Abstract:
Antioxidant capacity and antimicrobial activities of Inonotus hispidus extracts obtained with 70% ethanol and compound hispidin were investigated by Folin-Ciocalteu and NaNO2-Al(NO3)3 colorimetric methods.Total phenolics were (64.02±0.73) μg/mg (gallic acid equivalent) while the flavanoids were (5.74±0.13) μg/mg (rutin equivalent) in the extract.The antioxidant and antibacterial activities of 70% ethanol extracts and hispidin were determined.The results showed that DPPH and ?OH free radical-scavenging activities were found to exhibit about 90% inhibition，at concentration of 200 mg/kg.Positive correlations were found between total phenolic content in the mushroom extracts and their antioxidant activities.70% ethanol extract and hispidin showed narrow antibacterial activities against Staphyloccocus aureus and Bacillus subtilis.70% ethanol extracts inhibited the growth of the Escherichia coli，and inhibition values was 40.35% at concentration of 40.96 mg/mL.
