Tetrahedron 42 4Cowan M. Bryophyta mossesMarchantiophyta liverworts or [hepatics] and Anthocerotophyta hornworts 7. All extractions were performed with methanol.

Further research will be needed to vryophytes indications that P. Screening of potential antimicrobial plants requires crude aqueous or alcohol extracts and fine organic extraction methods.

Gender and the management of cardiovascular disease. The sporophyte typically anfimicrobial of an unbranched seta, and a single terminal sporangium Antimicrobiak crude methanolic and ethanolic extracts of bryophytes from South Western British Columbia were screened for antibiotic activity against three bacterial strains.

The bacteria used were Bacillus subtilis, Escherichia coli, and Klebsiella pneumoniae. The disc diffusion assay technique was used to evaluate antimicrobial activity. Table 2 Antibiotic activity in disc diffusion assays of bryophytes from South Western British Columbia and reference antibiotics. This clearly demonstrates the importance of using a multitude of extraction compounds and methods to isolate antibiotic compounds.


These values could then be compared to the standard reference antibiotics for the development of commercial drug products. Once significant antibiotic activities have been isolated, MIC and MBC would be performed to determine antibiotic efficacy.

It is apparent that a variety of studies are needed to explore the established data. Antibacterial activity in extracts of some bryophytes from China and Mongolia. Liverworts also demonstrated the greatest inhibition zone. A thorough overview of the fundamentals of Botany.

Therefore, the whole organism was collected wherever possible. Table 1 Localities, habitats, and collection data of studied bryophytes. Ellis for providing expertise and laughter throughout this project and field collections, and to Amy Singleton-Polster for her peer-criticisms.

The application ranged from topical applications, to prevent infection, to internal consumption, facilitating relief from nausea 5. Cuzco, Peru Honiara, Solomon Islands. I would like to gratefully acknowledge Dr. This includes thallus, sporophyte, aerial gametophyte and underground portions.

This may have affected our results. The average inhibition zone in ethanolic extracts ranged from 1. 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. All assays were carried out in triplicates. Lunularia cruciata also demonstrated the most significant antibiotic activity of all the bryophytes tested.


Bryophytes in this region are herbaceous plants that grow closely packed together in mats or cushions on rocks, soil, or as epiphytes on the trunks and leaves of forest trees All other species showing antibiotic activity were common among ethanolic and methanolic extracts.

Therefore, potential differences in seasonal collection, locality, or extraction and experimental procedure may have been factors that manipulated the results. The average inhibition zone in methanolic extracts ranged from 1. To explore the bryophytic potential in pharmaceutical applications, a quantitative and qualitative screening of S. National Climatic Data Cenetre. All extractions were performed with ethanol. Plants of Coastal British Columbia.

Biologically active compounds from bryophytes.

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. Should boys receive the Gardasil Vaccination?
