Sesuvium portulacastrum L., (family: Aizoaceae), commonly known as “sea purslane” has long been used as food and traditional medicine. Traditionally plants are used in the treatment of epilepsy, conjunctivitis, dermatitis, haematuria, leprosy, purgative, fever, kidney disorders, and scurvy and also used to therapy toothache. Leaves have acidulous flavor of sorrel as well as antiscorbutic. The p...

Lycium species is a popular medicinal plant in the traditional Chinese medicine and Lycium ruthenicum is a native medicinal plant of Iran. Lycium genus has several biologically important properties too. Investigation of chemical composition of ethyl acetate extract of this plant is the goal of this study. Two coumarins (Scopoletin and Sculetin) and Methyl-2-hydroxy-4-undecanoxy-trans-cinamate w...

Ginger (Zingiber officinale) is a well-known and widely used herb, which contains several interesting bioactive constituents and possesses health-promoting properties. The proximate, mineral, antinutrient, amino acid, and phytochemical components of two varieties of ginger (Zingiber officinale) were investigated. Amino acid composition was determined using standard analytical techniques. The re...

Received: Revised: Accepted: November 13, 2014 February 12, 2015 February 21, 2015 Gentamicin-induced nephrotoxicity is associated with free radicals generation in kidney tissue. Medicinal plants contain bioactive constituents that act as natural antioxidants, which can protect the biological system from oxidative stress. In this study, phytochemical constituents of aqueous extract of Calotropi...

Plants and their active constituents play an important role in the prevention of a variety of ailments. Most of the species of the Genus Vitex are used therapeutically in ancient Indian systems of medicine especially, Ayurveda and Siddha. The genus Vitex contains about 270 species distributed around the world. These species contain a variety of potentially bioactive molecules, such as iridoids,...

BACKGROUND Free radical stress leads to tissue injury and can eventually to arthritis, atherosclerosis, diabetes mellitus, neurodegenerative diseases and carcinogenesis. Several studies are ongoing worldwide to find natural antioxidants of plant origin. We assessed the in-vitro antioxidant activities and screened the phytochemical constituents of methanolic extracts of Pyrostegia venusta (Ker G...

Eryngium L. is the largest and arguably the most taxonomically complex genus of the family Apiaceae. The genus has approximately 250 species throughout the world, with the center of diversity in South America. Some Eryngium species are cultivated as ornamental, vegetable, or medicinal crops for folk uses. With increasing chemical and biological investigations, Eryngium has shown its potential a...

Homalium zeylanicum is a rare and phytochemically less explored tropical tree. Chemical examination of bark and leaf of this species yielded phenolic compounds 3Phenyl coumarin (1) and 4'-O-Methyl-Epigallo catechin (2). The structures of the compounds were established on the basis of various NMR spectral data. The extracts of bark, leaf and their isolated compounds showed both antioxidant and a...

Both artificial and naturally occurring antioxidants have been reported to play major roles in protecting membranes and tissues from free radical and xenobiotic-induced oxidative damage (Burton, 1989; Carini et al., 1990). Most living organisms harbour both enzymatic and non-enzymatic systems that protect them against excessive reactive oxygen species. However, various external factors (smoke, ...

How do people make sense of the sequential images in visual narratives like comics? A growing literature of recent research has suggested that this comprehension involves the interaction of multiple systems: The creation of meaning across sequential images relies on a "narrative grammar" that packages conceptual information into categorical roles organized in hierarchic constituents. These imag...
