The main objective of this study was the screening of some selected medicinal plants very popular in Provinsi of western Sulawesi, with respect to antioxidant capacity, and bioactive compound. All plants were extracted with the conventional method, maceration with methanol. Bioactive compound was measured by GCMS-QP2010 Ultra Shimadzu. The antioxidant capacity of the plant extracts was measured by their ability to scavenge free radicals such as DPPH (2,2-diphenyl-1-picrylhydrazyl). These extracts resulted in a rapid increase and decrease of the absorbance and showed different hydrogen-donating capacity towards the DPPH radical. A lot of differences found and showing anti-oxidant activity of methanol extracts of different plant species. Among the species, methanol extract of Ficus septica, Cordoline sp., Celotia argantea, Physalis angulate, Kalandioe pinnata and Melostoma polyanthum, showed the maximum scavenging capacity of over 70. © Published under licence by IOP Publishing Ltd.
