Abstract

The genus, Viburnum Linn., belonging to the family Caprifoliaceae includes about 200 species throughout the world and some 17 species growing in India at an altitude from 1800 – 2500 ft. Many of these species have been investigated for their pharmacognostic features and phytochemical elaboration lacking information on biological potentials of them. So, the current study undertaken casts some scientific information on phytochemical based pharmacological screening such as anti-inflammatory and analgesic activities, using Methanol soluble fractions of aqueous root extracts of three species – Viburnum punctatum Buch.-Ham. ex D. Don (VPMF), Viburnum coriaceum Blume (VCMF) and Viburnum erubescens Wall. ex DC (VEMF) – in suitable animal models. The acute oral toxicity study was carried out according to the OECD (Organization for Economic Co-operation and Development) guidelines 423 (Acute toxic class method). In acetic acid induced writhing in mice, a significant reduction in writhing was observed with all the fractions than the control group (p
