Microwave-assisted extraction of phenolics from pomegranate peels: Optimization, kinetics, and comparison with ultrasounds extraction
Publication date: Available online 24 January 2019Source: Chemical Engineering and Processing - Process IntensificationAuthor(s): Kyriakos Kaderides, Lygeri Papaoikonomou, Melania Serafim, Athanasia M. GoulaAbstractRecently, there has been much interest in the phenolics of pomegranate peels, because of their health benefits, such as antioxidant activity. Thus, the objective of this work is to optimize an efficient alternative and “green” technique for the extraction of phenolics from pomegranate peels. Microwave-assisted method was found to increase extraction yield, but mainly to shorten the treatment time by over 60 ...

Chemical peeling for acne and melasma: current status and innovations.
Authors: Conforti C, Zalaudek I, Vezzoni R, Retrosi C, Fai A, Fadda S, Di Michele E, Dianzani C
Abstract
The skin is a dynamic organ that continuously eliminates an infinite number of keratinized cells through physological mechanism. Chemical peeling is a widely used cosmetic procedure in medical practice. This technique consists of the application of one or more chemical ablative agents to the skin's surface in order to induce keratolysis or keratocoagulation. Exfoliation is followed by skin and epidermal regeneration from the adjacent epithelium and skin adnexa. Moreover, through an inflammatory reaction and the ...

Remediation of Azo-dyes based toxicity by agro-waste cotton boll peels mediated palladium nanoparticles
Publication date: Available online 10 December 2019Source: Journal of Saudi Chemical SocietyAuthor(s): Boya Palajonnala Narasaiah, Badal Kumar MandalAbstractThe present study reports an environmental benign route for the synthesis of palladium nanoparticles (Pd NPs) using agro-waste empty cotton boll peels aqueous extract for the first time. Surface Plasmon Resonance (SRP) band in absorption spectrum of Pd NPs at 275 nm confirmed the formation of Pd NPs by using UV-Vis spectroscopy. Crystalline nature of Pd NPs was confirmed by powder XRD analysis. Size and morphology was studied by transmission electron microscopy (TEM). ...

Isolation and Characterization of Neuroprotective Components from Citrus Peel and Their Application as Functional Food.
Abstract
The elderly experience numerous physiological alterations. In the brain, aging causes degeneration or loss of distinct populations of neurons, resulting in declining cognitive function, locomotor capability, etc. The pathogenic factors of such neurodegeneration are oxidative stress, mitochondrial dysfunction, inflammation, reduced energy homeostatis, decreased levels of neurotrophic factor, etc. On the other hand, numerous studies have investigated various biologically active substances in fruit and vegetables. We focused on the peel of citrus fruit to search for neuroprotective components and found that:...

Bio-regeneration of spent Fe3O4 laden quaternary-ammonium shaddock peel after perchlorate capture: Considering the oxygen, coexisting anions, bio-fouling and indirect bio-regeneration
Publication date: 15 May 2017 Source:Chemical Engineering Journal, Volume 316 Author(s): Yuanfeng Qi, Xing Xu, Cao Qi, Xi Fei A new bio-sorbent based on the shaddock peel was prepared for perchlorate capture. The shaddock peel was introduced with quaternary-ammonium groups and Fe3O4 nanoparticles, forming the Fe3O4 laden quaternary-ammonium shaddock peel (Fe3O4-QA-SP). Bio-regeneration of perchlorate laden Fe3O4-QA-SP considering the oxygen, coexisting anions, bio-fouling and indirect bio-regeneration was conducted. Results indicated that the bio-reduction rate increased as the increase in the amounts of perchlorate laden...

Lemon-Peel extract ameliorates rheumatoid arthritis by reducing xanthine oxidase and inflammatory cytokine levels
Publication date: Available online 16 August 2018Source: Journal of the Taiwan Institute of Chemical EngineersAuthor(s): Guo-Sheng Zou, Su-Juan Li, Shao-ling Zheng, Xia Pan, Zheng-ping HuangAbstractWe investigated the effect of a lemon-peel extract in a rat model of rheumatoid arthritis and SW1353 chondrocytes. The rats were divided into control (sham), rheumatoid arthritis (control), extract (150 mg/kg bwt) and extract (300 mg/kg bwt) groups. Pyrogallic acid, caffeic acid, eugenol, p-coumaric acid, p‑hydroxyl benzoic acid, resorcinol, salicylic acid, luteoline, quercetin, chrysin, and luteolin-3‑methoxy‑7-rutino...

Biomineralization of orange peel peroxidase within metal organic frameworks (OPP–MOFs) for dye degradation
Publication date: Available online 16 February 2019Source: Journal of Environmental Chemical EngineeringAuthor(s): Manish Salgaonkar, Shamraja S. Nadar, Virendra K. RathodAbstractIn an attempt to make the biocatalyst preparation economically viable, the peroxidase enzyme extracted from orange peel (Citrus sinenses, a fruit waste) was immobilized within metal-organic framework (MOF) via self-assembled biomineralization method. The synthesis of OPP-MOF was accomplished by simply mixing 2-methylimidazole (24 mmol), zinc acetate (8 mmol) and orange peel extract at room temperature within 30 min. The obtained OPP-MOF was ...
