Microorganisms and helminthes can cause serious diseases in humans as well as in animals. The use of antimicrobial and antihelminthic drugs have created selective pressure and caused resistance to antibiotics used against them, thus it necessitates the use of honey bee’s derived natural products. One such bee derived product is pollen, collected by worker honey bees from the flowering plants and modify it by adding its salivary secretions. The present study embodies use of pollen as antimicrobial and antihelminthic substance. Among microorganisms 4 Gram (+ve) bacteria; (Bacillus subtilis, Staphylococcus epidermidis, Staphylococcus aureus, Streptococcus pneumoniae) and 3 Gram (-ve) bacteria; (Escherichia Coli, Pseudomonas aeruginosa, Salmonella enteric) and 2 yeasts (Candida albicans and Saccharomyces cerevisiae) were used and the methodology used disc diffusion assay and broth dilution method. The antihelminthic effect was observed among amphistomes via bioassay method under in vitro conditions. For observations three types of pollen extracts (ethanolic, methanolic and water extract) were prepared and positive controls used were; Ampicillin for antibacterial, Amphotericin B for antifungal and Albendazole for anti-helminthes. The antimicrobial activities were determined by measuring the zones of inhibition diameters in millimeters after 24 hours of incubation at optimum temperature for each microbe and also by broth dilution method. Results obtained showed that the water extract of pollen was found to be most effective against bacteria used in the present study where; Gram (+ve) bacteria were more susceptible as compared to the Gram (-ve) bacteria. It was also observed that among yeasts; Saccharomyces cerevisiae was more susceptible towards ethanolic extract of pollen while Candida albicans showed more inhibitions towards water extract of pollen. Results also demonstrated that none of the extracts of pollen was found to be effective against Helminthes (amphistomes) used in the present study.

Abstract Objective Oral candidiasis is an infection caused by pathogenic fungi Candida albicans, with a considerably high prevalence of 20 to 72%. Indian camphorweed (Pluchea indica) also known as “beluntas” as the local name has been known as a traditional medicine in Indonesia. The objective of this study is to research the minimum inhibitory concentration (MIC) and the minimum fungicidal concentration (MFC) of beluntas ethanolic extract against the growth of C. albicans. Materials and Methods The MIC and MFC were measured by microdilution assay and total plate count respectively with a variation of solvents (DMSO 1%, 10%, and 4%) and beluntas extract with concentrations between 0.3125 and 200 mg/mL. Amphotericin and nystatin were used as a comparison. Statistical Analysis One-way analysis of variance and posthoc Tukey test were used to determine the significant difference between treatments. Results It was found that the MIC ranged from 50 to 200 mg/mL in the test with DMSO 10% solvent and MFC was found to be at a concentration of 200 mg/mL. However, there is a significant inhibitory effect and killing effect from DMSO 10% against C. albicans (p = 0.000). MIC was also found within concentrations of 100 mg/mL of beluntas extract in DMSO 4%. In this study, the DMSO 4% concentration neither showed significant inhibitory effects nor killing effects; therefore, the result was acceptable (p = 0.357). Conclusion Ethanol extract of beluntas (P. Indica) has the potential of being an antifungal agent with inhibitory activity in concentrations ≥100 mg/mL, which is similar to nystatin (p = 0.278). The MFC for the extract was above 100 mg/mL, which cannot be measured with this method as a higher concentration of DMSO is needed, which had a toxic effect on the tested fungi.

Candida albicans is a normal microflora in the oral cavity which can be an opportunistic pathogen that could cause oral candidiasis when there are underlying predisposing conditions. Papaya as one of the most widely grown herbal plants in Indonesia has been known to cure diseases. Unused papaya peel only became a waste; however, the papaya peel is known to contain active compounds that have antifungal effect, especially raw ones. This study aimed to determine the antifungal effect of raw papaya peel extract of Californian variety and determine the minimum inhibitory concentration (MIC) of this extract on clinical isolates of C. albicans. This study was an experimental laboratory study with post-test only control group design. Ethanol-based extract of papaya peel was obtained from maceration process using 96% ethanol. Antifungal effect testing was carried out in vitro using disc diffusion method (Kirby-Bauer) on clinical isolates of C. albicans. The concentration of Ethanol extract of papaya peel used consisted of 2.5%, 5%, 10%, and 20% with positive control (nystatin) and negative control (distilled water). The results showed that 2.5%, 5%, 10%, and 20% papaya peel extracts were able to inhibit the growth of C. albicans with 2.5% concentration of raw papaya peel extract as minimum inhibitory concentration. Ethanol extract of raw papaya peel of Californian variety with 2.5%, 5%, 10%, and 20% concentrations has small antifungal effect against clinical isolates of C. albicans.

