Tropical Fruit Peels as potential modifiers of rumen fermentation characteristics in goats: in vitro and in situ evaluations
Animal Production Science, 2020Co-Authors: Saeid Jafari, Ebrahimi, Yong Meng Goh, Mohamed Ali RajionAbstract:Context Methane (CH4) accounts for loss of dietary gross energy in ruminants and is a potent greenhouse gas. Feedstuffs that could alter ruminal fermentation by decreasing methane production without reducing total volatile fatty acid (VFA) concentration are desirable. Aims Tropical Fruit Peels, which can be simply collected and exploited, were compared with lucerne (Medicago sativa) in order to assess their potential to modify in vitro and in situ rumen fermentation and CH4 production of goats. Methods For the in vitro study, buffered rumen fluid (30 mL from each of four rumen-fistulated goats fed concentrate and lucerne hay) was mixed with 250 mg dry matter (DM) of each peel sample (dokong, mangosteen, papaya, pineapple, rambutan) and incubated for 48 h. A total of 250 mg DM of lucerne was mixed with rumen fluid as control. For the in situ study, dried samples (lucerne, and peel of dokong, mangosteen, papaya, pineapple, rambutan) were passed through a 2-mm sieve, weighed (5 g) into nylon bags, and individually placed in the rumen of four fistulated goats for 48 h. Key results In the in vitro study, tropical Fruit Peels lowered (P < 0.05) the production of CH4 compared with lucerne. Tropical Fruit Peels did not cause inhibition of total VFA (e.g. acetic, butyric and propionic acids) or decrease the concentration of ammonia-N compared with lucerne. In the in situ study, effective DM degradability of papaya (62.99%) and pineapple (54.45%) Peels were higher than of lucerne (51.04%). Potential DM degradability of pineapple (75.07%), dokong (72.62%), papaya (66.88%) and rambutan (59.15%) were also higher than of lucerne (57.55%). Conclusions Tropical Fruit Peels had no negative effect on ruminal fermentation and reduced CH4 production in vitro. However, in vivo studies should confirm these effects. Implications Tropical Fruit Peels may be suitable as a feedstuff for goats and could be an effective way to reduce methane gas emissions; however, more research under in vivo conditions is needed to elucidate the mechanisms by which tropical Fruit Peels mitigate of methane production in ruminants.

screening pesticide residues on Fruit Peels using portable raman spectrometer combined with adhesive tape sampling
Food Chemistry, 2019Co-Authors: Xinying Gong, Mi Tang, Zhengjun Gong, Zhongping Qiu, Dongmei Wang, Meikun FanAbstract:In this work, we report a simple and rapid surface-enhanced Raman scattering (SERS) method for the screening of pesticide residues on Fruit Peels using a portable Raman spectrometer. Adhesive tapes were used as the sampling media; the effectiveness of different tape brands was examined. Collection efficiencies were found to be 60.2 ± 7.6%, 54.3 ± 5.0%, and 52.3 ± 9.0% on glass, aluminum foil, and Fruit Peels, respectively. SERS was achieved by applying silver nanoparticles (Ag NPs) to the surface of the tape after analyte collection. Preparation of the Ag NPs was optimized for pesticide detection. The limit of detection of triazophos on apple Peels was 25 ng/cm2 with the portable Raman spectrometer. Considering the least favorable conditions, the calculated detection limit was 0.0225 mg/kg, which is an order of magnitude less than the maximum residue limit (MRL, 0.2 mg/kg) in China. The method is sufficiently sensitive for use in field analysis.

phytochemical investigation of the Fruit Peels of citrus reticulata blanco
Natural Product Research, 2010Co-Authors: Masroor M A Khan, Muhammad Ali, Prawez AlamAbstract:Phytochemical investigation of the Fruit Peels of Citrus reticulata Blanco (Rutaceae) resulted in the isolation of three new phytoconstituents along with n-hexacosonoic acid. Their structures have been established as 18βH-urs-5,11-dien-3β-ol-11-one-3β-D-glucopyranosyl-(4′→1′′)-D-glucopyranosyl-6′′-(3′′′,4′′′-dihydroxyl)-benzoate (reticulataursenoside), stigmast-5-en-3β-ol-3β-D-glucopyranosyl-4′-eicosanoate (citrusteryl arachidate), and lanost-5-en-3β-ol-3β-D-glucopyranosyl-4′-eicosanoate (citruslanosteroside) on the basis of spectral data analysis and chemical reactions.

bioactive glycoalkaloides isolated from solanum melongena Fruit Peels with potential anticancer properties against hepatocellular carcinoma cells
Scientific Reports, 2019Co-Authors: Mostafa I Fekry, Shahira M Ezzat, Maha M Salama, Ohoud Y Alshehri, Ahmed M AlabdAbstract:Hepatocellular carcinoma (HCC) is progressively increasing tumor with lack of accurate prognosis and inadequate systemic treatment approaches. Solanum sp. (such as Solanum melongena) is a folk herb which is reported to possess anticancer properties. In a continuity for our interest in pursuing the anticancer activity of compounds isolated from the Fruit Peels of Solanum melongena, the HPLC profiling and ESI-MS assessment for the methanolic extract evidenced the presence of bioactive glycoalkaloids (solasonine, solasodine and solamargine). These glycoalkaloids were isolated, purified and proved to possess in vitro cytotoxicity against human liver cancer cell lines (Huh7 and HepG2). Herein, we investigated the potential mechanism of action of these compounds using DNA content flow-cytometry and apoptosis/necrosis differential anaylsis using annexin-V/FITC staining. Solasonine, solasodine and solamargine inducd significant antiproliferative effect against liver cancer cells (Huh7 and HepG2) which was attributed to cell cycle arrest at S-phase. Solamargine, solasodine and solasonine induced significant apoptosis in Huh7 cells. Only solamargine-induced cell cycle arrest, was reflected as apoptotic cell killing effect against HepG2 cells. In conclusion, glycoalkaloids derived from Solanum melongena and particularly, solamargine are promising antiproliferative agents with potential anticancer effects.

in vitro fecal fermentation of high pressure treated Fruit Peels used as dietary fiber sources
Molecules, 2019Co-Authors: Viridiana Tejadaortigoza, Luis Eduardo Garciaamezquita, Ahmad E Kazem, Osvaldo H Campanella, Pilar M Cano, Bruce R Hamaker, Sergio O Sernasaldivar, Jorge WeltichanesAbstract:Fruit by-products are being investigated as non-conventional alternative sources of dietary fiber (DF). High hydrostatic pressure (HHP) treatments have been used to modify DF content as well as its technological and physiological functionality. Orange, mango and prickly pear Peels untreated (OU, MU and PPU) and HHP-treated at 600 MPa (OP/55 °C and 20 min, MP/22 °C and 10 min, PPP/55 °C and 10 min) were evaluated. Untreated and treated Fruit Peels were subjected to fecal in vitro fermentations. The neutral sugar composition and linkage glycosidic positions were related to the production of short chain fatty acids (SCFA) resulting from the fermentation of the materials. After HHP-treatments, changes from multibranched sugars to linear sugars were observed. After 24 h of fermentation, OP yielded the highest amount of SCFA followed by PPU and MP (389.4, 282.0 and 204.6 μmol/10 mg DF, respectively). HHP treatment increased the SCFA concentration of orange and mango peel by 7 and 10.3% respectively, compared with the untreated samples after 24 h of fermentation. The results presented herein suggest that Fruit Peels could be used as good fermentable fiber sources, because they yielded high amounts of SCFA during in vitro fermentations.
