Klebsiella pneumoniae Extended-spectrum β-lactamase (ESBL) was one of the microorganism that cause nosocomial infection which resistant to beta-lactams antibiotics. Orange Jessamine (Murraya paniculata) was traditional medicine which believed has antibacterial components, such as: fl avonoids, alkaloids, essential oils, coumarins, terpenoids, tannins, and saponins. In the previous studies, there was antibacterial activity in ethanolic extract of Murraya paniculata againsts E.coli, K.pneumoniae, S.typhi, E.faecalis, P.aeruginosa, S.fl exneri, S.aureus, and S.sonneii with concentration 200 mg/ mL. There has not experiment about ethanolic extract of Murraya paniculata against Klebsiella pneumoniae ESBL yet. The aim of this study was to fi nd out the in vitro antibacterial activity of ethanol extracts of Murraya Paniculata against Klebsiella pneumoniae ESBL Broth dilution method with concentration 200 mg/mL, 100 mg/mL, 50 mg/mL, 25 mg/mL, 12,5 mg/mL, 6,25 mg/mL, and 3,125 mg/mL were used for the determination of the Minimal Inhibitory Concentration (MIC). While the Minimal Bacterial Concentration (MBC) was assessed using streaking method in Nutrient Agar Plate. The highest concentration in this study was obtained from 100 g of Murraya paniculata leaves dissolved in 500 mL of 40% ethanol. The study was carried out 4 times replication. At the time of the sterility test extract, germ growth appeared on Nutrient Agar Plate media, so the extract was fi ltered before being used for research. After incubation at 37 °C for 24 hours, growth of bacterial colonies on all agar plates was observed. The concentration of the ethanol extract of Murraya Paniculata (200 mg/mL) did not inhibit the growth of Klebsiella pneumoniae ESBL. The ethanol extracts of Murraya paniculata in concentration 200 mg/mL had no antibacterial activity against Klebsiella pneumoniae ESBL.

The determination of the antibacterial activity (zone of inhibition) and minimum inhibitory concentration of medicinal plants a crucial step in drug development. In this study, the antibacterial activity and minimum inhibitory concentration of the ethanol extract of Myrsine africana were determined for Escherichia coli, Bacillus cereus, Staphylococcus epidermidis and Streptococcus pneumoniae. The zones of inhibition (mm±S.E) of 500mg/ml of M. africana ethanol extract were 22.00± 0.00 for E. coli,20.33 ±0.33 for B. cereus,25.00± 0.00 for S. epidermidis and 18. 17±0.17 for S. pneumoniae. The minimum inhibitory concentration(MIC) is the minimum dose required to inhibit growth a microorganism. Upon further double dilution of the 500mg/ml of M. africana extract, MIC was obtained for each organism. The MIC for E. coli, B. cereus, S. epidermidis and S. pneumoniae were 7.81mg/ml, 7.81mg/ml, 15.63mg/ml and 15.63mg/ml respectively. Crude extracts are considered active when they inhibit microorganisms with zones of inhibition of 8mm and above. Therefore, this study has shown that the ethanol extract of M. africana can control the growth of the four organisms tested.

Oral hygiene is important to the generality of the human healthcare system. For this, the antifungal activities of the aqueous and ethanol extracts of four medicinal plants of Jatropha curcas (stem), Eucaluptus golbulus (leaves), Vernonia amygdalina (stem) and Zanthoxylum zanthoxyloides (root) were carried out in vitro against three species of Candida associated with oral thrush namely C. albicans, C. glabrata, C. tropicalis using the disc diffusion agar assay. The zones of inhibition varied with the test organisms as well as the extracts. The ethanolic extract of Jatropha curcas showed the highest zone of inhibition of 10.88 ± 0.22 mm against C. albicans while the least zone of inhibition (6.13 ± 0.13 mm) was exhibited by the ethanol extract of Z. zanthoxyloides on C. glabrata. The preliminary phytochemical screening showed the presence of tannin, saponin, alkaloids, flavonoids and reducing sugar in all plant samples. This study can be further used as a foundation for the screening of phytochemical constituents by pharmaceuticals for the control and eradication of oral thrush.

Bacterial resistance is a growing health problem worldwide that has serious economic and social impacts, compromising public health, and the therapeutic action of current antibiotics. Therefore, the search for new compounds with antimicrobial properties is relevant in modern studies, particularly against bacteria of clinical interest. In the present study, in vitro antibacterial activity of the ethanol extract and essential oil of Curcuma longa (Zingiberaceae) was evaluated against nosocomial bacteria, using the microdilution method. Escherichia coli strains, Pseudomonas aeruginosa, Klebsiella pneumoniae, Proteus sp. were used, Salmonella sp. and Bacillus sp., isolated from nosocomial infections in a hospital in the city of Monteria and reference strains of S. aureus ATCC 43300, S. aureus ATCC 29213, S. aureus ATCC 25923, P. aeruginosa ATCC 27853, E. coli ATCC 25922 and K. pneumonia ATCC 700603. The ethanol extract antibacterial profile was more efficient at higher concentrations (1 000 ppm), obtaining significant percentages of reduction of more than 50 % against K. pneumoniae ATCC 700603 and a clinical isolate of E. coli; while compared to Bacillus clinical isolate, was more active than the essential oil. For the rest of microorganisms, the reduction percentages obtained at a concentration of 1 000 ppm varied between 17 and 42 % with ethanolic extract, and 8 to 43 % with essential oil. At concentrations of 100 and 500 ppm antibacterial activity of the extracts was lower. The results indicated that the ethanolic extract and essential oil of C. longa rhizomes have active compounds with antibacterial properties that could be used in future research as a therapeutic alternative for the treatment of infections caused by nosocomial pathogens.

