Evaluation of the Antibacterial and antifungal activity of Ipomea hederacea
ABSTRACT In the present scenario, antimicrobial resistance is a major problem in the treatment of Infections. Hence the search for an Ideal anti -microbial continues in the plant kingdom. Plants have always been a rich source of antimicrobials: turmeric, and tulsi to name a few. Several Ipomoea species have been found to possess antimicrobial properties. The purpose of the present study is to evaluate the antibacterial and antifungal activities of the hydro alcoholic extract (70%alcohol in water) of its Arial parts of one such species, Ipomoea hederacea (Ivy leaf morning glory) by determination of the zone of inhibition by the cup plate method. It was found that Ipomoea hederacea (IPO) exhibited moderately significant antifungal activities against Candida albicans, Aspergillus niger, Aspergillus oryzae, Penicillium chrysogenum and, antibacterial activity against both gram positive bacteria, that is, Gram Positive bacteria -Staphylococcus aureus, Bacillus subtilis Gram Negative bacteria- Proteus vulgaris, Escherichia coli, Klebsiella pneumonia, Pseudomonas aeruginosa, as compared to that of the standard.

pomoea nil (Linn) Roth, (morning glory / kaladanah; Convolvulaceae), is frequently grown in gardens and lawns for its ornamental flowers and often runs wild in hedges and wastelands. Plant is documented to possess beneficial effect in erectile dysfunction, impotence and also have antispasmodic, bronchodilator, blood purifier, diuretics, astringent, anti-inflammatory and hepato-protective etc. In this study, disc diffusion method was adopted to evaluate and compare the antimicrobial activity of the aqueous and organic (DCM, ethanol, methanol) extracts of the seeds and whole plant (leaves, flower and bark) of Ipomoea nil, in order to know the best extract and plant part having the beneficial activity against pathogenic bacteria species of both G +ve strains, i.e., Staphylococcus aureus, Bacillus pumilus, Streptococcus pneumoniae, G -ve strains, i.e., Escherichia coli, Citrobacter freundii and Klebsiella pneumoniae and two species of fungi (Candida albicans, Aspergillus niger). Methanolic and ethanolic extract of the seeds of the Ipomoea nil showed significant antibacterial activity against Staphylococcus aureus (G +ve) having the relative percentage of inhibition of 89.88 % and 85.67 % respectively, while methanolic extract of the whole plant also have relative percentage of inhibition of 83.96%, whereas ethanolic extract of the whole plant have good antibacterial activity. Aqueous and DCM extract of seeds and whole plant showed weak inhibitory response. Modified agar well diffusion method was adopted to measure the minimum inhibitory concentration (MIC) and MIC values for G +ve, lies within the range of 30 to 60 μg /ml (seeds), 60 to 90 μg /ml (whole plant) and for the Gram -ve, it lies within the range of 90 to 250 μg /ml (seeds), 180 to 500 μg /ml (whole plant) and for the fungi, it varies from 500 to 2000 μg /ml. Present study clearly indicate that the antimicrobial activity varies from part to part and the plant material used and it also indicate that the methanolic extract of Ipomoea nil is a potentially good candidate for the therapy of antibacterial-resistant bacteria and would therefore require further study.

The aim of the present study was to investigate the antibacterial activity of chloroform, ethyl acetate, hexane and methanol extracts of Ipomoea pes-caprae(Linn.) R. Br. extracts of roots and stem of plant Ipomoea pes-caprae(Linn.) R. Br. The extracts were tested against different clinical bacterial isolates and the antibacterial activity was performed by using well-plate method. The results demonstrated that the methanol extract of Ipomoea pes-caprae stem and ethyl acetate extract of Ipomoea pes-caprae root exhibit strong antibacterial activity. Our results showed that this plant have observable therapeutic effects on potential infectious agents and can be used as an alternate to conventional medicines.
Antimicrobial Activity of Ipomea Carnea Leaves
Asian Journal of Microbiology Biotechnology and Environmental Sciences, 2022
Bioprospecting is a systematic and organized search for useful natural products derived from bioresources including plants, animals and microorganisms. These are potential sources of novel chemical and biological products for medicine, agriculture, and other industries. The aim of this work was to check bioprospecting of Ipomoea carnea Jacq plant. Extract of Ipomoea carnea Jacq plant was searched for novel therapeutic compounds. Its extract was used to kill the pest, weeds and unwanted plants. It also preserves soil fertility and helps in bio composting and anti-microbial agent. Ipomoea carnea plant has positive and negative effects on antimicrobial properties, crude ethanol extract elucidate prominent antimicrobial activity against Pseudomonous auroginosa and Bacillus subtilis

