In order to establish the marker constituents of the natural antioxidant food-additive Eucalyptus leaf extract, the UV-absorbing constituents of two eucalyptus leaf extracts registered as food additives (eucalyptus A and B) were investigated. Several major peaks on the reversed-phase HPLC chromatogram of eucalyptus A were characterized as gallic acid, ellagic acid, 3-O-beta-D-glucuronides of qu...

Phenolic compounds like phenolic acids, flavonoids and tannins are important plant metabolites that are important for many pharmacological activites.we had earlier demonstrated the wound healing activity, analgesic and anti inflammatory of the methanolic extract. The extract was investigated to determine the nature of the phytoconstituents responsible for these activities and this led to the is...

By ANTONIo Gu oLA 1I, Do 1ENIco AG0sTIN0 AND EUGENE E. CLIFFTON T HROMBOSIS and embolism remain a most important factor in morbidity and mortality, particularly of hospitalized patients, despite all forms of treatment. A tendency to increased thrombosis has been reported in patients with cancer,13 myocardial infarction,4 atherosclerosis,5 pregnancy and puerpuerium,#{176}’T in postoperative or p...

Hepatocarcinoma (HCC) and colorectal cancer (CRC) are the most malignant tumors with increasing incidences of morbidity and mortality globally.The aim of the present study was to determine in vitro antitumor activity of quercetin, gallic acid, and ellagic acid against HCC and CRC. This was achieved through testing the effects of these compounds on HepG2 and HCT 116 cells, ranging from cell grow...

Polyphenol compositions and concentrations in skins and seeds of five muscadine grapes (cv. "Noble", "Alachua", "Carlos", "Fry", and "Granny Val") cultivated in the United States (Tallahassee-Florida, TA-FL) and South China (Nanning-Guangxi, NN-GX and Pu'er-Yunnan, PE-YN) were investigated, using ultra performance liquid chromatography tandem triple quadrupole time-of-flight mass spectrometry (...

Phytochemical investigation of the root extract of Terminalia glaucescens afforded three known compounds, ellagic acid 1, arjungenin 2, hypatic acid 3 and and a new triterpenoid named glaucescic acid, 2α,3α,6α,23-tetrahydroxyolean-12-en-28-oic acid 4. The structure and relative configuration of this new compound was elucidated on the basis of spectroscopic data, especially 2D NMR techniques.

HIGHLIGHTS Ellagic acid (EA) reduces oxidative damage and thus it can protect S. cerevisiae against to ROS. SDS-PAGE results reveal that EA induces total protein synthesis. cell development MDA levels increases GSH levels.
