Endophytes or endophytic fungi have been investigated as a store house of bioactive compound. This study was aimed to evaluate the potential antibacterial activity of endophytic fungi isolated from Medinilla speciosa Blume. The antibacterial test was determined by measuring the inhibition zone with disk-diffusion method. Twenty endophytes were isolated from the leaves of Medinilla speciosa Blume and identified morphologically. The results demonstrated that ten isolates showed variation in their antibacterial activity against Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 25923, Bacillus subtilis ATCC 6633, and Shigella dysenteriae ATCC 13313. Further investigation will be needed to explore and identify the bioactive molecules of the isolated endophytic fungi.

Context: Plant materials contain glycoproteins (phytolectins) that are toxic in nature may play a key role in the control of various normal and pathological processes in living organisms and have diverse biochemical and diagnostic applications. Objectives: Screening of three lectins SLL-1, SLL-2 and SLL-3 purified from Drumstick (Moringa oleifera Lam.) leaves for their antibacterial activities and brine shrimp lethality bioassay. Materials and Methods: Three bioactive lectins were purified from Drumstick leaves by conventional chromatographic methods. The lectins were tested for their antibacterial activities against three pathogenic bacteria- Escherichia coli (gram-negative) Shigella dysenteriae (gram-negative) and Staphylococcus aureus (gram-positive) using the standard disc-diffusion method. Mortality of the brine shrimp naupli was assessed by hality bioassay. Results: All the lectins showed antibacterial activity against E. coli, Sh. dysenteriae and St. aureus. They also showed cytotoxic effect in brine shrimp (Artemia salina L.) lethality bioassay. The LC50 values of SLL-1, SLL-2 and SLL-3 were found to be 15.8, 17.78 and 14.12 μg/ml respectively. The experimental results revealed that SLL-3 is more cytotoxic than other lectins. The lectin SLL-3 showed lowest activity whereas SLL-1 showed highest activity against the three bacteria. Conclusion: Results suggest that the extracts from M. oleifera leaf can be a source of natural antimicrobials with potential applications in pharmaceutical industry to control coliform bacteria.Key words:  Drumstick; Moringa oleifera; lectins; antibacterial activity; brine shrimp; bioassayDOI: 10.3329/jbs.v17i0.7112J. bio-sci. 17: 89-94, 2009

This study was performed to evaluate the antimicrobial activity of aerial parts of chloroform extract of Cassia auriculata L. The chloroform extract of C. auriculata were shown to possess an antimicrobial activity against two gram positive and two gram negative human pathogenic bacteria and fungi, viz. Bacillus subtilis, Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli and fungus cultures Candida albicans and Aspergillus niger by using disc diffusion method. The extract showed antibacterial activity at all concentrations selected, but only the extract with the concentration of 300µg/ml showed maximum antibacterial activity against all the organisms except Pseudomonas aeruginosa which are comparable with the standard control, amikacin. The anti fungal activity of chloroform extract of C. auriculata revealed significant effect against Candida albicans and Aspergillus niger with the net inhibition zone of 14 and 14 mm, respectively at 300µg/ml concentration, which is almost comparable with standard control, ketokonazole used as an antifungal agent. The phytochemical analysis showed the presence of alkaloids, carbohydrates, fixed oils, fats, tannins, gum & mucilage, flavonoids, saponins, terpenoids, lignin and sterols. It is concluded that the antimicrobial activity showed by the plant was due to the presence of these phytochemicals. Further studies are highly needed for future drug development.DOI: http://dx.doi.org/10.3329/icpj.v2i6.14869 International Current Pharmaceutical Journal, May 2013, 2(6): 105-108

The excessive use of chemical preservatives is a serious problem worldwide, which necessitates the discovery of new classes of antimicrobials from other sources like herbs and spices for preservation of food and/or food products. In this study, antibacterial activity of essential oils (EOs) such as cinnamaldehyde and carvacrol were tested against four foodborne pathogens viz Staphylococcus aureus ATCC 25923, Shigella dysenteriae-I MJ-84, Escherichia soli ATCC 25922, Vibrio cholerae ATCC 6395 and two food spoilage bacteria viz Pseudomonas aeruginosa ATCC 27853 and Klebsiella rhizophila ATCC 13882, respectively, using disc diffusion method. These EOs were found to inhibit both categories of bacteria. Cinnamaldehyde and carvacrol showed maximum 30.0 ± 0.2 and 27.5 ± 0.5 zones of inhibition, respectively against S. aureus. Pseudomonas aeruginosa was found resistant against carvacrol. Cinnamaldehyde and carvacrol was determined. Both showed antibacterial activity after treatment at 100°C for 30 min suggesting that high temperature does not affect the activity. Both the EOs have a broad pH range and exhibited highest activity at pH 7.0, suggesting that they remain un-dissociated at pH change. The MIC and MBC values of cinnamaldehyde ranged between 0.125 and .0 %, and 0.25 and 2.0 %, respectively and MIC and MBC values of carvacrol ranged between 0.125 and 0.5%, and 0.25 and 1.0 %, respectively. The results of this study confirmed the possibility of using cinnamaldehyde and carvacrol in preventing the growth of foodborne pathogens and spoilage bacteria and extend the shelf life of foods.

