The Effect of Butterfly Pea (Clitoria ternatea) Against Fish Pathogens: A Mini-review

Abstract

Butterfly pea (Clitoria ternatea) is a plant with the potentiality to inhibit the fish pathogens because its rich of bioactive compounds. Leaves, stems, roots and flowers contain diverse substances among which there are alkaloids, tannins, glycosides, terpenoids, phenols, reducing sugars, flavonoids etc. The secondary metabolites in leaves reported can inhibit the pathogens such as Aeromonas formicans, Aeromonas hydrophilia, Streptococcus agalactiae, Escherichia coli, Klebsiella pneumoniae, Bacillus subtilis. The roots can inhibit Pseudomonas aeruginosa and K. pneumoniae. The bioactive compounds in flowers and seeds can inhibit B. subtilis, E. coli, P. aeruginosa, Klebsiella spp. Different part of plant give different effect to inhibit the growth of pathogens because it contains different types and levels of secondary metabolites. In addition, the different solvent used in extraction process give difference result to prevent the growth of disease microorganism in fish with the inhibition zone ranged 7-28 mm.
