Abstract

Using liquid media of Bacillus licheniformis, extraction with butanol and fractionation with n-hexane and ethyl acetate(EtOAc) were performed, From the EtOAc fraction, the isolation was also performed using chromatography. Three isoflavonoids were isolated from the liquid media of Bacillus licheniformis and identified as diadzein, genistein and genistin by Mass and NMR spectroscopic analysis.
