ISOLATION OF GLYCOSIDES AND TANNINS ACTIVE COMPOUNDFROM EICHHORNIA CRASSIPES (WATER HYACINTH) AND THESTUDY OF THE ACTIVITY OF THEIR EXTRACTS AND AQUATICAND ETHANOL EXTRACT AS ANTIMICROBIALOMAR TARIQ AL-AZAWI, MOSTAFAQAHTAN AL-SMAIL, FIRAS ADNAN HUSSEINAND MOHAMAD MAHMOOD HAMADAbstract The current study aimed at isolating and extracting the glycosides and tannins compounds from the Water hyacinth plant Eichhornia crassipes (all of plant flowering and non-flowering plant above the soil), preparation of aquatic extracts for plant parts (rhizome, leaves and flowers)flowering plant and (all plant above the soil) non-flowering plant and ethanolic extracts (all plantabove the soil) flowering and non-flowering plant and testing the biological activity of the irconcentrations (25, 50, 100) mg/ml against bacteria (Staphylococcus aureus, Staphylococcusepidermidis gram positive) and (Klebsiella pneumonia, Shigella sp gram negative). The plant contains active compounds tannins, glycosides, phenols, saponins and alkaloids, and it our result that tannin extract for the flowering plant with a concentration of 100 mg/ml is most effective in inhibiting the bacterial species studied and the highest inhibition diameter was against Klebsiellapneumonia, Shigella sp gram negative average inhibition (AIZ) 13.3 and 13.3 mm respectively. |
