Antivibrio activity of Cryptocoryne elliptica culture

Abstract

This research was conducted on an aquatic plant, Cryptocoryne elliptica that grow through in-vitro culture. The main purpose of this research was to investigate antivibrio activity of methanol and aqueous extracts of C.elliptica. Beside that, the minimal inhibitory concentration (MIC) of extracts for antivibrio and the age of plant with highest antivibrio were determined. The grinded dried leaves and petioles with 30, 50 and 70 cultivation days were used in extraction. The antivibrio activity was evaluated using Kirby-Bauer method against Vibrio alginolyticus, Vibrio parahaemolyticus and Vibrio vulnificus. The 500µg/ml of extracts concentration were resulted in negative reaction of antivibrio activity with absence of inhibition zones to all 30,50 and 70 cultivation days of plant extracts. Overally, the result showed of the low antivibrio compound produce by in­ vitro plantlet of C.elliptica. Through this research suggesting that, C.elliptica is not suitable as a good control toward Vibrio spp.
