| Abstract | In Thailand, Scoparia dulcis is being used as a traditional medicine. The extract displays the best inhibitory effect against Pseudomonas aeruginosa and its minimum inhibitory concentration (MIC) was 400 ?g/mL followed by Escherichia coli and Staphylococcus aureus with MIC 500 ?g/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 higher concentrations (7.5-30 mg/mL) it might induce damage to the DNA. The prevention of DNA damage differs in different parts of the plant. To support secondary metabolite synthesis in different parts of S. dulcis, we investigated the expression of the Calmodulin gene that is involved in secondary metabolite production. The Calmodulin gene showed the highest expression in the fruit. This finding justifies the use of S. dulcis in the treatment of diseases caused by bacteria and free radicals. |
