Abstract
Antibiotic resistance is continually increasing and is a major problem in global public health. Thus, searching for novel agents to fight bacterial pathogens is an important choice to solve the problem. This study focused on the estimation of total phenolic content, antioxidant activity, and antibacterial activity of Boesenbergia and Alpinia genera. The result showed that all genera were abundant sources of total phenolic content, antioxidant activity and antibacterial activity against Staphylococcus aureus and Escherichia coli. The highest total phenolic content and antioxidant activity was found in ethanol extracts of Boesenbergia rotunda (L.) Mansf. ‘Pluang’ (137.22 mg gallic acid/g extract) and Boesenbergia rotunda (L.) Mansf. ‘Rakkluay’ (1/EC50=0.0714), respectively. Of Alpinia genus, the highest total phenolic content (133.16 mg gallic acid/g extract) and antioxidant activity (1/EC50 =0.0401) were found in ethanol extracts of Alpinia malaccensis (Burm.f.) Roscoe. Moreover, all ethanol extracts revealed a higher inhibition zone on S. aureus than that of E. coli. The highest antibacterial activity against S. aureus was found in ethanol extract of Alpinia galanga (L.) Willd. (8.25 mm.), while the highest antibacterial activity against E. coli was found in Alpinia officinarum Hance (2 mm.). Interestingly, the result showed a positive correlation between antioxidant activity and total phenolic content (r =0.816), between antibacterial activities against E. coli and S. Aureus (r =0.883), and between antibacterial activity against E. coli and total phenolic content (r =0.608), significantly (p-value <0.05). Therefore, Boesenbergia and Alpinia genera could be used in food and medicinal applications.
