Freeman New York, NY. All extractions were performed with ethanol.

For example, Bartramia pomiformis, Leucolepsis acanthoneuron, Frullania nisquallensis showed antibiotic activity only using ethanolic extraction.

Therefore, homogenous patches were desired with fresh tissue void of dead or dying material. These values could then be compared to the standard reference antibiotics for the development of commercial drug products. A failure to do so could result in an inability to retrieve valuable information, and incorrectly antimcrobial potentially beneficial species.

The application ranged from topical applications, to prevent infection, to internal consumption, facilitating relief from nausea 5.

The botanical names of the plants tested, habitat and collection date are listed in Table 1. Furthermore, bryophytes utilize the sporangium for reproduction via sporulation but they neither flower nor produce seeds The bryophytes group consists of three antimcrobial The homogenous surface liquid of the crude methanolic extracts was used to impregnate the diffusion discs with antibiotic activity.

All extracts were stored at room temperature. No related media found for this article. This would also allow one to test for broad spectrum antibiotic and narrow spectrum antibiotics. The disc diffusion assay technique was used to evaluate antimicrobial activity. However, unlike vascular plants, water and minerals are absorbed chiefly by the thin leaves of the plant as the rain washes through the moss, not from roots All the reference antibiotics showed dramatic activity against all the Gram-positive and Gram-negative bacteria.

Once rinsed, plants were kept in sealed paper bags, and placed in the refrigerator to prevent the subsequent drying or decay. A thorough overview of the fundamentals of Botany. Also, these compounds would be subjected to animal and human studies to determine their effectiveness on whole-organism systems, including toxicity and normal microbiota studies. Gm -ve Escherichia coli.

Banana Snapping in Innisfail: Lunularia cruciata also demonstrated the most significant antibiotic activity of all the bryophytes tested. Fourteen crude methanolic and ethanolic extracts of bryophytes from South Western British Columbia were screened for antibiotic activity against three bacterial strains with the bryophtyes diffusion method. Antibiotic Activity of Bryophytes.

Ellis from the field in Vancouver, British Columbia. Methanolic extractions The preliminary results of screening the alcoholic extracts of 14 species of bryophyte tested against three species antimicrobiall bacteria showed that there is a distinct difference between the antibiotic activities of the tested species in relation to the extraction method used.

The reference antibiotics showed a range of 5. The bacteria used were Bacillus subtilis, Escherichia coli, and Klebsiella pneumoniae. The screening results are listed in Table 2 and 3 for ethanolic and methanolic extractions respectively.


Journal of Ethnopharmacology Lichenol Rev Bryol Antimicrobial, wound healing and antioxidant activity of Plagiochasma appendiculatum Lehm. Giorn Bot Ital One and half grams of the ground material were extracted in 25ml of methanol over 24 hours.

Table 4 lists some of the known compounds which have been extracted from methanolic and ethanolic extracts. Table 1 Localities, habitats, and collection data of studied bryophytes. Bryophyta mossesMarchantiophyta liverworts or [hepatics] and Anthocerotophyta hornworts 7. This would provide evidence to support current results.

Antiviral screening of British Columbian medicinal plants. In addition, none of the mosses showed any antibiotic activity when methanolic extractions were used. Hundreds of medicinal bryophytes have been identified and classified in ethnobotanical literature johrnal potential antimicrobial agents 6,8,9, However, journa, of ethnobotanical research into this plant group are minimal in North America 1.

Therefore, potential differences in seasonal collection, locality, or extraction and experimental procedure may have been factors that manipulated the results. Furthermore, I would like to thank the University of British Columbia for providing qntimicrobial with resources and facilities iournal conduct my experiments and research.
