Three new naphthoquinone derivatives from Diospyros maritima Blume. (1/60)
Three new naphthoquinone derivatives, 6-(1-ethoxyethyl)plumbagin (16), ethylidene-3,3'-biplumbagin (17), and ethylidene-3,6'-biplumbagin (18), were isolated, in addition to six known naphthoquinones, isozeylanone (10), 3,3'-biplumbagin (11), chitranone (12), methylene-3,3'-biplumbagin (13), 2,3-epoxyplumbagin (14), and 3,8'-biplumbagin (15), from the fruits of Diospyros maritima Blume (Ebenaceae). The structures of the new compounds were established by spectroscopic methods. The eight naphthoquinones 11-18 were examined for ichthyotoxic activity and germination inhibitory activity. The quinones 11, 12, and 14-16 showed strong ichthyotoxic activity and the quinone 14 mild germination inhibitory activity. (+info)Ty1-copia group retrotransposons in persimmon (Diospyros kaki Thunb.). (2/60)
We cloned and characterized Ty1-copia group retrotransposons in persimmon (Diospyros kaki Thunb.). Genomic DNA or methyl jasmonate (MJA)-treated cDNA were used as templates to amplify the reverse transcriptase region of Ty1-copia group retrotransposons. About 280 bp fragments were amplified and cloned, and 97 clones were sequenced. Forty-nine clones included frameshift or the stop codon, or both. Among 48 clones containing complete reading frames, 42 clones had unique nucleotide sequences. Alignment and phylogenetic analysis of putative amino acid sequences in the 42 clones indicated that these clones (named Tdk; retroTransposon in Diospyros kaki) fell into seven subgroups and six ungrouped sequences, indicating high sequence heterogeneity in Tdk clones. Phylogenetic analysis comparing unrelated plant species shows that some Tdk clones are more closely related to Ty1-copia group retrotransposons in the orders Solanales and Sapindales rather than to other Tdk clones. Southern blot analysis using Tdk2B, Tdk4c, Tdk6Ac, Tdk12K and Tdk13G clones as probes showed that persimmon and its related species, D. lotus, D. lotus var. glabba, D. oleifera, D. rhombifolia and D. virginiana, contained multiple Tdk-like sequences, indicating that homologous elements exist in other Diospyros species. (+info)pH regulates endoglucanase expression and virulence of Alternaria alternata in persimmon fruit. (3/60)
The phytopathogenic fungus Alternaria alternata produces one endo-1,4-beta-glucanase, AaK1, which is an important factor in disease development in persimmon fruit. During growth of A. alternata in media containing acidified yeast extract or cell walls from persimmon fruit, the fungus secreted ammonia and raised the medium pH. A rise in media pH from 3.8 to 6.0 in the presence of cell walls induced the expression of AaK1, whereas a glucose-induced decline in pH to 2.5 repressed transcription and enzymatic production. Treatments with buffered solutions at pH 6.0 during growth of A. alternata in the presence of glucose derepressed AaK1 expression and endo-1,4-beta-glucanase production and enhanced decay development on the fruit. The results suggest that conditions affecting environmental pH modulate gene expression of AaK1 and virulence of A. alternata in persimmon fruit (+info)Ethylene biosynthesis in detached young persimmon fruit is initiated in calyx and modulated by water loss from the fruit. (4/60)
Persimmon (Diospyros kaki Thunb.) fruit are usually classified as climacteric fruit; however, unlike typical climacteric fruits, persimmon fruit exhibit a unique characteristic in that the younger the stage of fruit detached, the greater the level of ethylene produced. To investigate ethylene induction mechanisms in detached young persimmon fruit, we cloned three cDNAs encoding 1-aminocyclopropane-1-carboxylic acid (ACC) synthase (DK-ACS1, 2, and -3) and two encoding ACC oxidase (DK-ACO1 and -2) genes involved in ethylene biosynthesis, and we analyzed their expression in various fruit tissues. Ethylene production was induced within a few days of detachment in all fruit tissues tested, accompanied by temporally and spatially coordinated expression of all the DK-ACS and DK-ACO genes. In all tissues except the calyx, treatment with 1-methylcyclopropene, an inhibitor of ethylene action, suppressed ethylene production and ethylene biosynthesis-related gene expression. In the calyx, one ACC synthase gene (DK-ACS2) exhibited increased mRNA accumulation accompanied by a large quantity of ethylene production, and treatment of the fruit with 1-methylcyclopropene did not prevent either the accumulation of DK-ACS2 transcripts or ethylene induction. Furthermore, the alleviation of water loss from the fruit significantly delayed the onset of ethylene production and the expression of DK-ACS2 in the calyx. These results indicate that ethylene biosynthesis in detached young persimmon fruit is initially induced in calyx and is modulated by water loss through transcriptional activation of DK-ACS2. The ethylene produced in the calyx subsequently diffuses to other fruit tissues and acts as a secondary signal that stimulates autocatalytic ethylene biosynthesis in these tissues, leading to a burst of ethylene production. (+info)Regulation of the peripheral body temperature by foods: a temperature decrease induced by the Japanese persimmon (kaki, Diospyros kaki). (5/60)
