56 страниц. 2011 год.
LAP Lambert Academic Publishing
The herbal juice from V. amygdalina; C.papaya and M. oleifera with ethanol and water as solvent were assessed for the antibacterial activities against Staphylococcus aureus and Escherichia coli. The chemical tests showed that the extracts have flavonoids, triterpenoids and tannins selectively. M.oleifera extract contains tannins, flavonoids and triterpenes in ethanol but only triterpenes in water. V.amygdalina extract contains more triterpenes and flavonoids in ethanol. C.papaya in ethanol shows flavonoids, triterpenes; and tannins and triterpenes in water extracts. Sensory judgment however, showed desirable colors to all the extracts ; strong and weak odors for ethanol and water extracts respectively, and possessing oily for ethanol extracts, appearance was very good, good and moderately good for M.oleifera, V.amygdalina, C.papaya respectively, while not appealing for their water extracts.
