Further Directions It is apparent that a variety of studies are needed to explore the established data.

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 Gm -ve Escherichia coli.

Antibiotic activity Recent studies indicate evidence of antibiotic properties of some bryophyte species, incongruent with my results. In our study, none of these atnimicrobial displayed any activity. All extractions were performed with ethanol. All extractions were performed with methanol. The homogenous journsl liquid of the crude ethanolic extracts was used to impregnate the diffusion discs with antibiotic activity.

Average precipitation in Vancouver. Lastly, Hylocomium splendens has shown antibiotic activity against nine Gram-positive bacteria Ellis from the field in Vancouver, British Columbia. The outer membrane is responsible for protecting the bacteria from an array of different antibiotics, detergents, and enzymes that would normally damage the inner member or peptidoglycan cell wall Six mm sterilized filter paper discs were then impregnated with the approximately nine drops of the homogenous extract.

For example, byophytes potential source of experimental error in the current experiment was failing to use filtration devices or rotoevaporation to isolate our antibiotic compounds. They lack roots and attach to their environment with rhizoids Marchantia polymorphia Frullania nisquallensis Lepidozia reptans Scapania bolanderi Conocephalum conicum Plagiochila porelloides Porella cordaeana Lunularia cruciata.


This suggests that detectable antibacterial compounds are present in most taxa of liverworts Bryophytes represent the bryophyges largest group of green land plants after angiosperms, and are taxonomically placed between algae and pteridophytes 6. The bryophytes group consists of three subgroups: Furthermore, bryophytes utilize the sporangium for reproduction via sporulation but they neither flower nor produce seeds Bacterial sensitivities Gram-positive bacteria, B.

However, there have been few studies to screen and confirm the medicinal potential of bryophytes in North Americans for antibiotic activity. This would provide evidence to support current results.

All extract activity was standardized using comparable amounts of dried plant material and quantities of alcoholic extraction medium. A John Flynn Scholarship. Journal of Botanical Laboratory No.

Animal and human studies would also include infection prevent and treatment. 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.

Lastly, this study aims to determine whether ethanolic and methanolic extracts from similar bryophytes show significant differences in the relative antimicrobial activity. Historically, a large number of medicinal plants were discovered and used by the aboriginal people to treat illnesses 4.

Antibiotics were used as positive controls antimicrobixl the bacteria. Antibacterial activity in extracts of some bryophytes from China and Mongolia. It is apparent that a variety of studies are needed to explore the established data. Any part of the plant may contain active components.

Antibacterial Activity of Extracts from Some Bryophytes

Presently, over new compounds have been isolated with potential antibiotic qualities6. Atricum selwynii and Sphagnum palustre have also shown activity against a variety of Gram-positive and Gram-negative bacterial species 1,2, Gender and the management of cardiovascular disease. Six mm sterile filter paper discs were impregnated with extract and placed on seeded agar. Before extraction all plant material collected was washed with distilled water to remove any adhering soil or extraneous material.


One and half grams of the ground material were extracted in 25ml of methanol over 24 hours.

These groups exhibit an abundant distribution in China, Europe and North America and current estimates suggest that approximately species of mosses, species of liverworts and species of hornworts exist worldwide 9. The disc diffusion assay technique was used to evaluate antimicrobial activity.

The Bryologist 82 2: 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. Therefore, further studies could include performing more antibiotic screenings with larger variety bryophytes, against a huge variety of potential bacterial species. None of the mosses showed any antibiotic activity when extracted with methanol.

Marchantia polymorphia Frullania nisquallensis Lepidozia reptans Scapania bolanderi Conocephalum conicum Lunularia cruciata Plagiochila porelloides Porella cordaeana. Antimicrobial, wound healing and antioxidant activity of Plagiochasma appendiculatum Lehm. Banana Snapping in Innisfail: Further research will be needed to confirm indications that P.

These values could then be compared to the standard reference antibiotics for the development of commercial drug products. The onlyexception was Polytrichastrum alpinum, which showedindeterminate antibiotic response. Furthermore, Asakawa suggests that oil bodies are easily extracted with alcoholic extraction methods, while the other classes of bryophytes lack oil bodies, making antibiotic activity more difficult extract.

In addition, isolating the antibiotic compounds by Nuclear Magnetic Resonance and Mass Spectrophotometry allows for examination of compound structure.
