The phytochemical screening exhibited that the extracts were enriched with the existence of alkaloid, steroids, phenols, terpenoids, flavonoids, saponin, quinones, coumarins etc. Presence of phytochemicals varied from plant to plant. Quantitative analysis of phenolics revealed that Melastoma malabathricum contained maximum phenolics compound counting 76.29 mg/g gallic acid equivalent (GAE) of dry leaves powder. Total flavonoids content was found to be highest in Ricinus communis extract amounting 23.23mg/g quercetin equivalent(QE) of dry leaves powder. Mimosa pudica and Melastoma malabathricum extract possessed the highest free radical scavenging activity against DPPH. IC50 values, obtained by DPPH activity, was very high in Heliotropium indicum (228.58µg/ml). In contrast, lowest value of IC50 was found in Mimosa pudica (32.46µg/ml) which was followed by Melastoma malabathricum (48.90 µg/ml) and Ricinus communis (54.84µg/ml). IC50 values were shown inversely proportional to the free radical scavenging activity. Furthermore, antibacterial activities of methanolic extracts of selected plant’s leaves were analyzed against five clinically significant organisms (Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Salmonella sp, Staphylococcus aureus). Comparing six medicinal plants, the crude extract of Melastoma melabathricum and Solanum torvum exhibited potent antibacterial activity against all studied bacterial strains (11-16.75 mm zone of inhibition). Other four medicinal plant’s extracts showed antibacterial activity against different bacterial strains. To broaden this study, further in vivo models are essential for proving the effectiveness of leaves as candidate drug.

medicinal plants such as Melastoma malabathricum, Mimosa pudica, Ricinus communis, Solanum torvum, Alocasia macrorrhiza were employed to investigate the presence of various phytochemicals using different biochemical tests, to determine total phenolic content based on Folin-Ciocaltaeus reagent method, total flavonoid contents using aluminium chloride colorimetric method, antioxidant potentiality according to DPPH assay and antibacterial efficacy by disc diffusion assay of the selected medicinal plants. The phytochemical screening exhibited that the extracts were enriched with the existence of alkaloid, steroids, phenols, terpenoids, flavonoids, saponin, quinones, coumarins etc. Presence of phytochemicals varied from plant to plant. Quantitative analysis of phenolics revealed that Melastoma malabathricum contained maximum phenolics compound counting 76.29 mg/g gallic acid equivalent (GAE) of dry leaves powder. Total flavonoids content was found to be highest in Ricinus communis extract amounting 23.23mg/g quercetin equivalent(QE) of dry leaves powder. Mimosa pudica and Melastoma malabathricum extract possessed the highest free radical scavenging activity against DPPH. IC50 values, obtained by DPPH activity, was very high in Heliotropium indicum (228.58µg/ml). In contrast, lowest value of IC50 was found in Mimosa pudica (32.46µg/ml) which was followed by Melastoma malabathricum (48.90 µg/ml) and Ricinus communis (54.84µg/ml). IC50 values were shown inversely proportional to the free radical scavenging activity. Furthermore, antibacterial activities of methanolic extracts of selected plant’s leaves were analyzed against five clinically significant organisms (Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Salmonella sp, Staphylococcus aureus). Comparing six medicinal plants, the crude extract of Melastoma melabathricum and Solanum torvum exhibited potent antibacterial activity against all studied bacterial strains (11-16.75 mm zone of inhibition). Other four medicinal plant’s extracts showed antibacterial activity against different bacterial strains. To broaden this study, further in vivo models are essential for proving the effectiveness of leaves as candidate drug.

Mirza, Phytochemical analysis and comprehensive evaluation of antimicrobial and antioxidant properties of 61 medicinal plant species, Arabian Journal of Chemistry (2015), doi: http://dx.Abstract Plants are rich source of therapeutic compounds that have tremendous applications in pharmaceutical industry. To find new sources of antimicrobial and antioxidant agents, methanol/chloroform and aqueous extracts of 61 medicinal plants were evaluated systematically. Antimicrobial activity was assessed against six bacterial and five fungal strains, while natural antioxidants were studied by using reducing power (RP), total antioxidant capacity (TAC) and 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging assay. Six plants exhibited broad spectrum antibacterial activity while two exerted significant antifungal activity. Total phenolic content (TPC) of the samples varied from 20.2 -85.6 mg /g dry weight (DW) in M/C extracts and 5.5 -62.1 mg /g DW in aq. extracts, expressed as gallic acid equivalents (GAE). Total flavonoid content (TFC) varied from 2.9 -44.5 mg quercitin equivalent (QE) /g DW of sample 2 for M/C extracts and 2.4 -37.1 mg QE /g DW for aq. extracts. The results showed that antioxidant activities of plant species varied to a great extent not only among extracts (M/C and aq.) but also between the assays used for antioxidant evaluation. Significant linear correlation (p &lt; 0.01) of TPC with antioxidant activities suggested their contribution to antioxidant activity. Using high performance liquid chromatography coupled with diode array detector (HPLC-DAD), gallic acid and rutin were detected in most of plant extracts with significant antioxidant activities. Study identifies plants with antimicrobial and antioxidant properties which could be used for isolation of desired therapeutic compounds and to develop infusions, nutriceuticals and pharmaceuticals. Samples of 61 medicinal plants were collected from different areas of Pakistan and identified by Professor Dr. Rizwana Aleem Qureshi, Department of Plant Sciences, Quaid-i-Azam University, Islamabad. Voucher specimens were submitted to the herbarium of Quaid-i-Azam University for future reference. The plants were selected on the basis of local use of these plants in folk medicine.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{&quot;location&quot;:&quot;wsj-grid-card-download-pdf-modal&quot;,&quot;work_title&quot;:&quot;Phytochemical analysis and comprehensive evaluation of antimicrobial and antioxidant properties of 61 medicinal plant species&quot;,&quot;attachmentId&quot;:42367932,&quot;attachmentType&quot;:&quot;pdf&quot;,&quot;work_url&quot;:&quot;https://www.academia.edu/20820749/Phytochemical_analysis_and_comprehensive_evaluation_of_antimicrobial_and_antioxidant_properties_of_61_medicinal_plant_species&quot;,&quot;alternativeTracking&quot;:true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/20820749/Phytochemical_analysis_and_comprehensive_evaluation_of_antimicrobial_and_antioxidant_properties_of_61_medicinal_plant_species"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="3" data-entity-id="64925122" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/64925122/Antimicrobial_Antioxidant_Activities_in_vitro_and_Polyphenol_Contents_of_the_Leaf_Extract_of_a_Versatile_Medicinal_Plant">Antimicrobial, Antioxidant Activities in vitro and Polyphenol Contents of the Leaf Extract of a Versatile Medicinal Plant</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="62657577" href="https://ufs.academia.edu/KazeemAlayande">Kazeem Alayande</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Asian Journal of Applied Sciences, 2017</p><p class="ds-related-work--abstract ds2-5-body-sm">This study assessed polyphenolic contents, antioxidant and antimicrobial activities of the solvent fractions obtained from Combretum racemosum leaf extract.

