Aim: The present study was intended to develop some novel imidazole derivatives via multi-component reaction catalysed by Ceric Ammonium Nitrate (CAN) in polyethylene glycol-400 (PEG-400) and its HMG-CoA reductase inhibitory activity for benefit in atherosclerosis. Methods: The one-pot synthesis has been achieved by taking benzyl, benzaldehyde, 3-amino-1, 2, 4triazole-5carboxylic acid (0.01 mol...

The anti-oxidative potential of laminarin (L), fucoidan (F) and an L/F seaweed extract was measured using the DPPH free radical scavenging assay, in 25% pork (longissimus thoracis et lumborum (LTL)) homogenates (TBARS) (3 and 6 mg/mL) and in horse heart oxymyoglobin (OxyMb) (0.1 and 1 mg/mL). The DPPH activity of fresh and cooked minced LTL containing L (100 mg/g; L100), F100 and L/F100,300, an...

The antioxidant potential of the 99% methanolic extract of leaves of Muntingia calabura was assessed by using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and total phenolic content was measured by Folin-Ciocalteau (FC) by Singleton and Rossi using Gallic acid and Tannic acid as the calibration standard. Moreover Muntingia calabura leaf extract showed strong reducing power and significant antioxidant a...

Phytochemicals profiling is important for the isolation of new and novel chemical substances. The current finding is directed to the detection of different classes of chemical constituents responsible for antioxidant properties of Euphorbia prostrate.The crude methanolic extract and various solvent isolated fractions of E. prostrate showed the presence of Alkaloids, Terpenoids, Saponins, Tannin...

Most of the biological properties myrtle (Myrtus communis L.) are linked to antioxidant activity phenolic compounds present in extracts. In this study, content total phenols, tannins, and anthocyanins acidified ethanol extracts berries leaves five cultivars was quantified during whole fruit development. some development stages, (AA) both tissues evaluated with FRAP, ABTS, DPPH, ?-carotene assay...

In the present study, the phenolic (Folin-Dennis) and flavonoid (colorimetric assay) constituents, antioxidant [2,2-diphenyl-2-picrylhydrazyl hydrate (DPPH) assay] and cytotoxic activities of an aqueous extract (AE) of Centella asiatica leaves were investigated. The aqueous extract (50 g/L) was obtained by infusion followed by cold maceration for 24 h. The levels of phenolic and flavonoid compo...

The aqueous extract of C. borivilianum (250 mg/kg for 7 days) significantly reverted the elevated levels of plasma glucose, triglycerides, cholesterol and serum corticosterone and also reduced the ulcer index, adrenal gland weight more as effectively as the standard drug (diazepam) in rats. At 125 mg/kg po, it showed a mild anti-stress activity. Under in vitro 1,1-diphenyl-2-picrylhydrazyl (DPP...

The known flemingins A-C (1-3) and nine new chalcones, named flemingins G-O (4-12), along with deoxyhomoflemingin (13) and emodin (14) were isolated from a leaf extract of Flemingia grahamiana. The isolated chalcones were found to have a geranyl substituent modified into a chromene ring possessing a residual chain, as shown by spectroscopic methods. The leaf extract showed an IC50 value of 5.9 ...

In the present biological studies, several pharmacological investigations were carried out to ascertain analgesic, and antioxidant activity of the ethanol extract of the leaves of Cerbera manghas Linn. (FamilyApocynaceae). The presence of reducing sugars, tannins, steroids, alkaloids, glycosides, and flavonoids were indicated by the phytochemical analysis of the extract. To evaluate analgesic a...
