The 3-(4,5-dimethyl-2-thiazolinyl)-2,5-diphenyl-2-h-tetrazolylammonium bromide...
Citrus black spot (Phyllosticta citricarpa, CBS) is an important fungal disease that causes rind blemishes and affects quality of citrus fruits. The response to CBS in terms volatiles was evaluated using molecular sensory science approaches. Fifty twenty-one were identified the orange juice essential oil samples, respectively, via gas chromatography–mass spectrometry (GC–MS). total volatile content samples increased after infection, especially severe-infection group (SEG) moderate-infection...
Commercial mandarin juice often exhibits flavor deterioration during storage. The changes in volatile profiles were investigated stored under three different temperature conditions (4 °C, 25 and 40 °C). application of multidimensional gas chromatography-mass spectrometry/olfactometry (MDGC-MS/O) coupled with aroma extract dilution analysis (AEDA) identified 31 odorants juice, including seven off-flavor contributing compounds: methanethiol (unpleasant, repulsive), dimethyl sulfide (sulfur,...
Pomelo flowers emit a strong fragrance and give aromatic odors. Volatile compounds from pomelo were analyzed at three developmental stages in the main organs by molecular sensory science. A total of 134 volatiles including 25 odorants, gas chromatography–mass spectrometry/pulsed flame photometric detector (GC–MS/PFPD) multidimensional GC–MS/olfactory (MDGC–MS/O). The volatile content varied among different (stage-III > stage-II stage-I) (petal pistil stamen). Linalool was an important...
The publication of several high-quality genomes has contributed greatly to clarifying the evolution citrus. However, due their complex genetic backgrounds, origins and many citrus species remain unclear. We assembled de novo 294-Mbp chromosome-level genome a more than 200-year-old primitive papeda (DYC002). Comparison between two sets homologous chromosomes haplotype-resolved revealed 1.2% intragenomic variations, including 1.75 million SNPs, 149,471 insertions 154,215 deletions. Using this...
α-Terpineol, an abundant oxygenated monoterpene compound, shows a varied range of beneficial bioactivities. This study focused on the efficient extraction and purification α-terpineol from biotransformation limonene using Penicillium digitatum DSM 62840 mutant (PdTP1-overexpressed OE2 strain). The was primarily distributed in supernatant, with minimal association biomass. And optimal achieved ethyl acetate as extractant, which can directly obtain highest recovery without sequential...
The off-flavor produced after thermal stabilization of mandarin (Citrus reticulata, Blanco) juices has limited the production commercial juices. Methanethiol, a putrid-smelling sulfur volatile, been identified for first time in heated Identification was achieved using combination capillary gas chromatography with two dissimilar columns and dual sulfur-specific pulsed flame photometric detector selected ion mass spectrometry detection. Static headspace solid-phase microextraction quantitation...
The aim of this study was to analyze the non-volatile composition and antioxidant differences lemon essential oils (LEOs) obtained by cold-pressing vs. hydrodistillation. Pathological observations showed that LEO effectively inhibited liver injury caused oxidative stress, CPLEO more effective than HDLEO. increased serum T-AOC, SOD, GSH, GSH-Px levels while decreasing NO, COX-2, IL-6, IL-1β, IFN-γ, TNF-α in mice with damage. effects were stronger those HDLEO similar vitamin C. upregulated...
Light-induced off-flavor compounds in Ponkan mandarin juice were investigated during its shelf-life by headspace solid-phase microextraction multidimensional gas chromatography-mass spectrometry/olfactometry (MDGC-MS/O) and a GC-MS/pulsed flame photometric detector (GC-MS/PFPD). A total of 34 aroma-active with flavor dilution (FD) factors from 2 to 128 tentatively identified aroma extract analysis-MDGC-MS/O. Among them, light-induced compound high FD factor, methional (cooked potato), was...
The protective effects of the topical application orange peel cold-pressed oil (CPO), a rich polymethoxyflavones (PMFs) source, on ultraviolet B (UVB)-induced skin injury were studied. Depilated KM mice irradiated by UVB at one minimal erythemal dose every day and treated groups smeared with CPO before radiation. After two weeks we found that helped to maintain dermal structure enhanced serum levels tissue expression superoxide dismutase, catalase glutathione peroxidase. In lowered...
Gastrointestinal associated lymphoid tissue (GALT) is an important component of the mucosal immune system. It largest mass tissues in body and makes up more than 70% cells entire body. GALT considered to be origin systemic immunity consists solitary nodules, aggregated nodules (Peyer’s patches, PPs), scattered tissues, follicular epithelia. PPs play roles as antigen inductive sites system, which are mainly distributed intestine animals humans (especially ileum appendix). However, a special...
Citrus essential oils are widely used for aromatherapy and the alternative treatment of chronic diseases. Beyond aroma substances, they known to contain bioactive nonvolatile components; however, little knowledge has been gained about nonvolatiles in oil pomelo (Citrus grandis Osbeck), largest citrus fruit. The purpose this study was analyze oxygenated heterocyclic compounds (OHCs) evaluate their vitro antioxidant activities further development. Cold-pressed (CPEO) distilled (DEO) were...
The prophylactic effects of the polymethoxyflavones (PMFs) in long-leaf orange peel oil (OPO) were determined using an Nω-nitro-L-arginine-induced hypertensive rat model. OPO contained eight PMF components, namely sinensetin, hexamethoxyflavone, tetramethyl-O-isoscutellarein, nobiletin, tetramethyl-O-scutellarein, heptamethoxyflavone, 5-demethylnobiletin and tangeretin. After treatment with OPO, SP (systolic pressure) DP (diastolic rats reduced. NO (nitric oxide) contents serum, heart, liver...
In this paper, the cavitation characteristics of centrifugal blood pumps under variable speeds were studied by using ANSYS-CFX and MATLAB software. The study proposed a multi-scale model “centrifugal pump—left heart circulation”, analyzed pump. results showed that in impeller first appeared near hub at inlet impeller. As pressure decreased, gradually strengthened bubbles developed outlet intensity increased with increase speed. curve pump optimal auxiliary state was obtained, which could...
By establishing an effective ultraviolet B (UVB) radiation model of skin damage in mice, the effect lemon peel flavonoids (LPF) on was explored.
