|
This study investigated the physiological activities and antimicrobial effects of sesame, black sesame, perilla and olive oil extracts. Total flavonoid contents of sesame, black sesame, perilla and olive oil extracts were 2.7, 1.9, 3.0 and 1.4%, respectively, while total phenol contents were 6.5, 4.5, 4.1 and 10.1%, respectively. The electron donating abilities of sesame oil extract were markedly higher than black sesame, perilla or olive oil extract (p＜0.05). The SOD-like activities of black sesame, perilla and olive oil extracts were 67.2%, 90.2% and 46.7%, respectively; in contrast, sesame oil extract did not show SOD-like activity. The order of the nitrite-scavenging abilities of sesame, black sesame, perilla and olive oil extracts was sesame＞black sesame＞perilla＞olive oil extract (p＜0.05). Olive oil extract showed strong antimicrobial activity to Bacillus cereus, Micrococcus luteus, Escherichia coli and Salmonella Enteritidis. The black sesame oil extract showed weak antimicrobial activity to Micrococcus luteus and Escherichia coli; conversely, sesame and perilla oil extracts did not show any antimicrobial activity.
