Search for New Antioxidants and Other Related Bioactive Compounds from Zingiberaceous Species

Thirty-one species from Zingiberacea family were screened for their antioxidant (FTC method), antimicrobial (disc diffusion method), and antitumour promoting (EBV EA assay method) activities. Three species, A lpinia zerumbet, A lpinia rfflesiana and Etlingera elatiar, were selected for further s...
