The use of the plant by traditional practitioners to treat bacterial and fungal diseases is therefore justified. REFERENCES Abolaji OA, Adebayo AH, Odesanmi OS (2007).

J. B. Fernandes*, A. V. Barros, M. S. Melo and I. C. Simoni Centro de P&D de Sanidade Animal, Instituto Biológico, São Paulo, Brazil. Accepted 22 June, 2010 In a screening of Brazilian plants, extracts from 27 species were assayed in vitro for antiviral activity against bovine and suid herpesviruses type 1. The plants considered promising as source of antiviral substances were those that presented viral inhibition index equal or more than 1.5 meaning a difference of viral titers between treated and untreated infected cells. Out of the 27 plants tested, extracts of Bumelia sertorum, Coffea arabica, Endopleura uchi, Leandra purpurescens, Psidium cattleianum and Uncaria tomentosa showed antiviral activity for both viruses. Extracts of Prunus myrtifolia and Symphyopappus compressus were active only against bovine herpesvirus while those of Bauhinia blakeana, Origanum vulgare, Ricinus communis and Tibouchina mutabilis inhibited only suid herpesvirus. Most of these plants are part of Brazilian folk medicine warranting the ethnopharmacology as an efficient strategy for selecting the plants for antiviral studies. Plants that presented activity against both animal herpesviruses are promising for further studies as antiviral components source. Key words: Brazilian plants, cytotoxicity, suid and bovine herpesviruses type 1, antiviral activity. INTRODUCTION Researches on natural products have significantly progressed over the last decades, mainly on plants corroborating their importance to the discovery of new biological and medicinal agents (Rates, 2001; Newman et al., 2003; Calixto, 2000). Treatment of viral infections with synthetic substances is often unsatisfactory and limited due a narrow spectrum of activity, limited therapeutic usefulness, toxicity and resistant viral strains (Martim and Ernest, 2003; Chattopadhyay and Naif, 2007). Many plants have been reported to have antiviral activity and may serve as promising sources of novel viral prototypes (Cowan, 1999; Jassim and Naji, 2003; Martim and Ernest, 2003; Chattopadhyay and Naif, 2007). In the veterinary area, the bovine (BoHV-1) and the suid (SuHV-1) herpesviruses are important pathogens, because of the significant economic losses incurred by diseases and trading restrictions. BoHV-1 is a major pathogen of cattle, causing infection bovine *Corresponding author. E-mail: judite@biologico.sp.gov.br. Tel: +551150871714. Fax: +551150871791. rhinotracheitis (IBR) and abortions (Muylkens et al., 2007). SuHV-1 causes the Aujeszky’s disease (ADV) or pseudorabies (Nauwynck, 1997; Groff et al., 2005). The aim of the present work is to assess the in vitro antiviral activity of 27 Brazilian plant extracts against these two animal herpesviruses together with studies of cytotoxicity, because Brazil has the largest tropical forest in the world, where medicinal plants are most abundant. MATERIALS AND METHODS Plants The 27 plant species used in this study are as shown in Table 1. Majority of the plants were collected in Serra do Itapeti Municipal Natural Park, Mogi das Cruzes, São Paulo (SP) State, Brazil during 2004 to 2005. Only Coffea arabica, Ligustrum lucidum, Morus nigra, Potomorphe umbellata and Ricinus communis were from the park to the Instituto Biológico, São Paulo/SP. The plant specimens were identified and authenticated by botanist Dra. Inês Cordeiro, of the Instituto de Botânica de São Paulo, São Paulo by comparison with exsiccates deposited at this herbarium. The crude aqueous extracts (CAE) were obtained from dried leaves which were powdered, dissolved in sterile distilled water (10%, w/v) and maintained overnight at 4°C. Then, CAE were filtered on filter paper and were
