Screening antifungal activities of selected medicinal plants

Abstract To prevent foodborne diseases and extend shelf-life, antimicrobial agents may be used in food to inhibit the growth of undesired microorganisms. The present study was aimed to determine the antimicrobial and antifungal activities of the fermented medicinal plants extract using Lactobacillus acidophilus ATCC 4356. The fermentation kinetic parameters, biochemical composition and the volatile compounds of the fermented plant extract was assessed. The results showed that, the fermented plants beverage exhibited high content in polyphenols, flavonoids, and tannins (152.7 mg AGE/ L; 93.6 mg RE/ L; and 62.1mg CE/ L, respectively) to compare with the extract without fermentation. The GC-MS headspace analyses showed the presence of twenty-four interesting volatile compounds. The richness of the fermented plants extracts of polyphenols content and the bioactive compound such as Eucalyptol, Camphene, α-Phellandrene, α-Terpinene improve their biological activity. In addition, the fermented plants extract exhibited a high antimicrobial potential against resistance pathogenic bacteria and fungi determined by different methods. The maximum inhibition showed in the fermented plants beverage against Escherichia coli 25922/3, Pseudomonas aeruginosa 27853 ATCC, Staphylococcus aureus 29213 ATCC, Enterococcus aerogenes 13048 ATCC, Phytophthora infestans P3 4/91 R+, Phytophthora infestans P4 20/01 R, Phytophthora infestans (GL-1). The obtained results support the hypothesis of using whey as a functional ingredient to improve food preservation. The bioprocesses of fermentation technology enhance antimicrobial and antifungal activities which could be used in different industrial applications.

Bixa orellana, Jatropha curcas and Cassia alata are three of the prominent plants used for traditional medicine in Nigeria. Dermatophytosis also known as tinea or ringworm is the most frequent superficial fungal infections in Nigeria. Objective: In this Present Study, We Aimed at Comparing The Phytochemical Components and the Antifungal Efficacy of these Medicinal against Selected Dermatophytes. Study Design: Cross Sectional Study among a Particular Population. Place and Duration of Study: Department of Microbiology, Federal University of Technology, Akure, Ondo State. Between March 2019 and September 2019. Methods: The phytochemical contents of the plants were determined and the in-vitro antifungal activities of Bixa orellana, Jatropha curcas and Cassia alata were screened against seven species of Trichophyton (T. ajelloi, T. mentagrophytes, T. rubrum, M.gypseum T. soudenensis, T. tonsurans and T. verrucosum) using agar dilution method. Results: The phytochemical screening revealed the presence of flavonoid, saponin, phenol, steroids, glycoside, phytosteroids, alkaloids, terpenoid, tannin, and cardiac glycoside in various quantities. The findings from our study showed that the ethanol extracts of these medicinal plants have more antifungal activities than other solvents. However, the hexane and ethanol extracts of Jatropha curcas was observed to be significantly higher than other extracts. The zone of inhibition recorded ranges from 22 mm-32 mm and the minimum inhibitory concentration (MIC) of 12.5 mg/ml was recorded. Conclusion: The ethanolic extract of Jatropha curcas showed broad effectiveness against the tested pathogens when compared to other plants and we conclude that the plants antifungal property is concentration dependent. However, we recommend further studies on these plants extracts using a large number of different isolates and solvents.

Antibacterial And Antifungal

Background: Podoconiosis and lymphatic filariasis are the most common causes of lower limb lymphoedema in the tropics. Many sufferers experience frequent painful episodes of acute bacterial infection. Plant based traditional medicines are used to treat infections in many countries and are culturally established in Ethiopia. Ethiopian medicinal plants found to have antibacterial and antifungal activities were reviewed with the aim of increasing information about the treatment of wound infections in patients with lymphoedema.Methods: This study collates data from published articles on medicinal plants with antibacterial and antifungal activities in Ethiopia. A systematic search of Scopus, EMBASE, PUBMED/MEDLINE and Google Scholar was undertaken. The Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines were followed. The protocol was registered on PROSPERO with registration number CRD42019127471. All controlled studies of in vitro antibacterial and antifungal activities were considered. All articles containing the descriptors published until June 28, 2019 were included. The outcome was measured as percent inhibition of microbial growth. For quality assessment of individual in vitro studies, OECD guidelines and the WHO-Good Laboratory Practice (GLP) handbook were used.Results: Seventy-nine studies met the inclusion criteria. A total of 150 plant species and three compounds had been tested against 42 species of bacteria, while 43 plant species had been tested against 22 species of fungus.Conclusion: Materials derived from several Ethiopian medicinal plants have been shown to have promising activity against a variety of bacteria and fungi. Those derived from Azadiractha indica A. Juss. and Lawsonia inerms L. are the most extensively studied against a wide range of gram-negative and positive bacteria, and fungal species.

Allanblackia Gabonensis

Background: Biological activities of medicinal plants make them attractive alternative complementary medicines. Therefore, this study aimed to assess the antioxidant and antifungal activities of the methanol extract of Myrianthus arboreus, Allanblackia gabonensis, Gladiolus quartinianus, Peperomia fernandopoiana and Vepris soyauxii. Methods: Total phenolic contents (TPC) and flavonoid contents (FC) were evaluated using standard methods. The antioxidant activity of the extracts was determined by 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging and ferric reducing power assays. Antifungal activity was evaluated by the broth micro-dilution method. Results: TPC of extracts ranging from 67.89 to 196.01 mgGAE/g TPC were very higher in P. fernandopoiana whole plant (PFW) extract (196.01±10.25 mgGAE/g) and MAL (165.71±10.68 mgGAE/g) whereas the A. gabonensis fruit extract (AGF) and M. arboreus bark extract (MAB) had the highest flavonoid content (66.54 ± 2.12 and 48.13 ± 1.65 mgEC/g of extract, respectively). Apart from M. arboreus leave extract (MAL), all extracts showed important DPPH radical scavenging activity (IC50 < 20 μg/mL). AGFl and PFW exhibited significant ferric reducing power compared to ascorbic acid and other extracts (P<0.05). Each of the tested extracts showed antifungal activity against atleast one of the five pathogenic fungi, with MICs ranging from 128 to 1024 µg/mL. MAL was active on all the tested fungi whereas MAB showed the highest antifungal activity (MIC=128 µg/mL). Conclusion: The findings of this study emphasize the evidence that the methanol extracts of the leave and bark of Myrianthus arboreus could be an alternative to fight against oxidative stresses and infections due to opportunistic yeast pathogens. Keywords: Oxidative stress; fungal infection; medicinal plant; antioxidant activity; antifungal activity.
