Abstract

The aims of this research were (1) to study the antimicrobial activity of 25 species in five families of Thai medicinal plants which affect six important food microorganisms consisting of Bacillus cereus TISTR687, Escherichia coli TISTR780, Salmonella Typhimurium TISTR292, Pseudomonas aeruginosa TISTR781, Staphylococcus aureus TISTR118 and Candida albicans TISTR5779; and (2) to study free radical scavenging activity. The crude extracts from 25 species in five families had only one family from the Caesalpiniaceae family, which included Caesalpinia sappan L., Cassia. timoriensis DC., Cas. siamea Lam. and Senna garrettiana Graib. It displayed remarkable antimicrobial activity, especially on B. cereus and Staph. aureus, while other families crude extracts showed antimicrobial activity in some species and were specific in some microorganisms. When testing preliminary free radical scavenging activity, it was found that almost all the crude extracts of 25 species in five families had activity, except Eclipta prostrata Linn., Artemisia vulgaris Linn. and Bridelia ovata Decne.
