BACKGROUND The rate of lead poisoning has decreased in recent years due to increased health control in industries that use this metal. However, it is still a public health problem worldwide. The use of various plants with chelating properties has been a topic of research today. In traditional medicine, it is said that Coriandrum sativum has chelating properties, but there is no scientific evide...

Moringa oleifera leaves extracted with methanol and dichloromethane were screened for antioxidant activity. The in vitro cancer antiproliferative and chemopreventive properties were also investigated. Radical scavenging assays with 1, 1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2 ́-azino-bis 3ethylbenzothiazoline-6-sulfonic acid (ABTS) were used to determine the antioxidant activity. The antiprolif...

Objectives: The genus Salvia is one of the most widespread members of the Lamiaceae family and S.virgata Jacq. decoction is traditionally used for leukemia in Turkey. In this study, water extract and methanol extract of S. virgata were investigated for their antiproliferative effects on Jurkat (Clone E6-1) leukemia cell lines and also GSH-Px, SOD and MDA levels were evaluated as oxidative stres...

The objective of this study was to investigate the antioxidant effects of methanolic extract of leaves of Hygrophila schulli against paracetamol induced liver damage. The material was dried in shade; they were powdered and extracted with methanol. The antioxidant effects of the methanol extract was assessed in paracetamol induced hepatotoxic rats. Alteration in the levels of antioxidant markers...

Jiaogulan (Gynostemma pentaphyllum; GP) contained a saponin glycoside which was related to ginseng saponin. The purpose of this study was to identify the main saponin in water extract GP compared to methanol and ethanol extract. The sample was prepared by alkaline cleavage, trimethylsilyl (TMS) derivatization and gas chromatographic-mass spectrometric (GC-MS) analysis comparison with standard g...

Lotus rhizome powder was extracted with solvents of different polarities. Antioxidant activities of the extracts were evaluated by a 2, 2'-diphenylpicrylhydrazyl (DPPH) assay and a beta-carotene bleaching assay, and compared with that of butylated hydroxyanisole (BHA) and ascorbic acid. Methanol showed the highest extract yield among all of solvents. Although acetone extract had the highest tot...

Successive solvent extract viz., petroleum ether, chloroform, methanol, ethanol and water extracts of bark of Betula utilis D. Don was evaluated for antibacterial activity, against fourteen important bacterial strains by agar-well diffusion method. Methanol extract was showed significant activity against all the tested bacteria followed by ethanol and aqueous extract. Chloroform and Petroleum e...

The present study investigates the antioxidant, anticancer, anticholinesterase, anti-genotoxic activities and phenolic contents of flower, fruit and seed methanol extracts of Hypericum retusum AUCHER. The amounts of protocatechuic acid, catechin, caffeic acid and syringic acid in methanol extracts were determined by HPLC. Total phenolic content of H. retusum seed extract was found more than fru...

In this study, the hepatoprotective effect of the methanol extract of aerial parts (shoot) from Otostegia persica Boiss (Golder) was investigated against the carbon tetrachloride (CCl4)-induced acute hepatotoxicity in male rats. Liver damage was induced through the oral administration of 50% CCl4 in liquid paraffin (2.5 mL/Kg bw, per os) 60 min after the administration of the methanol extract o...

Purpose: To evaluate the α-glucosidase inhibitory activity of Croton bonplandianum Baill as a probable remedy for the management of diabetes. Methods: Dichloromethane and methanol extracts were prepared and screened for their α-glucosidae inhibitory activity using standard in vitro α-glucosidae inhibition assay. Acarbose was used as positive control. Results: α-Glucosidae inhibition activity of...
