Total anthocyanins in different cultivars of mulberry were measured and a process for the industrial preparation of mulberry antho-cyanins as a natural food colorant was studied. In 31 cultivars of mulberry, the total anthocyanins, calculated as cyanidin 3-glucoside, ranged from 147.68 to 2725.46 mg/L juice. Extracting and purifying with macroporous resins(More)
Nowadays, food industry is facing challenges in preserving better quality of fruit and vegetable products after processing. Recently, many attentions have been drawn to ginger rhizome processing due to its numerous health promoting properties. In our study, ginger rhizome slices were subjected to air-drying (AD), freeze drying (FD), infrared drying (IR),(More)
In this study, the effects of ultra-high pressure homogenisation (UHPH) processing at 200 MPa for 1-3 successive passes (inlet temperatures at 4°C) were compared with pasteurisation (95°C, 1 min) processing on phenolic compounds, antioxidant capacity (ORAC value) and anti-glucosidase of mulberry juice. Compared with thermal pasteurisation processing, the(More)
The chemical composition, antioxidant and antimicrobial activity of Pericarpium Citri Reticulatae (PCR) essential oil obtained using an improved Clevenger type apparatus were studied. Among the five different PCRs examined the highest yield of essential oil was found in Chachi 2004 (harvested and stored in 2004) and the lowest in Chachi 2008 (harvested and(More)
A simple and accurate method using high performance liquid chromatography (HPLC) with dual wavelength detection was developed to simultaneously determine the contents of one flavanone glycoside (hesperidin) and five polymethoxylated flavones (PMFs: sinensetin, 4',5,7,8-tetramethoxyflavone, nobiletin, tangeretin and 5-O-desmethyl nobiletin) in Pericarpium(More)
The title compound {systematic name: 4-[(E)-2-(3,5-dihy-droxy-phen-yl)ethen-yl]benzene-1,3-diol dihydrate}, C(14)H(12)O(4)·2H(2)O, a derivative of resveratrol, was isolated from mulberry. The linking C=C double bond has a trans conformation and allows the formation of a conjugated system throughout the mol-ecule. The dihedral angle between the benzene rings(More)
A new prenylxanthone, garcimangostanol (1), was isolated from the EtOAc-soluble partition of the ethanol extract of the pericarp of Garcinia mangostana L., along with three known compounds, namely 8-deoxygartanin (2), 1-isomangostin (3), and garcinone C (4). The structure of compound 1 was elucidated on the basis of its 1D, 2D NMR and MS data. Compounds 1-4(More)
Based on the protective performance of polydopamine nanospheres (PDANSs) for DNA against nuclease digestion and the specific recognition characteristic of aptamer, we have developed an enzymatic recycling signal amplification method for highly sensitive and selective detection of adenosine triphosphate (ATP). Fluorescence measurements were carried out to(More)
The aim of this study was to investigate the changes of quality attributes of Prunus mume fruits during deacidification using the fermentation of Lactobacillus fermentium. Results of HPLC analysis showed that the sucrose and glucose were dominant sugars, and citric acid was dominant organic acids in P. mume fruits. The level of citric acid reaches 39.3(More)
A novel, simple and selective electrochemical method was investigated for the simultaneous detection of dopamine (DA) and uric acid (UA) on a poly(l-lysine)/graphene oxide (GO) modified glassy carbon electrode (PLL/GO/GCE) by differential pulse voltammetry (DPV). The electrochemically prepared PLL/GO sensory platform toward the oxidation of UA and DA(More)
