Sukiman and Partomuan SimanjuntakPotency of medicinal plant is related to microorganisms lived in the plant tissue. Those microorganisms are known as endophytic microbes that live and form colonies in the plant tissue without harming its host. Each plant may contains several endophytic microbes that produce biological compounds or secondary metabolites due to co-evolution or genetic transfer from the host plant to endophytic microbes. Endophytic fungi research done for turmeric plant (Curcuma longa L.) gave 44 isolated fungi as results. Those 44 fungi isolated were fermented in Potato Dextrose Broth (PDB) media, filtered, extracted with ethylacetate and then were analyzed by Thin Layer Chromatography (TLC) method and tested for their antioxidant activity by radical scavenging method. The antioxidant activity of the ethylacetate filtrate extracts either from Sukabumi or Cibinong were higher than the biomass extracts. There were 6 fungi that showed antioxidant activities over 65 persen, i.e., with code name K.Cl.Sb.R9 (93.58 persen), K.Cl.Sb.A11 (81.49 persen), KCl.Sb.B1 (78.81 persen), KCl.Sb.R11 (71.67 persen) and K.Cl.Sb.A12 (67.76 persen) from Sukabumi and K.Cl.Cb.U1 (69.27 persen) from Cibinong. These results showed that bioproduction by endophytic microbes can gave potential antioxidant compounds.
