“…Fat and carbohydrate are good sources of energy for livestock and humans. Crude fibre content in diets have been reported to aid digestive processes; promoting health in livestock and humans (Abubakar et al, 2016) and these findings are in line with previous reports indicating the bioactivity and application of peels of various plants (Abbas et al, 2018;Abdel Aziz et al, 2018;Ahad et al, 2018;Derakhshan et al, 2018;Garrafa-Galvez et al, 2019;Gurumallesh et al, 2019;Hu et al, 2019;Jridi et al, 2019;Kharchoufi et al, 2018;Kokila et al, 2016;Lakkab et al, 2019;Liu et al, 2017;Rodsamran and Sothornvit, 2019;Xu et al, 2019).…”

This study investigated the nutraceutical potential of ripe and unripe plantain fruit peels which are commonly discarded as food wastes. Proximate and mineral analyses of the samples were performed as per the standard methods of the Association of Official Analytical Chemists. Preliminary phytochemical screening of aqueous, acetone and methanol extracts of the peels was also carried out in accordance to standard methods. From the results of the study, acetone extract of the unripe peel showed the presence of eight phytochemicals while its ripe peel showed the presence of four. Aqueous and ethanol extracts of both peels showed the presence of same phytochemicals i.e., terpenoids, cardiac glycosides, phenols, flavonoids, alkaloids, reducing sugars and saponins. Meanwhile, tannins was absent in all three solvent extracts of both peels. Fat, ash, crude fibre and carbohydrate contents of the unripe peel were higher than those of the ripe. However, moisture and protein contents of the ripe peel were significantly higher (P < 0.05) than those of the unripe. Of all the nine essential minerals assayed (K, Na, Mg, Ca, P, Fe, Zn, Mn, Cu), concentrations of all except calcium were significantly higher (P < 0.05) in the unripe peel than those of the ripe peel. Notably, none of the heavy metals (Co, Cr, Cd, Pb, Ni) assayed was detected in both samples. This study concludes that ripe and unripe plantain fruit peels could serve as promising sources of nutrients and bioactive compounds essential for the health of both livestock and humans.

“…Also, Lycopersicon esculentum leaf extracts are used to synthesize SnO 2 nanoparticles for photodegradation of methylene blue. 193 The extract concentration affected the nanoparticles' crystal size, and the nanoparticles showed 100% efficiency in 2 hours of visible light irradiation. Honarmand et al 194 synthesized SnO 2 nanoparticles using the juice of Ziziphus ( jujube fruit) for the photocatalytic degradation of organic dyes.…”

“…To initiate photocatalytic degradation, 100 mg of the photocatalyst (SnO 2 ) was first added to 100 ml of a MB solution, which had a concentration of 15 mg/l (15 ppm) and a neutral pH (optimal concentration for photocatalytic tests [34]). Subsequently, the solution was mechanically stirred for 30 min in the dark to guarantee an adsorption-desorption equilibrium with the MB.…”

“…The h + reacts with a water molecule (H 2 O) to form a hydroxyl radical (OH • ), while the e − reacts • then reacts with H 2 O and forms more OH • . These two radicals are highly oxidizing species that react with MB molecules resulting in efficient degradation, producing H 2 O and carbon dioxide (CO 2 ) as reaction by-products [34]. The different reactions that occur during the process of photocatalytic degradation are shown below:…”

This research presents an alternative tin oxide (SnO 2) nanoparticles synthesis method using different concentrations of Citrus aurantifolia peel extract as reducing agent. We report the chemical identification protocol for polyphenols in the peels via FTIR, the characterization of the SnO 2 nanoparticles by FTIR, XRD, HRTEM, and UV-vis. The SnO 2 nanoparticles presented the Sn-O-Sn bond at 640 cm −1 and crystal growth with a clearly tetragonal structure. Depending on the amount of extract used, hemispherical nanoparticles of different sizes (5-12 nm) and band gap values ranging from 3.02 to 3.44 eV were obtained. Photocatalytic degradation studies of the synthesized SnO 2 were carried out using methylene blue under UV light. The sample with 4% extract of C. aurantifolia showed a degradation rate of about 96% at 120 min. The use of C. aurantifolia as a reducing agent in the synthesis of SnO 2 nanoparticles helps the properties and has control over the morphology of the nanoparticles.
