Research Abstract

This study has aimed to find and use natural products which possess the properties to prevent food deterioration. In this research we have focused on the plant leaves which have been traditionally used to wrap foods. These plants might contain some useful properties for food preservation such as antioxidant and antimicrobial activity.
We selected promising eleven plants collected mainly in Okinawa islands based on our survey. The extracts of those leaves were examined for antioxidant activity and radical scavenging ability. Four of them showed remarkable antioxidant activity.
From YOMOGI (Artemisia princeps ), 7 polyphenols were isolated as antioxidants including dicaffeoylquinic acids. Kaempherol was isolated from KAKI (Diospyros kaki) leaves, which are used to wrap SUSHI in Yoshino, was revealed to show high antimicrobial activity against Streptocuccus mutans, a tooth-decaying bacteria. Five antimicrobial compounds were found from IRIOMOTEKUMATAKERAN (Alpinia flavellata) and determined their structures including two new distyrylcyclobutenoids. All compounds strongly inhibited the growth of Streptococcus aureus.
Our present study suggests that the constituents of the above plants could be useful for food preservation.
