The roots of Viburnum punctatum, Viburnum coriaceum and Viburnum erubescens were collected from Nilgiri Hills and Coimbatore, Tamilnadu and taxonomically authenticated. Herbarium of the species was submitted to the museum of the place of research studies. The samples were shade dried for a week. About 500 g of powdered samples were extracted with petroleum ether (60 - 80º C), benzene, and 75 % v/v ethanol successively in a soxhletor one by one and followed by determination of percentage extractives. The extracts were qualitatively tested for their different chemical constituents. The ethanolic extracts were selected for further investigations such as determination of total phenolic content and in vitro anti-oxidant potential. It was revealed that all three species exhibited an appreciable anti-oxidant potential against reference compound subjected, and anti-oxidant potential among three species was ascending in series V.coriaceum>V.punctatum>V.erubescens