Abstract Research on antimicrobial and anti-oxidant activity from plant sources is increasing due to positive effects on human health. However relatively little work has been done to investigate the antimicrobial and antioxidant effects of methanolic extracts from Ipomoea hederacea. In the present study methanolic extracts of leaves, flowers, stem, seed and roots from Ipomoea hederacea were evaluated using an antimicrobial assay, the determination of total phenolic content, 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical and the total antioxidant capacity. Our results suggested that methanolic extracts exhibited high antimicrobial effects when tested against various bacterial and fungal strains (i.e. B. subtilis, P. multocida, S. aureus, E. coli, A. niger, A. flavus, A. alternate and R. solani). The total phenolic content showed the highest value for stem extract (131.11±1.22 mg/g), and the lowest for root extract (74.44±1.52 mg/g). The tested extracts were able to reduce the stab...
In vitro studies of antibacterial and antioxidant activity of Ipomoea pes-caprae root extracts
To evaluate the antibacterial and antioxidant activity of Ipomoea pes-caprae root (belonging to the family of Convolvulaceae) was studied in five different solvents. Antibacterial activity was determined using well diffusion assay for eight strains of bacteria. Minimum inhibitory concentrations were determined in eight bacterial strains by agar well diffusion assay. Other focuses included the determination of antioxidant activity using DPPH assay and IC50 (Inhibitory concentration) values were also determined using broth dilution assay. Preliminary phytochemical screening of the crude extracts revealed the presence of alkaloids, flavonoids, tannins, saponins and phenolics. The presence of these bioactive constituents is associated with the antibacterial activity of the plant. Methanol extracts of I.pes-caprae exhibited highest inhibition zone of 17mm, 18mm and 21mm against Klebsiella pnemoniae, Escherichia coli, and Bacillus subtills. During DPPH assay of methanol extract of I.pes-caprae root shows highest antioxidant activity of 92.04% in 200(µg/ml). The results confirm that I.pes-capra roots can be used as source of drugs to fight infections caused by susceptible bacteria.
Phytochemical and Antibacterial Properties of Leaf Extracts of Ipomoea asarifolia
Phytochemical and antibacterial properties of ethanolic extract of the seeds of African Star Apple (Chrysophyllum albidum) were investigated. The phytochemical result revealed the presence of saponins, carbohydrates, flavonoids, quinones, cardiac glycosides, fatty acids and terpenoids. The antibacterial activity was studied using agar well diffusion method at different concentrations against six pathogenic bacterial strains, three Gram-positive (Staphylococcus aureus, Micrococcus varians and Bacillus cereus) and three Gram-negative (Escherichia coli, Pseudomonas aeruginosa and Proteus vulgaris). Significant inhibitory activities were exhibited by the ethanolic seed extracts for all test organisms except Bacillus cereus. Zone of inhibition of the crude ethanolic extract was correlated with that of a standard antibiotic Gentamicin, for antibacterial activity. The results indicated a notable inhibition of the bacterial growth.

D glucoside), H-2 (22, 23-dihydro-"-spinosteryl glucoside) & CH-2 (salicylic acid) isolated from the chloroform extract of stem of Ipomoea turpethum and the crude petroleum ether, chloroform and ethyl acetate extracts were screened against thirteen pathogenic bacteria for their antibacterial activities. The minimum inhibitory concentration (MIC) of the isolated compound CH-2 was also measured against Bacillus subtilis, Shigella dysenteriae, Sarcina lutea and Escherichia coli. The values were found to be between 128 and 256 µg/ml. The cytotoxic activity of CH-2 and chloroform and ethyl acetate extracts was also measured by brine shrimp lethality bioassay and the LC values were found 50
