Chemical composition and antibacterial property of Eclipta prostrata (L.) L.

Eclipta prostrata (L.) L. belonging to the Astearaceae family has been long used worldwide by various communities as a traditional medicine. We studied antibacterial activity of different extracts from against Aeromonas hydrophila, dhakensis, and Vibrio parahaemolyticus . The processing this extract using repeated column thin layer chromatographic techniques resulted in isolation three compounds including luteolin (1), kaempferol (2), kaempferol-3-O-α-L-rhamnopyranoside (3), which were identified NMR. Among them, kaempfreol-3-O-α-L-rhamnopyranoside was isolated for first time shows good hydrophila is major pathogen aquaculture industry. results demonstrate beneficial effects E. an antimicrobial bioactive compound medicinal usages.