The objective of the present study was to explore the phytochemical profiling, antioxidant and antimicrobial activity of 50% ethanolic extract of Rosenvingea sp. found in the Bay of Bengal of Bangladesh. Seven phytochemicals were tested from the ethanolic extract of Rosenvingea, where four phytochemicals, namely steroid, glycosides, alkaloids, and tannins were present. However, ethanol extract exhibited low antioxidant activity compared to standard ascorbic acid as measured by DPPH-Free radical scavenging assay. In Brine Shrimp lethality bioassay, 50% ethanolic extract showed an LC50 value of 10.88 mg/mL, whereas positive control (K2Cr2O7) showed LC50 59.97 µg/mL suggesting the less toxic property of the ethanolic extract. In-vitro antimicrobial activity of ethanolic extract of Rosenvingea sp. was investigated against gram-positive and gram-negative bacteria species (Staphylococcus, Bacillus, Pseudomonas, Salmonella, and Klebsiella) by agar disc diffusion method. The highest antibacterial activity was noticed against Klebsiella pneumonia, Pseudomonas aeruginosa, Staphylococcus hominis with a zone of inhibition of 5.00±1.00 mm, 3.66±0.57 mm, and 3.33±0.57 mm, respectively. This is the first study on Rosenvingea sp. from the Bay of Bengal, reporting its phytochemical, antioxidant, and antimicrobial potentiality. However, more study is required to elucidate its commercial viability in the food and medicine industries. J. Bangladesh Acad. Sci. 45(1); 59-71: June 2021

Background: A snake bite is fundamentally an injury often resulting in puncture wounds meted out by the animal's fangs and occasionally resulting in envenomation. Rate of snake bites around 5,400,000 bites per year leads to over 2,500,000 envenomings and around 125,000 fatal cases annually. Snake venom enzymes are rich in metalloproteinases, phospholipaseA2, proteinases, acetylcholinesterases and hyaluronidases. Objective: Cyphostemma adenocoule is traditionally being used for the treatment of snake bites in Eritrea. The present research was aimed at evaluating the snake venom enzyme inhibition activity of C. adenocoule against puff adder venom and developing a base for the traditional use of the plant against snakebites in Eritrea. Methods: The anti-venom activity of C. adenocoule was assessed in-vitro through phospholipaseA2 enzyme inhibition assay using egg yolk as a cell. The ethanol and chloroform extracts of C. adenocoule showed in vitro anti phospholipase A2 activity, whereas the water extracts of the plant showed no activity. Results: Among the extracts of C. adenocoule, the highest percentage of inhibition was obtained from chloroform extract (95.55% at 100mg/ml). The extract showed prominent activity at different concentrations (34.7% at10mg/ml, 48.8% at 20mg/ml, 54.8% at 40mg/ml, 60.9% at 60mg/ml, 80.5% at 80mg /ml). The ethanol extract also showed certain activity at various concentrations (25.22% at10mg/ml, 14.78% at 20mg/ml, 2.6% at40mg/ml). The activity of the chloroform extracts increases as concentration increases, whereas the activity of the ethanol extracts decreases as concentration increases. The aqueous extract of C. adenocoule did not show any activity at all concentrations. Conclusion: In this study, the chloroform and ethanol extracts of the plant inhibited the enzyme of interest and thus proved the efficacy of anti-snake venom activity of the plant.

This study is aimed at determining antibacterial activity from ethanol extracts and the most active fraction of cassava leaves against clinical isolates of Staphylococcus epidermidis and Propionibacterium acnes. Research carried out by the experimental method involved determination of plants, extraction with maceration method, fractionation with liquid-liquid extraction, antibacterial activity testing of extracts and fractions by agar diffusion method, determination of most active fraction from the extract, and minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) testing of most active fraction by microdilution method. The results showed that ethanol extracts of cassava leaves had antibacterial activity against both bacteria with the most active fraction indicated by ethyl acetate. MIC values of ethyl acetate fraction against S. epidermidis were in the concentration range of 2.5%–5.0% (w/v) and against P. acnes were in the concentration range of 1.25%–2.5% (w/v). The MBC value of ethyl acetate fraction against S. epidermidis was at a concentration of 5% (w/v), while P. acnes was at a concentration of 2.5% (w/v). From the results of this study, it can be concluded that the ethanol extract of cassava leaves (Manihot esculenta Crantz) has antibacterial activity against clinical isolates of Staphylococcus epidermidis as well as on Propionibacterium acnes. The fraction with the best activity from the ethanol extract of cassava leaves to the two test bacteria was shown by ethyl acetate fraction. It is suggested that cassava leaves are possible to be developed into standardized antiacne herbal.
