Description 294-298
Antimicrobial activity
of the methanolic extract and fractions of Lumnitzera racemosa was
evaluated against fungi, virus and pathogenic bacteria. Crude methanolic
extract and n-butanol fraction were ineffective against fungi and virus tested
but exhibited significant bactericidal activity on all the bacteria tested.
Flavonoids, quercetin and myricetin are the main active constituents with
quercitrin, quercetin-3O-hexoside, kaempferol 4′-methyl ether,
kaempferol-3,4′dimethyl ether, and bi-isorhamnetin and
myricetin-7O-methylether(3→8″)quercetin –3O-rhamnoside, which are also
constituents of the active fraction being partly responsible for the observed
activity. Myricetin showed the most potent activity
(MIC – 1.5 mg/ml) against Pseudomonas aeruginosa being markedly
active against others (MIC – 6 mg/ml). Based on the current findings it can be
concluded that this plant has antibacterial activity.
