Recombinant polyphenol oxidases for production of theaflavins from tea polyphenols.
Abstract
Theaflavins (TFs) have attracted much attention due to their various bioactivities in black tea. This paper describes the first trial for enzymatic production of TFs by recombinant polyphenol oxidases (PPOs). PPO genes were cloned from nine species and expressed in E. coli. Crude enzyme assays by LC-MS revealed that eight recombinant PPOs were active for TFs production from tea polyphenols as substrates. Much higher activities were observed for crude enzymes of Md2 from Malus domestica (apple), Pp4 from Pyrus pashia (pear), and Ej2 from Eriobotrya japonica (loquat). When immobilized on mesoporous ...

Neutrophil elastase inhibitory effects of pentacyclic triterpenoids from Eriobotrya japonica (loquat leaves)
ConclusionTCLL has a significant HNEI effect in vitro and a therapeutic effect on LPS-induced inflammation in a mouse model. Both the effects are more efficient than UA. Improved absorption of PTs in TCLL may be one explanation for these results.Graphical abstract (Source: Journal of Ethnopharmacology)

Molecules, Vol. 24, Pages 448: Microscopic Analyses of Fruit Cell Plastid Development in Loquat (Eriobotrya japonica) during Fruit Ripening
Changjie Xu
Plastids are sites for carotenoid biosynthesis and accumulation, but detailed information on fruit plastid development and its relation to carotenoid accumulation remains largely unclear. Here, using Baisha (BS; white-fleshed) and Luoyangqing (LYQ; red-fleshed) loquat (Eriobotrya japonica), a detailed microscopic analysis of plastid development during fruit ripening was carried out. In peel cells, chloroplasts turned into smaller chromoplasts in both cultivars, and the quantity of plastids in LYQ increased by one-half during fruit ripening. The average number of chromoplasts per peel cell in fully ripe fr...

Hepatoprotective Effect of Eriobotrya japonica Leaf Extract and Its Various Fractions against Carbon Tetra Chloride Induced Hepatotoxicity in Rats.
Authors: Shahat AA, Ullah R, Alqahtani AS, Alsaid MS, Husseiny HA, Al Meanazel OTR
Abstract
Eriobotrya japonica is traditionally used as an antipyretic, digestive, and diuretic agent. Its flowers possess free radical-scavenging, antioxidative, and hepatoprotective effects. We investigated the hepatoprotective potential of E. japonica leaf extract and its various fractions against hepatotoxicity in rats. Liver injury was stimulated by the oral administration of carbon tetrachloride (CCl4; 2.5 mL/kg b.wt.). Male albino rats (n = 55) were distributed arbitrarily into 11 groups: Group I, normal control group; ...

Floral nectar chitinase is a potential marker for monofloral honey botanical origin authentication: a case study from loquat (Eriobotrya japonica Lindl.)
Publication date: Available online 3 January 2019Source: Food ChemistryAuthor(s): Yue-Qin Song, Richard I Milne, Hong-Xia Zhou, Xue-Long Ma, Jiang-Yu Fang, Hong-Guang ZhaAbstractHoney,as a commercial product, is a target of adulteration through inappropriate production practices and deliberate mislabelling of botanical origin. Floral nectar protein could be a good marker for determining the source flowers of honey, especially monofloral honeys. Here, nectar and monofloral honey from Eriobotrya japonica Lindl. (loquat) were systematically compared, especially regarding proteomic and enzymatic activity. Using two-dimensional...

Genes, Vol. 9, Pages 639: De Novo Analysis Reveals Transcriptomic Responses in Eriobotrya japonica Fruits during Postharvest Cold Storage
This study aimed to explore the changes of loquat transcriptome during long-term cold storage. Our results showed that the gene expression patterns were differed among the five stages. The differentially expressed genes (DEGs) in response to cold storage were more intense and complex in earlier stage. The membrane-related genes preferentially responded to low temperature and were followed by intracellular-located genes. The cold-induced pathways were mainly concerned with signal transduction and secondary metabolism (i.e., lignin, pectin, cellulose, terpenoid, carotenoid, steroid) in the first three stages and were chiefly...

Antidiabetic and antihyperlipidemic effects of the flower extract of Eriobotrya japonica in streptozotocin-induced diabetic mice and the potential bioactive constituents in vitro
This study was designed to evaluate the effects of flower extracts of Eriobotrya japonica (EJ) on diabetes and hyperlipidemia for 4 weeks in streptozotocin (STZ)-induced diabetic mice. EJ treatment significantly lowered levels of blood glucose, HbA1C, plasma triglyceride (TG), and total cholesterol (TC) but increased the size of the islets of Langerhans within the pancreas. Membrane expression levels of glucose transporter 4 (GLUT4) and phospho-Akt in the skeletal muscles from EJ-treated STZ mice were increased, but G6Pase mRNA levels were decreased, contributing to EJ’s antidiabetic activity. EJ caused an increase in ...

Generation of (2-Nitroethyl)benzene and related benzenoids from L-Phenylalanine; flower scents of the Japanese Loquat Eriobotrya japonica [Rosales: Rosaceae].
Abstract
(2-Nitroethyl)benzene, methyl 4-methoxybenzoate and 4-methoxybenzaldehyde have been known as major scent components in flowers of the Japanese loquat Eriobotrya japonica [Rosales: rosaceae], together with 13 related benzenoids, including Z- and E-2-phenylacetaldoxime and benzyl alcohol. The scents air-trapped from a flowering panicle during 24 h incubation with d8-L-phenylalanine were composed of 15 deuterium labeled compounds {d6-styrene, d5-benzaldehyde, d7-2-phenylacetaldehyde, methyl d5-benzoate, d7 -2-phenylethanol, d7-2-phenylacetonitrile, d4-1,4-dimethoxybenzene, d7-Z-2-phenylacetaldoxime,...
