diospyros leucomelas/抗真菌藥

In vitro biological activities including phytotoxic, antifungal activities as well as acute toxicity of the methanol extract, fractions and/or isolated compounds from the stem bark of Diospyros canaliculata were investigated. Well agar diffusion and macrodilution assays were used for investigating

A preparative overpressure layer chromatography (OPLC) method was successfully used for the separation of two new natural compounds, 4-hydroxy-5,6-dimethoxynaphthalene-2-carbaldehyde (1) and 12,13-didehydro-20,29-dihydrobetulin (2) together with nine known compounds, including 7-methyljuglone (3),

Dietary supplements have exhibited myriads of positive health effects on human health conditions and with the advent of new technological advances, including in the fields of proteomics, genomics, and metabolomics, biological and pharmacological activities of dietary supplements are being evaluated

In this study the methanol/dichloromethane (1:1) extract and plumbagin isolated from extract of stem barks of Diospyros crassiflora were tested for their antifungal activity against 12 strains of yeast pathogens and filamentous fungi: Candida albicans, Candida glabrata, Candida krusei, Candida

We have purified a 27 kDa protein from the overripe fruits of Diospyros texana to homogeneity by ammonium sulfate precipitation, DEAE-Sepharose and C18 reversed phase column chromatographies. The purified protein inhibited the growth of the agronomically important pathogen Phytophthora infestans,

A novel chitinase from the persimmon fruit was isolated, purified and characterised in this report. The Diospyros kaki chitinase (DKC) was found to be a monomer with a molecular mass of 29 kDa. It exhibited optimal activity at pH 4.5 with broad pH stability from pH 4.0-9.0. It has an optimal

The water maceration and methanolic extract of the stem barks of Diospyros bipindensis, which is a medicinal plant used in Cameroon by Baka pygmies, revealed a complex high-performance liquid chromatography (HPLC) profile primarily composed of coumarin and naphthoquinone glycosides. The methanolic

Deoxypreussomerin derivatives, palmarumycins JC1 (1) and JC2 (2), and two dimeric naphthoquinones, isodiospyrin (3) and its new derivative isodiospyrol A (4), were isolated from dried fruits of Diospyros ehretioides. Structures of the isolated compounds were elucidated by spectroscopic analyses.

The aim of this study was to evaluate the pharmacological efficacy of persimmon leaves in two glaucoma models, microbeads-induced ocular hypertension (OHT) and DBA/2 mouse. Thus, we demonstrated that Ethanol Extract of Diospyros kaki (EEDK) reduced elevated intraocular pressure (IOP) in both mouse

Synapse dysfunction is an early hallmark of Alzheimer's disease (AD), and was considered to be closely related to memory loss. The molecular mechanisms that trigger synapse loss and dysfunction remain poorly understood. Increasing evidence shows a link between Rho GTPases and synapse plasticity. Rho

Diospyros kaki L. or Costata cultivar is the main persimmon variety progressively consumed in the Egyptian market and exportation. The objective of this study was to investigate the bioprotective effects of the alcoholic extract of fruits as well as leaves of D. kaki using in-vivo rat models.

Retinal ganglion cell (RGC) death is part of many retinal diseases. Here, we report that the ethanol extract of Diospyros kaki (EEDK) exhibits protective properties against retinal degeneration, both in vitro and in vivo. Upon exposure to cytotoxic compounds, RGC-5 cells showed approximately 40%

Flavonoids from the leaves of Diospyros kaki L (FLDK-P70) are main therapeutic components of NaoXingQing, which is a novel and patented Traditional Chinese Medicine drug used for the treatment of syndrome of apoplexy for years in China. The present study investigated the effects of FLDK-P70 on

Field trials have been carried out to determine the residues of the fungicide pyrimethanil in persimmon (Diospyros kaki Linn) after field treatment. Three treatments using pyrimethanil (PYR 30% WP) were carried out on persimmon trees at a recommended dose rate: the former was sprayed at two

The leaves of persimmon (Diospyros kaki L.) have long been used in Chinese medicine for the treatment of paralysis, frostbite, burns, and to stop bleeding. Flavonoids of persimmon leaves (FPL) are known for their antioxidant activity in murine osteoblast MC3T3-E1 cells, but their mechanisms in
