Over the past few decades, the green synthesis of nanoparticles has gained importance for their therapeutic efficacy and eco-friendly nature. Integrating green chemistry principles into multidisciplinary nanoscience research has paved the way for developing environmentally benign and sustainable methods for synthesizing gold and silver nanoparticles. In the present study, the flowers obtained from Clerodendrum infortunatum (L.), belonging to the family Verbenaceae, have been used for biosynthesizing silver nanoparticles (AgNPs) to evaluate the anthelmintic potential. UV–Vis spectroscopy, XRD, FTIR, SEM and TEM analyses were performed to ascertain the formation of AgNPs. Clerodendrum-derived AgNP (CLE-AgNP) has significantly affected the normal physiological functions of the poultry parasite Raillietina spp., a menace to the livestock industry. Our study manifests that CLE-AgNPs cause considerable distortion of the surface tegument of this cestode parasite leading to changes in the host-parasite interface. The histochemical localization studies of the tegument-associated enzymes viz. AcPase, AlkPase, ATPase and 5’-Nu, exposed to the drug, showed a substantial activity decline, thus establishing the anthelmintic potential of the CLE-AgNPs.

“…The various analytical and spectroscopic techniques such as UV-VIS, FT-IR, FE-SEM, XRD, BET, TG-DTA and HR-TEM envisage the formation of Pd@CNTs catalyst (See the SI for more details). Based on our recent findings in this direction [8] and with the help of literature precedents [9] it is evident that the phytochemicals present in the aq. extract of Gliricidia sepium leaves reduces the Pd (II) to Pd (0) (See SI for GC-MS chromatogram).…”

Environmentally amiable biogenic strategy for in‐situ one‐step synthesis of Pd‐NPs decorated on carbon nanotubes (CNTs) and its synthetic utility for C−H activation of benzamides to access isoquinolones has been reported for the first time. The phytochemicals present in Gliricidia sepium leaves extract was found to be serve as a reducing agent to reduce Pd (II) to Pd (0) and subsequently acts as a stabilizing agent. The formation of Pd@CNTs was confirmed by P‐XRD, FE‐SEM, EDX and ICP‐OES analysis technique with active Pd content 42.82 % w/w. In addition, DFT study of phytochemicals found in Gliricidia sepium leaves extract were conducted. The catalytic activity was showcased for the cost‐effective, step and atom economic synthesis of isoquinolones via C−H and N−H bond activation without the aid of external ligands. A series of isoquinolone derivatives were synthesized in good to excellent yields under air as a sole oxidant. In addition, catalyst recyclability and mechanistic experiments were deliberated. The Pd@CNTs unveiled superior catalytic activity and high durability towards hydrogen evolution reaction in acidic media. The Pd@CNTs attains the current density of 10 mA/cm2 at an over potential of 127 mV with a small Tafel slope of 41 mV/dec.

The sustainable and environmentally benign biogenic synthesis of manganese‐oxide nanoparticles (MnO2 NPs) in a single crystalline δ‐phase and its subsequent synthetic utility have been described. The synthesized δ‐MnO2 NPs were characterized using scanning electron microscopy (SEM), energy dispersive X‐ray (EDX), and X‐ray diffraction (XRD) analysis techniques. The detailed analysis envisages the reduction of Mn(VII) to Mn(IV) was facilitated by various phytochemicals present in the aq. mango leaves extract, avoiding the use of external ligand source. The synthesized δ‐MnO2 NPs were perceived in a single delta (δ) monoclinic crystalline phase, wherein a spherical agglomerated morphology was displayed with a particle size of <5 nm. Further, the utility of newly developed δ‐MnO2 NPs was showcased for alpha‐keto‐alkylation and quinoline synthesis via hydrogen autotransfer and the acceptorless dehydrogenative coupling strategy. Moreover, a series of control experiments, mechanistic elucidation, catalyst recyclability, and a dye removal study were demonstrated.
