Pharmacological evaluation of Bangladeshi medicinal plants for antioxidant activity

Abstract

A growing body of evidence suggests that cellular damage or oxidative injury arising from production of free radicals or reactive oxygen species (ROS) are critical causative factors in the pathogenesis of many neurodegenerative disorders, inflammatory conditions, autoimmune diseases, diabetes, and gastrointestinal disorders. Results from biological and phytochemical studies indicate that medicinal plants have profound antioxidant potential that can be exploited further in the prevention and treatment of these devastating disorders. Here we have summarized the pharmacological and phytochemical investigations of 49 Bangladeshi medicinal plants representing 36 families with proven strong antioxidant properties. The medicinal plants were found to have profound antioxidant effect that can explain and justify some of their use in traditional medicine. These antioxidant medicinal plants may be considered as future leads to novel drug development for the management of various neurodegenerative and inflammatory disorders associated with oxidative cellular damage. © 2008 Informa UK Ltd.
