BACKGROUND Drynaria quercifolia L. (Family- Polypodiaceae) is a fern grows in Bangladesh used in traditional healing by the Garo tribe of Mymensingh district. In the current study, rhizomes and fertile foliage fronds of this plant have been investigated comprehensively to assess their in vitro membrane stabilizing, thrombolytic and antioxidant properties. METHODS Rhizomes and fertile foliage ...

The gastroprotective effect of the different fractions of Tribulusterrestris L. was investigated in the indomethacininduced gastric ulcer in rats at dose of 30 mg/kg body weight. The petroleum ether and aqueous fractions hada significant gastroprotective activity, while the chloroform and ethyl acetate fractions hada moderate gastroprotective activity. Keyword: Tribulusterrestris, Zygophyllacea...

INTRODUCTION Cancer causes about 13% of all deaths. According to the American Cancer Society, world-wide cancer deaths were 7.6 million in 2007. African Americans and other minorities are disproportionately affected. Effective cancer chemotherapy is scarce. This study is part of an ongoing search for potential cancer-fighting agents in medicinal herbs. In previous in-vitro studies, we have show...

In previous studies, the relaxant effect of Tymus vulgaris has been demonstrated on guinea pig tracheal chains. Therefore, in the present study, the relaxant effects of n-hexane, dichloromethane, methanol and aqueous fractions of Tymus vulgaris on tracheal chains of guinea pigs were examined. The relaxant effects of four cumulative concentrations of each fraction (0.4, 0.8, 1.2 and 1.6 g%) in c...

Objective: The use of drugs with herbal origin is increasing for treatment of gastrointestinal (GI) disorders. Rosa damascena (R. damascena) is a well-known plant suggested to have beneficial effect on GI system. In this study, the effect of aqueous fraction of R. damascena on the contractionsofisolated guinea pig ileum was investigated. Materials and Methods: Aqueous fraction of plant was obta...

In the present study, ethyl acetate, butanol and aqueous fractions derived from total methanol extract of Butea monosperma flowers were evaluated for radical scavenging activities using different in vitro models like reducing power assay, scavenging of 2,2 diphenyl-1-picrylhydrazyl (DPPH) radical, nitric oxide radical, superoxide anion radical, hydroxyl radical and inhibition of erythrocyte hem...

This study was aimed at investigating the antioxidant activity of Mangifera indica Linn., Cocos nucifera Linn., and Averrhoa carambola Linn. and their biological effect on human keratinocytes affected by the ultraviolet B (UVB), a major cause of cell damage and skin cancer through induction of DNA damage, production of reactive oxygen species (ROS), and apoptosis. The richest antioxidant activi...

OBJECTIVES This study was conducted to investigate the antioxidant potential of methanol extract and its derived fractions (hexane, ethyl acetate, butanol, and aqueous) of fruits of Monotheca buxifolia (Falc.) Dc., a locally used fruit in Pakistan. METHODS Dried powder of the fruit of M. buxifolia was extracted with methanol and the resultant was fractionated with solvents having escalating p...

Background & Aim: Platychaete aucheri (Boiss.) Boissis one of the Persian endemic plants and it belongs to Asteraceae family. The present study was aimed to evaluate the antimicrobial activity of crude methanolic extract and three sub-fractions of the flowering aerial parts of Platychaete aucheri against some gram-positive and gram-negative standard b...
