Wide application of nanoparticles motivates the need for synthesising them. Here, a nontoxic, eco-friendly, and cost-effective method has been established for the synthesis of silver nanoparticles using extracts of lemon peel (Citrus limon), green orange peel (Citrus sinensis), and orange peel (Citrus tangerina). The synthesised nanoparticles have been characterised using UV-visible absorptionspectroscopy, Fourier transform infrared spectroscopy, and transmission electron microscopy (TEM). The UV-visible absorption spectrum of these synthesised silver nanoparticles shows an absorption peak at around 440 nm. TEM images show different shaped particles with various sizes. Furthermore, the antibacterial activity of silver nanoparticles was appraised by a well-diffusion method and it was observed that the green synthesised silver nanoparticles have an effective antibacterial activity against Escherichia coli and Staphylococcus aureus. The outcome of this study could be beneficial for nanotechnology-based biomedical applications.

Bedbugs are harmful human blood-sucking ectoparasites. The disadvantages of a bedbug bite cause itching, redness bumps, secondary infections, and anemia in children. Bedbugs controller so far uses harmful chemical pesticides, but reappearance of bedbugs indicates less effective chemical pesticides, and becomes a serious problem. So it needs safer controller for human health. This study aims to analyze the d-Limonene activity of orange peel (Citrus sinensis L.) in controlling the bedbug infestation (Cimex cimicidae). The study was conducted through 5 stages: d-Limonene isolation, GC-MS characterization, bioassay Y test d-Limonene nanoparticles, SEM characterization, and d-Limonene activity test on bedbug. The results showed that the essential oil of orange peel contained the main compounds as d-Limonene (90.018%), 1,6-Octadien-3-ol, 3,7-dimethyl- (3,017%), β-Myrcene (2.071%), Octanal (0.349%), 1-Octanol (0.589%), 1R-α-Pinene (0.688%), 6-Octen-1-ol, 3,7-dimethyl- (0.667%), 3-Cyclohexene-1- methanol, α, α, 4-trimethyl-, (S) - (1.453%), and Bicyclo [3.1.1] heptane, 6.6-dimethyl-2-methylene-, (1S) - (1.147%). The Bioassay Y test shows that d-Limonene was both repellent and fumigant, d-Limonene nanoparticles had uneven and irregular surface morphology, and in the flea activity test showed more than 50% bedbugs death. These research concluded that d-Limonene compounds from sweet orange peel had activity to control the bedbugs.

The removal of heavy metal ions Cr (VI) and Zn (II) from aqueous solution using theskin of orange peel (Citrus sinensis) as an adsorbent under different experimentalconditions was investigated in this study. The concentrations of the metal ions adsorbedwere determined by atomic absorption spectroscopic (AAS) method. The parametersinvestigated were temperature, contact time, adsorbent dosage, initial metal ionsconcentration and pH. It was observed that the white inner skin of orange removed more ofCr (VI) than Zn (II) metal ions in all the adsorption experiments. The optimum removal ofthe Cr (VI) and Zn (II) metal ions occurred at pH 3 and at temperature 30°C. Application ofthe Langmuir isotherm to the systems yielded maximum adsorption capacity of 8.068 (mg/g)and 1.078 (mg/g) for Cr (VI) and Zn (II) metal ions respectively.Keywords: Orange peel; Adsorption; Heavy metals; LangmuirDOI: 10.3126/jncs.v26i0.3628Journal of Nepal Chemical SocietyVol. 26, 2010Page:31-39

In this study we evaluated the protective effects of jamun Syzygium cumini seed and orange Citrus sinensis peel extracts on renotoxicity of microcystin LR in male rats. Groups A-F were given daily treatments for 30 days. Group A (Control): No treatment was given; Group B: microcystin (10 µg/kg body wt); Group C: microcystin (10 µg/kg body wt) and jamun seed extract (200 mg/kg body wt); Group D: microcystin (10 µg/kg body wt) and orange peel extract (200 mg/kg body wt; Group E: orange peel extract (200 mg/kg body wt); Group F: jamun seed extract (200 mg/kg body wt). Kidney were fixed at 15th and 30th day after the treatments. In 15 day MCLR (group B) treated rats shrunken glomeruli, hypertrophy of epithelial cells of tubules. vacuolation of cytoplasm and obliterated tubular lumina were noticed. In MCLR+JSE (group C) and MCLR+OPE (group D) treated rats almost similar changes were noticed as seen in MCLR treated rats. In OPE (group E) and JSE (group F) treated rats no visible morphological alterations were nojticed. Following 30 day MCLR treatment (group B), increased cellularity of glomeruli, no space between the Bowman's capsule and glomerulus, glomerular degeneration, dilated tubules, separation of tubular epithelial cells from underlying basement membrane, tubular vacuolization and degeneration with necrotic nuclei in lumina and deposition of eosin-positive material in the tubules were observed. In MCLR+JSE (group C) and MCLR+OPE (group D) treated rats the glomeruli were swollen showing increased cellularity. No degeneration was noticed in glomeruli. Tubules were dilated, however, at few places few epithelial cells were degenerating. Necrotic nuclei were not seen in tubular lumina. In OPE (group E) and JSE (group F) treated rats the kidney exhibited no histological changes.
