Objective: Phytochemical screening as well as several bioassays was performed on the extracts of aerial parts of Caragana jubata. Methods: Extraction of C. jubata was carried out by solvents of increasing polarity. The Phytochemical screening of extracts was carried out using standard procedures. Furthermore, extracts were also evaluated for (i) antibacterial assay, (ii) brine shrimp lethality ...

background & aim: medicinal plants can be a good replacement for common cancer treatment including chemotherapy, radiation therapy and surgery because they don’t have many side effects. the aim of this study was to investigate the effect of temperature on the free radical scavenging in the presence of medicinal plants. experimental: for determination of free radical scavenging activity was...

A series of new 5-(2-amino-5-methylthiazol-4-yl)-1,3,4-oxadiazole-2-thiol derivatives 6(a-j) were designed and synthesized with various substituted aldehydes. The chemical structures were confirmed by elemental analyses, FT-IR, (1)H NMR, and mass spectral studies. The antioxidant activity of the synthesized compounds was evaluated by 2,2-diphenyl-1-picrylhydrazyl (DPPH), hydroxyl, nitric oxide,...

The contents and antioxidant ability of various classes of phenolic compounds present in the seeds of twenty soybean hybrids were evaluated. Total phenolics, tannins and proanthocyanidins were determined spectrophotometrically, after extraction of seeds with 70% aqueous acetone. In addition, the flavonoid contents were determined. The antioxidant activity of aqueous acetone extracts was evaluat...

From the MeOH extract of the leaves of Eugenia uniflora eight compounds were isolated, including one sterol, β-sitosterol (1); two triterpenes, betulinic acid (2) and centelloside C (8); three flavonoids, myricetrin (3), myricetin 3-O-(4’’-O-galloyl)-αL-rhamnopyranoside (4), and myricetin 3-O-β-D-glucopyranoside (5); and two megastigmanes, actinidioionoside (6), and (6S,9R)-roseoside (7). All t...

Soluble flaxseed gum (SFG) was extracted from flax (Linum usitatissimum) hulls using hot water, and its functional groups and antioxidant properties were investigated using infrared spectroscopy and different antioxidant assays (2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid (ABTS), reducing power capacity, and β-carotene bleaching inhibition assay)...

Aiming at the exploration of herbal use by society, crude extracts of the seeds of some commonly used medicinal plants (Vitis vinifera, Tamarindus indica and Glycin max) were screened for their free radical scavenging properties using ascorbic acid as standard antioxidant. Free radical scavenging activity was evaluated using 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical. The overall antioxi...

Background: DNA damage is one of the major consequences of radia on exposure onto the biological systems. A series of compounds including flavanoids were found to render DNA protec on against radia on damage. In this study we elucidated the poten al of ru n and ru n hydrate to protect plasmid DNA against damage induced by irradia on. Materials and Methods: DPPH and hydroxyl radical scavenging a...

The present investigation was an attempt to evaluate the antioxidant and anticancer property of Anisaldehyde in vitro. Anisaldehyde is an organic compound that consists of a benzene ring substituted with an aldehyde and a methyl group. It is very effective as a carminative (to relieve gas pains). In this study, free radical scavenging activity was evaluated using DPPH (α,α-diphenyl-β-crylhydraz...

the essential oil of verbena officinalis growing in iran was extracted using hydro-distillationmethod and the antibacterial and antioxidant activities were evaluated. the antibacterial activity of the essentialoil against a gram-positive (s. aureus atcc25923) and gram negative (e. coli atcc 25922) were examined.the results obtained revealed that the essential oil exhibited variable levels of an...
