Evaluation of Antibacterial Activity of <i>Prosopis Juliflora</i> (Sw.) Dc. Leaves

Abstract

Background: The ethnobotanical importance of Prosopis juliflora is well-known in the folkloric system of medicine for the treatment of various ailments. Although, the study related to the antibacterial potential of this plant, from Central India is scanty. Material and methods:The in vitro antibacterial activity of Prosopis juliflora leaves collected from the local area was evaluated against ten bacterial type cultures by agar well diffusion assay. The crude extracts prepared by two methods separately with three different solvents were examined for the preliminary antibacterial activity and phytochemical screening, the results of which were used for the choice of solvent and mass extraction of crude extract. Solvent fractionation of crude extract was done employing two sets of solvents namely Set-PCE and Set-HDB which resulted in total, six organic and two aqueous fractions, which were finally subjected to antibacterial activities. Results: Varying degrees of growth inhibition was shown by all the fractions against tested microorganisms. The highest antibacterial activity was observed in aqueous fractions as compared to solvent fractions. Conclusion: Isolation and characterization of the bioactive components can be further done by systematic screening of the most active solvent fraction which could lead to the possible source of new antibacterial agents.

In-vitro Antimicrobial Susceptibility and Phytochemical Constituents of Methanol Leaf Extract of Prosopis africana against Some Selected Microorganisms

“…[6] but different from the findings by Thakur et al [23], where tannins, saponins and terpenes were absent in methanol leaf extract of Prosopis africana. The study by Udegbunam et al [24], showed the absence of tannins in Prosopis lappacea.…”

INCLUSION OF MESQUITE POD MEAL (<i>Prosopis juliflora</i>) IN DIETS FOR NILE TILAPIA (<i>Oreochromis niloticus</i>) JUVENILES

“…Silva et al (2015), when replacing maize with mesquite meal in juvenile tilapia diets cultivated at low temperatures (20 °C), observed that the survival rate increased linearly with the inclusion levels of mesquite meal in the diet and that the presence of antinutritional factors present in small amounts in the diet would have stimulated the immune system of the fish. The presence of phytochemicals with antioxidant (Sirmah et al, 2011) and antimicrobial (Raja et al, 2012;Thakur et al, 2014) activities has already been confirmed in leaves, wood and bark of the mesquite plant. It is plausible then that the pods and seeds of the plant also contain substances with similar activities.…”

Substituição do milho pelo farelo de algaroba (Prosopis juliflora) em dietas para juvenis de tilápia do Nilo cultivados em baixa temperatura

“…Estes autores afirmam que a presença de fatores antinutricionais presentes em pequenas quantidades na dieta teriam estimulado o sistema imunológico dos peixes. A presença de fitoquímicos com atividade antioxidante (Sirmah et al, 2011) e antimicrobiana (Raja et al, 2012;Thakur et al, 2014) já foi confirmada nas folhas, na madeira e na casca da algarobeira. É plausível então que as vagens e/ou sementes da planta também possuam substâncias com atividades similares.…”
