BACKGROUND The six organic solvent extracts of Artemisia nilagirica were screened for the potential antimicrobial activity against phytopathogens and clinically important standard reference bacterial strains. METHODS The agar disk diffusion method was used to study the antibacterial activity of A. nilagirica extracts against 15 bacterial strains. The Minimum Inhibitory Concentration (MIC) of ...

BACKGROUND Marine algae, also called seaweeds, are abundantly present in the coastal area of Iran, especially in Persian Gulf. These plants contain important phytochemical constituents and have potential biological activities. The present study investigated the presence of phytochemical constituents and total phenolic quantification of the seaweeds Gracilaria salicornia and Gracilaria corticata...

Increased production of reactive oxygen species has been implicated in the pathogenesis of cardiovascular disease (CVD), and enhanced endogenous antioxidants have been proposed as a mechanism for regulating redox balance. Nuclear factor (erythroid-derived 2)-like 2 (Nrf2) is a transcriptional regulator of phase II antioxidant enzymes, and activation of Nrf2 has been suggested to be an important...

Purpose: To determine the phytochemical content, and tyrosinase inhibitory and antimicrobial activities of the wood from Streblus ilicifolius (S. Vidal) Corner Methods: The dried wood of S. ilicifolius (8.70 kg) was extracted by maceration to give petroleum ether, ethyl acetate, ethanol and water extracts, respectively. Dopachrome method was used to determine antityrosinase activity. Agar disc ...

BACKGROUND Many oxidative stress related diseases are as a result of accumulation of free radicals in the body. A lot of researches are going on worldwide directed towards finding natural antioxidants of plants origins. The aims of this study were to evaluate in vitro antioxidant activities and to screen for phytochemical constituents of Helichrysum longifolium DC. [Family Asteraceae] aqueous c...

Andrographis alata Nees is an important medicinal plant. The current study was to investigate the antibacterial, antifungal activity and phytochemical analysis of the various leaf and stem extracts of A.alata. Methanol, ethanol, chloroform, acetone and petroleum ether extracts of shade dried plant leaf and stem of A.alata were tested for antibacterial, antifungal and phytochemical screening. Th...

The biochemical, phytochemical and antioxidant composition of root, stem, leaves and seeds of Cichorium intybus L was determined. A statistically significant difference (p>0.05) was observed among different parts of Cichorium intybus regarding the biochemical, phytochemical and antioxidant composition. The leaves were found to possess comparatively higher values of total sugars non-reducing sug...

Background & Aim: Fruits from the jujube plant (Ziziphus jujuba) possess health-promoting effects and medicinal properties. Jujube has a long history of usage as a remedy in Iranian traditional medicine and is recommended for the treatment of some diseases.
