Triphala is an age old commonly used Ayurvedic powdered preparation in Indian systems of medicine. This well known formulation is made by combining Terminalia chebula, Terminalia belerica and Embellica officinalis, in equal proportions. The formulation is prescribed in the first line treatment of many aliments and is used as laxative, detoxifying agent and rejuvenator. Terminalia chebula and Te...

abstract leukemia is known as the world’s fifth most prevalent cancer. new cytotoxic drugs have created considerable progress in the treatment, but side effects are still the important cause of mortality. plant derivatives have been recently considered as important sources for the treatment of various diseases, including cancer. gallic acid (ga) is a polyhydroxyphenolic compound with a wide ran...

Gallic acid is a normal constituent of many edible foods, thus directly interacts with epithelial tissue in intestine. In the present study, the effect of gallic acid on intestinal alkaline phosphatase (IAP) and peptidase activities in rat intestine was evaluated. Gallic acid (0.27-0.5 mM) inhibited activities of leucine aminopeptidase (LAP) and y-glutamyl transpeptidase (y-GTP) by over 90%, co...

Purpose: To investigate the physicochemical properties and DPPH radical scavenging activity of gallic acid–lecithin complex Methods: The complex of gallic acid with lecithin was prepared by solvent method. The physicochemical properties of the complex were investigated by ultraviolet-visible spectrometry (UV), infrared spectrometry (IR), scanning electron microscopy (SEM), differential scanning...

Hydrolyzed gallic acid in Potentilla chinensis Ser. was determined by HPLC using Potentilla chinensis Ser. as a model drug with chromatographic conditions as follows: Hypersil C18 column (250 mm × 4.6 mm, 5 μm); mobile phase methanol-0.05% aqueous solution of phosphoric acid (10:90); volume flow 1.0 mL/min; detection wavelength 271 nm; column temperature 25°C; and injection volume 20 μL. Inject...

objective: it is generally agreed that most of the phenomena observed during brain ischemia and reperfusion can be explained by the damage to membrane structure. oxidative stress is resulted in an imbalance between high consumption of oxygen and low levels of endogenous antioxidants. it is known that gallic acid (ga) is a strong antioxidant. the present study was carried out to evaluate the eff...

The present study aimed to evaluate the protective effect of gallic acid on gastric mucosal lesions caused by ischemia-reperfusion (I/R) injury in rat. Forty male rats were randomly divided into sham, control (I/R injury) and three gallic acid-pretreated groups. To induce I/R lesions, the celiac artery was clamped for 30 min and then the clamp was removed to allow reperfusion for 6 hr. Pretreat...

Although multiple studies have revealed that gallic acid plays an important role in the inhibition of malignant transformation, cancer development, and inflammation, the molecular mechanism of gallic acid in inflammatory diseases is still unclear. In this study, we identified gallic acid from Rosa rugosa as a histone acetyltransferase (HAT) inhibitor with global specificity for the majority of ...

The MeOH extract of the seeds of Rhynchosia volubilis (Leguminosae) showed antiproliferative activity against human gastric adenocarcinoma [MK-1, 50% growth inhibition (GI50): 25 microg/ml], human uterus carcinoma (HeLa, GI50: 30 microg/ml), and murine melanoma (B16F10, GI50: 8 microg/ml) cells. Bioactivity-guided fractionation resulted in the isolation of gallic acid methylester (1), gallic ac...
