M. Abbas Ali Abu Sayeed Syed M. Abdus Salam Anwarul Islam Motiur Rahman G.R.M. Astaq Mohal Khan Seatara Khatun 122003217A terpenoid, 3-oxo-(20S, 24S)-epoxydammarane-19,25-diacetate (CP-1) isolated from the chloroform extract of barks of Caesalpinia pulcherrima was characterized on the basis of spectral data coupled with chemical evidence. The compound showed significant antibacterial activity against a number of pathogenic bacteria and prominent antifungal activity against a few fungi. The minimum inhibitory concentration (MIC) values against Bacillus cereus and Shigella dysenteriae were 16 μg ml-1 and 32 μg ml-1 respectively. The compound was found cytotoxic against brine shrimp and LC50 value was 8.41 μg ml-1. These findings suggested for further clinical trial.]]>Bauer, A.W., W.M.M. Kirby, J.C. Sherris and M.
