Further research will be needed to confirm indications that P. Mark Douglas Russell 1. Recently, the public demand for herbal medicine and the rise of antibiotic-resistant bacteria have motivated scientists to look for new natural sources with potential pharmaceutical capabilities 3.

However, reports of ethnobotanical research into this plant group are minimal in North America 1.

Ellis for providing expertise and laughter throughout this project and field collections, and to Amy Singleton-Polster for antimicrkbial peer-criticisms. Eating for Two – The common misconception in pregnancy.

International Journal of Antimicrobial Agents, Fourteen crude methanolic and ethanolic extracts of bryophytes from South Western British Columbia were screened for antibiotic activity against three bacterial strains with the disk diffusion method.

Native American food and medicinal plants 7. Hundreds of medicinal bryophytes have been identified and classified in ethnobotanical literature as potential antimicrobial agents 6,8,9, Therefore, the whole organism was collected wherever possible. Tetrahedron 42 4Cowan M. This may have affected our results.

The bolded compounds are partitioned exclusively by the particular solvent. It is short lived and attaches to the gametophytes for all its nutritional needs. Antibiotics were used as positive controls against the bacteria. Ellis from the field in Vancouver, British Columbia.

This could lead to further studies in synthetic production or chemical development. Antiviral screening of British Columbian medicinal plants.

Bartramia pomiformis, Leucolepsis acanthoneuron, Frullania nisquallensis showed antibiotic activity when ethanolic extractions where used but not when methanolic extracts were used. All the reference antibiotics showed dramatic activity against all the Gram-positive and Gram-negative bacteria. Furthermore, I bryo;hytes like to thank the University of British Columbia for providing me with resources and facilities to conduct my experiments and research.

This would provide evidence to support current results. Antibacterial activity in extracts of some bryophytes from China and Mongolia. According to the literature, all of these species should have shown some antibiotic activity against B.

The collections took place from October to November Furthermore, re-testing bryophytes that performed differently from documented results could allow for greater understanding of the factors affecting activity. C and Cardellina, J. Journal of Natural Products, Lastly, the characteristic that distinguishes bryophytes from tracheophytes, vascular plants, is the persistent photosynthetic phase of the life cycle is haploid; gametophyte generation occurs rather than the diploid sporophyte generation Pure and Applied Chemistry, 79 4: In addition, none of the mosses showed any antibiotic activity when methanolic extractions were used.


Antibacterial Activity of Extracts from Some Bryophytes

Presently, over new compounds have been isolated with potential antibiotic qualities6. Bryophytes typically grow in close association with each other. Methanolic extractions The preliminary results of screening the alcoholic extracts of 14 antimiicrobial of bryophyte tested against three species of bacteria showed that there is a distinct difference between the antibiotic activities of the tested species in relation to the extraction method used.

However, there have been few studies to screen and confirm the medicinal potential of bryophytes in North Americans for antibiotic activity.

Lunularia cruciata also demonstrated the most significant antibiotic activity of all the bryophytes tested. All samples were preliminarily washed to remove contaminants.
