Cork tree, (Sonneratia caseolaris L.), family Sonneratiaceae, is a typical plant in mangroves. It is widespread in tropical and subtropical tideland throughout the World. It is reported to possess many medicinal properties. For searching new pharmacological activities of Cork tree, the total phenolic contents, antioxidant activities and the electric eel acetylcholinesterase inhibitions and the ...

The contributions of individual amino acid residues or groups of amino acids to antioxidant activities of some food protein hydrolysates were investigated using partial least squares (PLS) regression method. PLS models were computed with amino acid composition and 3-z scale descriptors in the X-matrix and antioxidant activities of the samples in the Y-matrix; models were validated by cross-vali...

The antioxidant activity of water extracts (cold and hot) of six caffeine products were carried out. The extracts were screened for total polyphenol contents and antioxidant activity using DPPH, ABTS methods and reducing power method at 50 and 100 μg/ml after 15 min and 30 min using DPPH, ABTS BHA and Caffeine as standard compounds. The results indicated that, the hot water extracts for differe...

Background: Hemidesmus indicus is an important medicinal plant and extensively used in Ayurvedic and Unani system of medicine. The aim of the study was to evaluate the antioxidant, hypoglycaemic and hypolipidemic potential of methanolic extract of roots of Hemidesmus indicus (HIE) in streptozotocin (STZ) induced diabetic mice. Methods: HIE was analyzed by LC-MS to determine its phytochemical co...

Recently, interest in plant-derived food additives has grown mainly because synthetic antioxidants suffer from several drawbacks. Some plants are traditionally used for both food and medicine in Iran. Aqueous and methanolic extracts of Smyrnium cordifolium Boiss leaves and stems and Sinapis arvensis L leaves, stems and flowers were prepared and evaluated for their total phenolic content (TPC), ...

BACKGROUND There is an interest in finding new and safe antioxidants from natural sources such as medicinal plants. OBJECTIVES The aim of this study was to evaluate the antioxidant activity of ten Iranian medicinal plants extracts. MATERIALS AND METHODS For antioxidant activity, the radical scavenging activity, reducing power and phenolic contents of ethanol plant extracts were determined. ...

Recombinant SPLTI-a [sweet potato leaf trypsin inhibitor-a] overproduced in E. coli (M15) was purified by Ni-chelated affinity chromatography. The molecular mass of SPLTI-a is ca. 8000 Da as determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). SPLTI-a was examined using different antioxidative models (Total antioxidant status, reducing power method, Fe-chelating a...

OBJECTIVE The present study was designed to evaluate the antioxidant, analgesic, and anti-inflammatory activities of the methanolic extract of Piper betle leaves (MPBL). MATERIALS AND METHODS MPBL was evaluated for anti-inflammatory activity using carrageenan-induced hind paw edema model. Analgesic activity of MPBL was evaluated by hot plate, writhing, and formalin tests. Total phenolic and f...

OBJECTIVE To examine the antioxidant activity and total phenolic content of different solvent fractions of Pedalium murex (P. murex) Linn fruits (Family: Pedaliaceae) as well as the correlation between the total antioxidant capacity and total phenolic content. METHODS In the present study, the antioxidant activities of P. murex were evaluated using six in-vitro assays, namely total antioxidan...

BACKGROUND Free radical-induced oxidative stress is the root cause for many human diseases. Naturally occurring antioxidant supplements from plants are vital to counter the oxidative damage in cells. The main objective of the present study was to characterize the antioxidant and antiproliferative potential of rice bran extracted from an important Indian rice variety, Njavara and to compare the ...
