plants for optimal growth requires absorb water and nutrients absorption from the soil. magnetic water downward movement of minerals and makes it easy for plants to absorb nutrients and water. this study was designed to investigate the effect of magnetic salt water on some quantity and quality characteristics of artichoke leaves. the experiment was factorial based on completely randomized desig...

this study was conducted to determine the effect of foliar salicylic acid (sa) and citric acid (ca) applications on growth, biochemical characteristics and essential oil content of thyme (thymus vulgaris l.) grown under field conditions. salicylic acid (0.5 and 1 mm) and citric acid (5 and 10 mm) were applied three times during the vegetation at 15 day intervals. results revealed that foliar ap...

The present study investigates a quantitative high performance thin layer chromatographic (HPTLC) method for chlorogenic acid and hyperoside determination from berry extracts. Chlorogenic acid and hyperoside were extracted using a methanol and water mixture and separated on a HPTLC 60F254 silica gel plates with ethyl acetate, acetic acid, formic acid and water 10:1.1:1.1:2.3 (v/v/v/v) as mobile...

Chlorogenic acid exists widely in edible and medicinal plants and acts as an antioxidant. It is known to exert antitumor activity via induction of apoptosis in many human cancer cells. However, its signaling pathway in human leukemia cells still remains unclear. Therefore, we investigated the roles of reactive oxygen species (ROS), mitochondria and caspases during chlorogenic acid-induced apopt...

ABSTRACT The efficacy of gamma irradiation is well versed as a method of decontamination for food and herbal resources. In the present study, Cichorium intybus L. roots were irradiated at multiple doses of 1, 2, 4, 6, 8 and 10 kGy by a cobalt-60 irradiator. The irradiated and non-irradiated control samples were evaluated for total phenolic contents, chlorogenic acid assay, 2,2-diphenyl-1-...

Variations in ̄avonoid and chlorogenic acid levels within fruit, within tree, between orchards, between cultivars and among mutants were characterised and quanti®ed in `Elstar' and `Jonagold' apples by reversed-phase high performance liquid chromatography (RP-HPLC). The sun-exposed skin of individual fruit had much higher cyanidin 3-galactoside (anthocyanin) and quercetin 3glycoside levels than...

gladiolus is one of the flowers that used on cut flower and garden plants. an experiment was conducted to study the effects of chemical treatments on the vase life of gladiolus cut flower cv. ‘rose supreme’ with ten chemical treatment using complete randomize design with 3 replications. gladiolus cut flower was harvested when the 2-3 lowest bud had start showing color then cut flower were treat...

Using HPLC, the seasonal changes in the phenolic compound content of the leaves of the Gemlik olive cultivar (Olea europaea L) has been investigated with respect to the effects on the alternate bearing of the cultivar. For this purpose, the leaf concentrations of oleuropein, chlorogenic acid, caffeic acid, 3-hydroxycinnamic acid, scopolin and pcoumaric acid were analyzed at 10 day intervals aro...

A simple and sensitive high performance liquid chromatographic method has been developed for the determination of chlorogenic acid (3-O-caffeoyl-D-quinic acid) in rat plasma and applied to its pharmacokinetic study in rats after peritoneal administration of compound Daqingye injection. Plasma samples are extracted with perchloric acid. HPLC analysis of the chlorogenic acid is performed on a C(1...

Coffee is one of mankind's most popular beverages obtained from green coffee beans by roasting. Much effort has been expended towards the chemical characterisation of the components of the roasted coffee bean, frequently termed melanoidines, which are dominated byproducts formed from its most relevant secondary metabolites - chlorogenic acids. However, impeded by a lack of suitable authentic re...
