Abstract
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.

One province in Indonesia is the province of western Sulawesi, has several types of medicinal plants that can be used in the treatment of various types of diseases
In this study,we investigated 6 selected, local putative medicinal plants for their potential antioxidant activities using scavenging free radical activity assays [2]
Summary
Indonesia has been known for its greatest biodiversity in the world, comprising tropical plants and marine biota. In the Indonesian territory there are about 30,000 species of plants and 7,000 of them are thought to have medicinal properties. One province in Indonesia is the province of western Sulawesi, has several types of medicinal plants that can be used in the treatment of various types of diseases. The efficacy of medicinal plants is highly dependent on the bioactive components contained therein. The medicinal plants are able to neutralize the cause of a disease. Based on the potential of medicinal plants in West Sulawesi, the analysis of bioactive components and antioxidant activity on the types of medicinal plants commonly used by local communities. In this study,we investigated 6 selected, local putative medicinal plants for their potential antioxidant activities using scavenging free radical activity assays [2]