We investigated whether the ingestion of the Japanese persimmon (kaki, Diospyros kaki) could lower the human peripheral body temperature. It was found that the temperatures recorded at the foot and wrist were depressed after kaki consumption compared to after the same amount of water consumption. The effects of ingesting freeze-dried kaki and eating a cookie (as its nutritional counterpart) containing the same amount of carbohydrate, protein, fat, and water were compared. A similar temperature-reducing effect of kaki was observed. The recovery of finger temperature after soaking the finger in ice-cooled water was also studied. The temperature recovery was delayed after kaki consumption. It was thus quantitatively demonstrated that ingesting kaki indeed had the effect of lowering (or repressing the rise) of the peripheral human body temperature, as has been traditionally believed in China for many hundreds of years. (+info)beta-Galactosidase and its significance in ripening of "Saijyo" Japanese Persimmon fruit. (6/60)
The fruit extracts of ripening cv. Japanese Persimmon, "Saijyo", contained a number of glycosidases and glycanases. Among them, beta-galactosidase appeared to be the most significant, and the activity increased in parallel with tissue ripening. Persimmon beta-galactosidase was presented in at least three isoforms, beta-galactosidase-I (pI = 4.88), beta-galactosidase-II (pI = 6.76), and beta-galactosidase-III (pI = 7.05). beta-Galactosidase-III had exo-type galactanase activity, while the others did not. The activity of endo-type glycanases was a maximum in immature green or yellow fruits. The firmness of the pulp tissue decreased dramatically, and the amount of water-soluble polysaccharide (WSS) increased. The enzyme activities of exo-type glycosidases, especially beta-galactosidase, appeared maximal in mature red fruits. The amount of extractable pectin remained unchanged, although the galactose content of the high-molecular-weight fraction in WSS decreased dramatically. These results suggest that the ripening of persimmon was caused by the solubilization of pectic polysaccharide by endo-type glycanases and digestion by exo-type glycosidases. beta-Galactosidase, in particular, seemed to play a major role in ripening the fruit. (+info)Synthesis and characterization of hexadecadienyl compounds with a conjugated diene system, sex pheromone of the persimmon fruit moth and related compounds. (7/60)
Hexadecadien-1-ol and the derivatives (acetate and aldehyde) with a conjugated diene system have recently been identified from a pheromone gland extract of the persimmon fruit moth (Stathmopoda masinissa), a pest insect of persimmon fruits distributed in East Asia. The alcohol and acetate showed their base peaks at m/z 79 in a GC-MS analysis by electron impact ionization, but the aldehyde produced a unique base peak at m/z 84, suggesting a 4,6-diene structure. To confirm this inference, four geometrical isomers of each 4,6-hexadecadienyl compound were synthesized by two different routes in which one of two double bonds was furnished in a highly stereoselective manner. Separation of the two isomers synthesized together by each route was facilely accomplished by preparative HPLC. Their mass spectra coincided well with those of natural components, indicating that they were available for use as authentic standards for determining the configuration of the natural pheromone. Furthermore, other hexadecadienyl compounds, including the conjugated diene system between the 3- and 10-positions, were synthesized to accumulate the spectral data of pheromone candidates. 5,7-Hexadecadienal interestingly showed the base peak at m/z 80; meanwhile, the base peaks of its alcohol and acetate were detected at m/z 79 like the corresponding 4,6-dienes. The base peaks of all 6,8-, 7,9-, and 8,10-dienes universally appeared at m/z 67 like 9,11-, 10,12-, and 13,15-dienes, the spectra of which have already been published. Although 3,5-hexadecadienal was not prepared, base peaks at m/z 67 and 79 were recorded for the alcohol and acetate, respectively. (+info)Mechanism of gold adsorption by persimmon tannin gel. (8/60)
Gold adsorption by persimmon tannin (PT) gel from a solution containing hydrogen tetrachloroaurate(III) was examined. A flow-rate examination in a column system indicated the reduction of Au(III) ion to Au(0). XRD patterns clarified the existence of Au(0) on the gel which adsorbed gold. The gel could also adsorb colloidal Au(0) prepared independently. A model consisting of ligand exchange, Au(III) reduction to Au(0), and resulting Au(0) adsorption by PT gel was presented for the gold adsorption mechanism. (+info)"Diospyros" is a genus of evergreen or deciduous trees and shrubs, belonging to the family Ebenaceae. It includes several well-known species such as the persimmon (D. kaki) and ebony (D. ebenum). The name "Diospyros" comes from the Greek words "dios" meaning Zeus or god, and "pyros" meaning wheat, which may refer to the edible fruit of some species.
