Abstract

Abstract A study to observe toxic effect of ethanol extract of Pterospermum celebicum Miq. by using Brine Shrimp Lethality Test (BSLT) has been carried out. The method to do this study was irritation test of cream formula of the extract. The aim of this study was to collect data about toxicity of fractionated extract of P. celebicum Miq. on Artemia salina by using BSLT method according to LC 50 value obtained from probit analysis. The extract was extracted by maceration method using ethanol as solvent which was then formulated as cream containing 3% of P. celebicum Miq. extract.
