Pesticide residue in food is of grave concern in recent years. In this paper, a rapid, sensitive, SERS (Surface-enhanced Raman scattering) active reduced-graphene-oxide-gold-nano-star (rGO-NS) nano-composite nanosensor was developed for the detection of acetamiprid (AC) residue in green tea. Different concentrations of AC combined with rGO-NS nano-composite electro-statically, yielded a strong SERS signal linearly with increasing concentration of AC ranging from 1.0 × 10−4 to 1.0 × 103 μg/mL indicating the potential of rGO-NS nano-composite to detect AC in green tea. Genetic algorithm-partial least squares regression (GA-PLS) algorithm was used to develop a quantitative model for AC residue prediction. The GA-PLS …

Journal of Food and Drug Analysis

Rubiscolin-6 is an opioid peptide derived from plant ribulose bisphosphate carboxylase/oxygenase (Rubisco). It has been demonstrated that opioid receptors could control glucose homeostasis in skeletal muscle independent of insulin action. Therefore, Rubiscolin-6 may be involved in the control of glucose metabolism. In the present study, we investigated the effect of rubiscolin-6 on glucose uptake in skeletal muscle. Rubiscolin-6-induced glucose uptake was measured using the fluorescent indicator 2-[N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl) amino]-2-deoxyglucose (2-NBDG) in L6 and C2C12 cell lines. The protein expressions of glucose transporter 4 (GLUT4) and AMP-activated protein kinase (AMPK) in L6 cells were observed by Western blotting. The in vivo effects …

Journal of Food and Drug Analysis

CCM111 is an aqueous extract of Antrodia cinnamomea (AC) that has exhibited anti-liver fibrosis functions. However, the detailed mechanisms of AC action against liver fibrosis have not been elucidated yet. The present research showed that CCM111 significantly lowered the levels of the hepatic enzyme markers glutamate oxaloacetate transaminase (GOT) and glutamic pyruvic transaminase (GPT), prevented liver damage and collagen deposition, and downregulated TGF-β/Smad signaling in a dose-dependent manner compared with CCl4 treatment alone. CCM111 markedly inhibited TGF-β Wnt and STAT3 signaling pathway-regulated downstream genes in the liver by next-generation sequencing. The antifibrotic mechanisms of CCM111 were further demonstrated in HSC-T6 …

Journal of Food and Drug Analysis

Peroxisome proliferator-activated receptor α (PPARα) is a nuclear hormone receptor that transcriptionally regulates lipid metabolism and inflammation; therefore, PPARα agonists are promising agents to treat dyslipidemia and metabolic disorders. PPARα full agonists, such as fibrates, are effective anti-hypertriglyceride agents, but their use is limited by adverse side effects. Hence, the aim of this study was to identify small molecules that can activate PPARα while minimizing the adverse effects. Antrodia cinnamomea, a rare medical mushroom, has been used widely in Asian countries for the treatment of various diseases, including liver diseases. Antcin B, H and K (antcins) and ergostatrien-3β-ol (EK100) are …

Extraction of bisphosphonates from biological fluids is important and time consuming step in sample preparation procedure. This paper describes a simple and green sample preparation technique for dispersive micro solid phase extraction (DMSPE) of alendronate sodium (ALS) from urine and serum samples prior to direct spectrofluorimetry (DSFL) and high performance liquid chromatography with fluorescence detection (HPLC-FLD), respectively. The DMSPE strategy is based on the selective chemisorption of ALS on zirconia nanoparticles (ZNPs) as an adsorbent followed by derivatization of the eluted analyte using o-phthalaldehyde (OPA) in the presence of 2-mercaptoethanol (2ME) at basic medium to form fluorescent species. The chemical …

Antioxidant Activity, Neuroprotective Properties And Bioactive Constituents Analysis Of Varying Polarity Extracts From Eucalyptus Globulus Leaves, E. González-Burgos, M. Liaudanskas, J. Viškelis, V. Žvikas, V. Janulis, M.P. Gómez-Serranillos Jul 2020

Antioxidant Activity, Neuroprotective Properties And Bioactive Constituents Analysis Of Varying Polarity Extracts From Eucalyptus Globulus Leaves, E. González-Burgos, M. Liaudanskas, J. Viškelis, V. Žvikas, V. Janulis, M.P. Gómez-Serranillos

Journal of Food and Drug Analysis

Eucalyptus globulus is employed as herbal tea and therapeutical purposes. In this work, it is investigated for first time the neuroprotective activities, based on antioxidant properties, of varying polarity extracts (acetone, ethanol and methanol) from E. globulus leaves and elucidate their main bioactive constituents. Methanol and acetone extracts contained the highest phenolic compounds amount and chlorogenic acid was the major compound identified by UPLC-ESI-MS/MS. Moreover, the three tested extracts showed significant antioxidant properties, varying their potency depending on the in vitro technique used. Furthermore, E. globulus extracts were effective in ameliorating H2O2-induced oxidative stress by increasing cell viability, GSH levels …

Development And Validation Of A Fast Gas Chromatography/Mass Spectrometry Method For The Determination Of Cannabinoids In Cannabis Sativa L, V. Cardenia, Toschi T. Gallina, S. Scappini, R.C. Rubino, M.T. Rodriguez-Estrada Jul 2020

Development And Validation Of A Fast Gas Chromatography/Mass Spectrometry Method For The Determination Of Cannabinoids In Cannabis Sativa L, V. Cardenia, Toschi T. Gallina, S. Scappini, R.C. Rubino, M.T. Rodriguez-Estrada

Journal of Food and Drug Analysis

A routine method for determining cannabinoids in Cannabis sativa L. inflorescence, based on Fast gas chromatography coupled to mass spectrometry (Fast GC/MS), was developed and validated. To avoid the decarboxylation of carboxyl group of cannabinoids, different derivatization approaches, i.e. silylation and esterification (diazomethane-mediated), reagents and solvents (pyridine or ethyl acetate), were tested. The methylation significantly increased the signal-to-noise ratio of all carboxylic cannabinoids, except for cannabigerolic acid (CBGA). Since diazomethane is not commercially available, is considered a hazardous reactive and requires 1-day synthesis by specialized chemical staff, silylation was used along the whole validation of a routine method. The method …
