The extract displayed the best inhibitory effect against Pseudomonas aeruginosa and its minimum inhibitory concentration (MIC) was 400 µg/ml, followed by Escherichia coli and Staphylococcus aureus with MIC 500 µg/ml. The presence of the extract significantly protected Sf9 cells against H2O2-induced cell death. In addition, the extract also showed DNA damage inhibitory effect in a concentration-dependent manner (0.5-4 mg/ml). However, at high concentration (7.5-30 mg/ml) it might induce damage to the DNA.