The trees in this genus are known for their hard, dense wood that is resistant to decay and insect attack, making them valuable for furniture-making, carving, and other woodworking applications. The fruit of some species, such as persimmon, are also eaten and valued for their high nutritional content.
It's worth noting that "Diospyros" is a scientific name used in the field of botany, and may not be commonly used in medical contexts unless referring to potential medicinal properties of plants in this genus.
Ebenaceae is a family of flowering plants that includes approximately 700 species, distributed across 5-6 genera. It is a widely distributed family, found in tropical and subtropical regions around the world. The family includes several economically important trees, such as those in the genus Diospyros, which includes persimmons and ebony.
Ebony trees are particularly known for their hard, dense, and dark-colored wood, which has been used for centuries to make high-quality furniture, musical instruments, and other decorative items. The wood is so dense that it sinks in water, and it has a fine texture with a smooth finish.
Ebenaceae family members are characterized by their opposite leaves, small flowers with four or five petals, and fleshy fruits. Some species have medicinal properties, and have been used in traditional medicine to treat various ailments, such as diarrhea, fever, and skin diseases. However, it is important to note that the safety and efficacy of these treatments have not been thoroughly studied or proven by scientific research.
I'm sorry for any confusion, but "New Caledonia" is not a medical term or concept. It is actually the name of a group of islands located in the southwest Pacific Ocean, east of Australia. The main island, Grande Terre, is known for its beautiful landscapes, which include mountains, beaches, and lagoons. New Caledonia is a special collectivity of France, and French is one of the official languages spoken there. If you have any questions related to medical terminology or health-related topics, I would be happy to help with those instead!
Proanthocyanidins are a type of polyphenolic compound that are found in various plants, including fruits, vegetables, and bark. They are also known as condensed tannins or oligomeric procyanidins (OPCs). These compounds are characterized by their ability to form complex structures through the linkage of flavan-3-ol units.
Proanthocyanidins have been studied for their potential health benefits, which may include antioxidant, anti-inflammatory, and cardiovascular protective effects. They have also been shown to have a positive impact on collagen stability, which may contribute to their potential role in promoting skin and joint health.
Foods that are rich in proanthocyanidins include grapes (and red wine), berries, apples, cocoa, and green tea. These compounds can be difficult for the body to absorb, but supplements containing standardized extracts of proanthocyanidins are also available.
It's important to note that while proanthocyanidins have shown promise in laboratory and animal studies, more research is needed to fully understand their potential health benefits and safety profile in humans. As with any supplement, it's always a good idea to talk to your healthcare provider before starting to take proanthocyanidins.
A plant extract is a preparation containing chemical constituents that have been extracted from a plant using a solvent. The resulting extract may contain a single compound or a mixture of several compounds, depending on the extraction process and the specific plant material used. These extracts are often used in various industries including pharmaceuticals, nutraceuticals, cosmetics, and food and beverage, due to their potential therapeutic or beneficial properties. The composition of plant extracts can vary widely, and it is important to ensure their quality, safety, and efficacy before use in any application.
