparticles (Iravani et al 2014).…”

Expeditious Synthesis of Noble Metal Nanoparticles Using Vitamin B12 under Microwave Irradiation

“…UV-visible absorption of the synthesized samples and vitamin B12 was investigated (Figure 3). It can be seen from Figure 3b that the absorbance at wavelengths ranging from 500 to 570 nm increased due to surface plasmon resonance (SPR) of silver nanoparticles [30] compared to that of vitamin B12; Ag nanoparticles normally exhibit resonance peaks at 400-450 nm. However, in the present study, the shift in resonance peak is due to the formation of different shapes of particles in the presence of vitamin B12.…”