So, this study aimed to carry out the antibacterial and antioxidant activity of two medicinal plants which are used traditionally for wound healing activity, i.e.,Mimosa rubicaulis and Reinwardtia indica. Different parts of Mimosa rubicaulis (root, stem, and leaves) and Reinwardtia indica (flower and leaves) were used for the study. Extractions were done by maceration using ethanol as solvent. Antibacterial activity was carried out by the well diffusion method, and antioxidant activities were screened by DPPH radical scavenging and NO scavenging assays. Extract of M. rubicaulis has shown a weak zone of inhibition towards S. aureus and P. vulgaris whereas R. indica has shown no zone of inhibition towards selected bacterial strains. Leaf, root, and stem extracts of M. rubicaulis have shown potent antioxidant activity, i.e., IC 50 value of 9.8 µg/ml, 10.19 µg/ml, and, 13.64 µg/ml, respectively. Similarly, leaf extract of R. indica exhibited antioxidant activity with an IC 50 value of 19.73 μg/ml. e percentage inhibition of NO radicals of root and stem of M. rubicaulis and leaves of R. indica was 31%, 21%, and 22%, respectively. Out of these two plant species, M. rubicaulis had shown antibacterial activity towards selected microorganism, but antioxidant activity was shown by both plant species. ese properties on above mentioned two plant species might help for the development of a marketed formulation for antibacterial and wound-healing agent since wound healing is promoted by antibacterial and antioxidant activities.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{&quot;location&quot;:&quot;wsj-grid-card-download-pdf-modal&quot;,&quot;work_title&quot;:&quot;Evaluation of the Antibacterial and Antioxidant Activity of Mimosa rubicaulis and Reinwardtia indica&quot;,&quot;attachmentId&quot;:113220397,&quot;attachmentType&quot;:&quot;pdf&quot;,&quot;work_url&quot;:&quot;https://www.academia.edu/117338143/Evaluation_of_the_Antibacterial_and_Antioxidant_Activity_of_Mimosa_rubicaulis_and_Reinwardtia_indica&quot;,&quot;alternativeTracking&quot;:true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/117338143/Evaluation_of_the_Antibacterial_and_Antioxidant_Activity_of_Mimosa_rubicaulis_and_Reinwardtia_indica"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="9" data-entity-id="52069029" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/52069029/Determination_of_antibacterial_and_antioxidant_potential_of_some_medicinal_plants_from_Saurashtra_Region_India">Determination of antibacterial and antioxidant potential of some medicinal plants from Saurashtra Region, India</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="183658879" href="https://independent.academia.edu/JayaLakshmi346">Jaya Lakshmi</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Indian journal of …, 2009</p><p class="ds-related-work--abstract ds2-5-body-sm">Many plants used in Saurashtra folk medicine have been reported to exhibit high antibacterial and antioxidant activities. In the present study, some parts of five plants, Guazuma ulmifolia L., Manilkara zapota L., Melia azedarach L., Syzygium cumini L. and Wrightia tomentosa R.&amp; S., were evaluated for their antibacterial activity, total phenol content, flavonoid content, 2,2-diphenyl-1-picrylhydrazyl free radical scavenging activity and phytochemical analysis, using successive extraction by cold percolation method with petroleum ether, ethyl acetate, methanol and water. In vitro antibacterial activity was evaluated against five bacterial strains viz. Bacillus subtilis, Staphylococcus aureus, Pseudomonas aeruginosa, Salmonella typhimurium and Enterobacter aerogenes by agar well diffusion method. Among the plants screened, W. tomentosa leaf and fruit showed the best antibacterial activity. The Gram-positive bacteria were more susceptible than Gram-negative bacteria.