A series of diazenyl chalcones was prepared by base catalyzed Claisen-Schmidt condensation of synthesized hydroxy substituted acetophenone azo dye with various substituted aromatic/ heteroaromatic aldehydes. The structural conformation of synthesized chalcones was done by a number of physicochemical and spectral means like FTIR, UV-visible, mass, NMR spectroscopy and CHNS/O analysis. These diazenyl chalcones were assessed for their in vitro antimicrobial potential against several Gram-negative, Gram-positive bacterial and fungal strains by serial tube dilution method. The fluconazole and cefadroxil were used as standard drugs. The target compounds were also evaluated for their antioxidant potential by DPPH assay. (2E)-3-(2,4-Dichlorophenyl)-1-(4-((2,6- dihydroxyphenyl)diazenyl)phenyl)prop-2-en-1-one (C-7) had shown very good antimicrobial potential with MIC ranges from 3.79 to 15.76 μg/ml against most of the tested microorganisms. Most of the synthesized diazenyl chalcones were found to be active against B. subtilis. The (2E)-1-(5-((2-Chloro- 4-nitrophenyl)diazenyl)-2-hydroxyphenyl)-3-(2-hydroxynaphthalen-1-yl)prop-2-en-1-one (C-10) had shown high free radical-scavenging activity when compared with the ascorbic acid as the reference antioxidant.

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.

Polygoni Multiflori Radix Praeparata (PMRP), as the processed product of tuberous roots of Polygonum multiflorum Thunb., is one of the most famous traditional Chinese medicines, with a long history. However, in recent years, liver adverse reactions linked to PMRP have been frequently reported. Our work attempted to investigate the chemical constituents of PMRP for clinical research and safe medication. In this study, an effective and rapid method was established to separate and characterize the constituents in PMRP by combining ultra-high performance liquid chromatography with hybrid quadrupole-orbitrap mass spectrometry (UHPLC-Q-Exactive Orbitrap-MS). Based on the accurate mass measurements for molecular and characteristic fragment ions, a total of 103 compounds, including 24 anthraquinones, 21 stilbenes, 15 phenolic acids, 14 flavones, and 29 other compounds were identified or tentatively characterized. Forty-eight compounds were tentatively characterized from PMRP for the first time, and their fragmentation behaviors were summarized. There were 101 components in PMRP ethanol extract (PMRPE) and 91 components in PMRP water extract (PMRPW). Simultaneously, the peak areas of several potential xenobiotic components were compared in the detection, which showed that PMRPE has a higher content of anthraquinones and stilbenes. The obtained results can be used in pharmacological and toxicological research and provided useful information for further in vitro and in vivo studies.

Background: Fluconazole (FLZ), a potent antifungal medication, is characterized by poor water solubility that reduced its antifungal efficacy. Objective: This study aimed to prepare FLZ-loaded polymeric nanoparticles (NPs) by using different polymers and techniques as a mean of enhancing the antifungal activity of FLZ. Methods: NP1, NP2, and NP3 were prepared by the double emulsion/solvent evaporation method using PLGA, PCL, and PLA, respectively. The ionotropic pre-gelation technique was applied to prepare an alginate/chitosan-based formulation (NP4). Particle size, zeta potential, encapsulation efficiency, and loading capacity were characterized. FT-IR spectra of FLZ, the polymers, and the prepared NPs were estimated. NP4 was selected for further in-vitro release evaluation. The broth dilution method was used to assess the antifungal activity of NP4 using a resistant clinical isolate of Candida albicans. Results: The double emulsion method produced smaller-sized particles (<390 nm) but with much lower encapsulation efficiency (< 12%). Alternatively, the ionic gelation method resulted in nanosized particles with a markedly higher encapsulation efficiency of about 40%. The FT-IR spectroscopy confirmed the loading of the FLZ molecules in the polymeric network of the prepared NPs. The release profile of NP4 showed a burst initial release followed by a controlled pattern up to 24 hours with a higher percent released relative to the free FLZ suspension. NP4 was able to reduce the value of MIC of FLZ by 20 times. Conclusion: The antifungal activity of FLZ against C. albicans was enhanced markedly via its loading in the alginate/chitosan-based polymeric matrix of NP4.

Dental plaque prevention can be achieved by inhibition of mouth cavity microbes to built biofilm. Kaempferia galanga rhizome has been known as a potential antibacterial agent. This research aimed to reveal the potency of Kaempferia galanga extract and essential oil as anti plaque active agents, based on their in vitro inhibitory activity against the planktonic growth and biofilm of Streptococcus mutans ATCC 21752. Kaempferia galanga extract was obtained by defatting dried-pulverized samples in petroleum ether prior to immersion in 70% ethanol. The fresh rhizome was steam-hydro distilled for 6 h to yield the essential oil. Antibacterial and anti biofilm assays were measured by micro dilution technique on polystyrene 96-wells micro titer plates at 37°C. The percentage of inhibition was calculated by comparing the absorbance of samples to the vehicle (control) measured by micro plate reader at 595 nm. Biofilms formed were first stained by 1% crystal violet. The above assays were performed in triplicates. This study revealed that both K. galanga rhizome essential oil and ethanolic extract showed antibacterial and antibiofilm activity towards S. mutans. The ethanol extract showed MIC90 value at 0.091% w/v and MBC at 2.724% w/v for antibacterial activity; IC50 at 0.048 % w/v for anti biofilm formation activity; and EC50 at 0.052%w/v for biofilm degradation activity. Until the highest concentration tested (0.6%w/v), the MIC90 and MBC values of the essential oil were not revealed, but higher biofilm inhibitory activity i.e. IC50 at 0.025 % w/v; and EC50 at 0.034 %w/v were observed. Key words: biofilm inhibitor, antibacterial, Kaempferia galanga
