Antimicrobial and antioxidant activities of Mimosaceae plants; Acacia modesta Wall (Phulai), Prosopis cineraria (Linn.) and Prosopis juliflora (Swartz)

Abstract

Antimicrobial and antioxidant activities of Mimosaceae plants; Acacia modesta Wall (Phulai), Prosopis cineraria (Linn.) and Prosopis juliflora (Swartz) In the present study the methanolic leaf extracts of three plant species of family Mimosaceae viz., Acacia modesta Wall (Phulai), Prosopis cineraria (Linn.) Druce and Prosopis juliflora (Swartz) DC. were used to evaluate their antibacterial antifungal and antioxidant activity. Simple maceration method was used for the preparation of plant extracts. The extracts were tested against four strains of bacteria (Bacillus subtilis, Escherichia coli, Vibrio cholera and Enterobacter aerogenes) and two strains of fungi (Aspergillus niger and Aspergillus fumigatus). At 15 mg/ml extract concentration the maximum inhibitory zones observed in Acacia modesta, P. cineraria and P. juliflora were 20, 18 and 25 mm, respectively. P . cineraria gave best response against A. niger and A. fumigatus by producing 15.38 and 8% inhibition, respectively. P. juliflora showed 7.69% inhibition against A. niger. While A. modesta showed 11.53% activity against A. niger and 0.8% against A. fumigatus. The Antioxidant activities of these medicinal plants also showed significant results. Maximum radical scavenging activity (%RSA) was observed in P. cineraria and P. juliflora, that is, 60.48 and 47.82%, respectively, as compared to A. modesta which gave minimum %RSA value of 41.42%.

In-vitro Evaluation of Anti-Bacterial, Anti-biofilm and Cytotoxic Activity of Naturally Inspired Juglans regia, Tamarix aphylla L., and Acacia modesta with Medicinal Potentialities

“…The ethanolic extract of T. aphyla showed remarkable activity against sixteen Gram-positive and Gram -negative bacterial strains. As compared to the standard drug, the highly significant activity of Acacia modesta and other medicinal plants extracts was recorded by Napar et al 15 against S. aureus, B. subtilis and E. coli. The stem extracts of A. modesta with five bacterial strains showed that this specific part of the plant has profound antibacterial activity, and same results were noted by 17 .…”

“…The dried bark of this tree is conventionally used in Pakistan for improving oral hygiene and promoting teeth brightening. Earlier studies reported the antimicrobial activity of this plant against bacteria and fungi that may be due to the presence of polyphenols 1,2,[9][10][11][12][13][14][15] .…”

“…Hemolytic activity of plant extracts was conducted by following the method used by 15 . Briefly, freshly collected human blood (3 mL) was gently mixed in heparinized tubes (to avoid coagulation) and transferred into a sterile Falcon tube (15 mL) followed by centrifugation for 5 min at 850 g. The supernatant was decanted, and RBCs were washed thrice with chilled sterile PBS solution.…”

Evaluación fenólica y antioxidante en madera de Prosopis laevigata y corteza de Acrocarpus fraxinifolius

“…En la corteza de Prosopis Juliflora se encontró una correlación entre la concentración de un extracto y la inhibición de radicales libres de DPPH (Siahpoosh y Mehrpeyma, 2014). Otros extractos de especies de Prosopis han mostrado capacidad antioxidante, como los extractos metanólicos de hojas de P. cineraria y P. juliflora (Napar et al, 2012). Poudineh et al (2015) evaluaron el efecto de los solventes etanol, metanol, octanol y n-heptano sobre las actividades antioxidantes y antibacterianas de los extractos de semillas y vainas de P. farcta, el mayor contenido fenólico y la mayor actividad se obtuvo al utilizar octanol como solvente de extracción.…”

Thermal Evaluation, Rheological Properties and Characterization of Pristine, Modified and Polyacrylamide-Mediated Grafted Acacia modesta Gum

“…Gum acacia is a complex polysaccharide exudate, that is obtained from the trees of Acacia species, this exudate protects the tree against the external attacks 14 . Antimicrobial potential of extracts of leaves and stem has also been estimated that leads to use of young twigs of this plant as tooth stick (miswak) 15,16 . Hepatoprotective potential of A. modesta (Bark extract) has also been reported in plasma proteins level and serum levels of hepatic metabolic enzymes were used for the analysis of hepatotoxicity 17 .…”