Phytochemistry, antioxidant and antibacterial activities of different solvent extracts of Chromolaena odorata leaves obtained by direct and sequential extraction were compared in this study. Antibacterial evaluation of the extracts was performed through a disc diffusion method. The results revealed that the solvents, Petroleum ether and Ethyl acetate showed the presence of a majority of the phytochemicals, Chloroform extract yielded maximum TPC and TAA and ethyl acetate yielded higher TFC when compared to other solvents. Ethanol and chloroform extracts showed lower concentrations of IC50 against DPPH and NO radicals respectively. Acetone recorded the maximum zone of inhibition against Staphylococcus aureus and Pseudomonas aeruginosa; ethyl acetate against Bacillus subtilis and Chloroform against Streptococcus mutans. Among the solvents studied for phytochemical content and bioactivities, ethanol showed a higher level of phytochemical extraction and better bioactivities. As a direct solvent extraction of C. odorata showed better efficiency when compared with sequential extraction, the study strongly recommends the use of a direct extraction method.

Shallot (Allium ascalonicum Linn.) is one of the typical plants of Central Sulawesi which is used as traditional medicine such as to treat infectious diseases. This study aims to determine the fractions that have high activity from bulbs and leaves in inhibiting the growth of Shigella dysenteriae bacteria and determining the organic compounds that have antibacterial activities. Extraction was carried out by maceration method using ethanol 96% for both samples. Liquid-liquid fractionation was used as a fractionation method using hexane, ethyl acetate and water  solvents, sequenly. The antibacterial activity test used the diffusion method with the pile technique and TLC-bioautography. The results showed that ethyl acetate fraction gave the highest activity of bulbs samples, while in leaves samples ethyl acetate fraction and hexane fraction were able to provide good inhibitory activity. The organic compounds were identified by thin layer chromatography method. Flavonoids compounds have identified for bulbs samples (Rf 0.18). In the leaves samples, steroids compounds were identified in the ethyl acetate fraction (Rf 0.62) and terpenoid compounds (Rf 0.48) in the hexane fraction. Based on the result, the shallot is potentially be developed as an antibacterial material.

The aim of this study is to investigate in vitro antioxidant and antibacterial activities of the aqueous and hydroethanolic extracts for aerial parts of Herniaria hirsuta. Extracts were screened for their possible antioxidant activities by three tests: DPPH free radical-scavenging, reducing power, and molybdenum systems. The screening of antibacterial activity of extracts was individually evaluated against sixteen bacteria species using a disc diffusion method. Flavonoids, total phenols, and tannins content were performed for both extracts. It shows higher content in the hydroethanolic extract. The hydroethanolic extract showed a significant antioxidant activity for the three methods studies to the aqueous extract, but nonsignificant results compared to the reference (BHT). However, both extracts have negative effect on the strains studies for the antibacterial activity.

Objectives: In order to investigate alternate therapeutic option, this study was carried out to assess the in vitro antibacterial activity of gel extract of Aloe barbadensis against multiple antibiotic resistant Pseudomonas aeruginosa isolated from wound specimens. Methods: A total of 180 different wound specimens collected in a hospital, were subjected to isolate and identify P. aeruginosa by cultural methods. Antibiotic susceptibility testing was done by Kirby- Bauer disc diffusion method to screen multidrug resistant isolates. A. barbadensis extracts were prepared using aqueous and organic solvents and their in vitro inhibitory action was evaluated by agar well diffusion methods. Results: Out of total, 38 (21.1%) of the wound specimens showed the occurrence of P. aeruginosa, among which 15 (39%) isolates were multi-drug resistant. Organic extracts of various concentrations (0.2 - 0.8 v/v %) inhibited 66.7% of MDR and all non-MDR (n = 23) P. aeruginosa with zone of inhibition ranging from 9.5 ±1.0 to 21.3 ± 2.2 mm but not by aqueous extract. A positive Pearson’s correlation (r=0.983) was found between antibacterial effect and concentrations of the extracts. The antibacterial activity of organic extracts was statistically associated with antibiotic resistance profile of the organism (p<0.05). Conclusion: Organic extracts of A. barbadensis revealed variable in vitro inhibitory action against both MDR and non-MDR P. aeruginosa isolated from wound specimens. Although further confirmation is needed, aloe gel extract may be applied as an alternate treatment option.
