Occurance of antibiotic activity in Conocephalum conicum, Mnium umdulatum and Leptodictyum riparium. Streptomycin appeared most effective against E. For example, Lunularia cruciata, Plagiochila porelloides and Marchantia polymorphia showed inhibition zones greater than 2.

All extracts were stored at room temperature. For example, a potential source of experimental error in the current experiment was failing to use filtration devices or rotoevaporation to isolate our antibiotic compounds.

This may have affected our results. Mosses and liverworts usually have leaves with a thickness of one cell, except along the costa and the alar cells, which facilitate diffusion However, reports antimicrkbial ethnobotanical research into this plant group are minimal in North America 1. All assays were carried out in triplicates.

A longitudinal study of mental health morbidity markers in a cohort of 1st year postgraduate medical students. Furthermore, Asakawa suggests that oil bodies are easily extracted with alcoholic extraction methods, while the other classes of bryophytes bryohytes oil bodies, making antibiotic activity more difficult extract.


British Columbian bryophytes against Gram-positive and Gram-negative bacteria will be used as evidence for antimicrobial action and efficacy. According to the literature, all of these species should have antimicroibal some antibiotic activity against B. A failure to do so could result in an inability to retrieve valuable information, and incorrectly dismissing potentially beneficial species. The disc diffusion assay technique was used to evaluate antimicrobial activity.

Preparation of Biologically Active Extracts: All extractions were performed with methanol.

MSJA | Medical Student Journal of Australia

The homogenous surface liquid of the crude methanolic extracts was used to impregnate the diffusion discs with antibiotic activity. All extract activity was standardized using comparable amounts of dried plant material and quantities of alcoholic extraction medium. The climate of South Western British Columbia is very antimicrpbial and humid, with an average of mm of rain per year Bryophytes typically grow in close association with each other. All extractions were performed with ethanol.

These values are approximately one third of the inhibition of reference antibiotics. The botanical names of the plants tested, habitat and collection date are antumicrobial in Table 1.

For example, Bartramia pomiformis, Leucolepsis acanthoneuron, Frullania nisquallensis showed antibiotic activity only using ethanolic extraction. Further research will be needed to confirm indications that P.


Antibiotic effects of Lunularia cruciata Bryophyta extract. On the other hand, McCutcheon et al states that there are few known natural antibiotic compounds with a high antibacterial activity against Gram-negative bacteria, which parallel our results.

Marchantia polymorphia Frullania nisquallensis Lepidozia reptans Scapania bolanderi Conocephalum conicum Lunularia cruciata Plagiochila porelloides Porella cordaeana.

I would like to gratefully acknowledge Dr.

The bolded compounds are partitioned exclusively by the particular solvent. Consequently, bryophytes remain small and flourish in places where there is an abundant water supply A John Flynn Scholarship. Bryophytes represent the second largest group of green land plants after angiosperms, and are taxonomically placed between algae and pteridophytes 6. International Journal of Antimicrobial Agents, Historically, a large number of medicinal plants were discovered and used by the aboriginal people to treat illnesses 4.

Bfyophytes homogenous surface liquid of the crude ethanolic extracts was used to impregnate the diffusion discs with antibiotic activity. How did I get here?
