INTRODUCTION Stinging nettle (Urtica dioicd L.) is one of the most valuable plants used in phytotherapy. The herbal raw material is a herb (Urticae herba), leaves (Urticae folium), roots (Urticae radix) and seeds (Urticae semina). This plant is a good source of vitamins, minerals, fibre, protein and biologically active compounds with antioxidant properties. The literature provides limited infor...

The aim of this study was the evaluation of the antioxidant capacity of Cotoneaster melanocarpus Lodd. and the identification of antioxidant active constituents of this plant. C. melanocarpus Lodd. is a shrub indigenous to Mongolia and used in Traditional Mongolian Medicine as a styptic. Before extraction, the plant material was separated into three parts: young sterile shoots, older stems and ...

Article history: Received on: 09/12/2014 Revised on: 17/01/2015 Accepted on: 22/02/2015 Available online: 27/05/2015 Plant derived drugs have been a part of the evolution of human healthcare for thousands of years. The present study was carried out to evaluate the antioxidant potential of ethanolic extract of Tabernaemontana divaricata on DEN initiated and Fe-NTA promoted renal damage in rats. ...

Oxidative stress plays a main role in the development of diabetes complications. The impairment of gonadal antioxidant potential and endocrine disturbance in diabetic males causes testicular damage and failure in sperm production. Plants have been widely used to control diabetes due their hypoglycemic and antioxidant potential, contributing towards the recovery of testicular function. Current s...

Elevated atmospheric CO2 can stimulate plant growth by providing additional C (fertilization effect), and is observed to mitigate abiotic stress impact. Although, the mechanisms underlying the stress mitigating effect are not yet clear, increased antioxidant defenses, have been held primarily responsible (antioxidant hypothesis). A systematic literature analysis, including "all" papers [Web of ...

BACKGROUND Populations in Africa mostly rely on herbal concoctions for their primarily health care, but so far scientific studies supporting the use of plants in traditional medicine remain poor. The present study was undertaken to evaluate the anti-hyperglycemic effects of Picralima nitida (seeds), Nauclea latifolia (root and stem) and Oxytenanthera abyssinica (leaves) commonly used, in diabet...

A detailed study has been performed on the antioxidant activity of the acetone and methanol extracts of the stem bark of the plant, Shorea roxburghii. The total phenolic content and antioxidant activity of the extracts were determined by DPPH, radical scavenging, ferric ion reducing power, hydroxyl radical, ABTS(.) radical scavenging and hydrogen peroxide scavenging activities. Reducing efficie...

OBJECTIVE There has been a growing interest in finding plants with biological active ingredients for medicinal application. MATERIALS AND METHODS Three colors of petals of Althaea officinalis (A. officinalis) flowers, i.e., pink, reddish pink, and white were examined for total antioxidant activity and flavonoids content. RESULTS The reddish pink flowers of A. officinalis have more antioxidan...
