“…Clinical trials carried out on this plant showed its potential as anti-HIV, anticancer, antibacterial and antiviral agent (Peter et al, 1999). Previous phytochemical studies on E. agallocha revealed the presence of diterpenoids (ISI database, 2008;Ji-Dong et al, 2007;Li et al, 2007;Wang et al, 2006Kang et al, 2005), triterpenoids (Zou et al, 2006), fl avonoid (Konishi et al, 2003) and phorbole esters (Ericson et al, 1995). As part of our continuing phytochemical and bioactivity studies on Bangladeshi medicinal plants and also in other parts of the world (Alam et al, 2008a,b;Ali et al, 2008;Datta et al, 2007Datta et al, , 2004Saha et al, 2007;Uddin et al, 2007aUddin et al, -c, 2006aUddin et al, ,b, 2005Uddin et al, , 2004Rouf et al, 2006;Haque et al, 2004;Rahman et al, 2004;Delazar et al, 2006;Shoeb et al, 2007;Auzi et al, 2007;Zamani et al, 2007;Razavi et al, 2008), we now report on the neuropharmacological and antibacterial activities, and acute toxicty of the ethanol extract of the bark of E. agallocha in laboratory rodents as well as brine shrimp toxicity.…”
