Antimicrobial, wound healing and antioxidant brgophytes of Plagiochasma appendiculatum Lehm. Lastly, this study aims to determine whether ethanolic and methanolic extracts from similar bryophytes show significant differences in the relative antimicrobial activity.

The amount of lost activity is dependent on the compounds extracted and the length of drying time.

Introduction T he occurrence of antibiotic substances in bryophytes has been well documented by botanists and microbiologists 1,2. Journal of Botanical Laboratory No.

Before extraction all plant material collected was washed with distilled water to remove any adhering soil or extraneous material. Once significant antibiotic activities have been isolated, MIC and MBC would be performed to determine antibiotic efficacy.

Since nearly all of the identified biologically active or antibiotic substances from plants have antimicrkbial identified as aromatic or saturated organic compounds, it was most efficient to obtain the compounds through ethanolic or methanolic extractions. Gm —ve Klebsiella pneumoniae. Bartramia pomiformis, Leucolepsis acanthoneuron, Frullania nisquallensis showed antibiotic activity when ethanolic extractions where used but not when methanolic extracts were used.

Lichenol Rev Bryol They lack roots and attach to their environment with rhizoids Furthermore, I would like to thank the University of British Columbia for providing me with resources and facilities to conduct my experiments and research.

The outer membrane is responsible for protecting the bacteria from bryophhtes array of different antibiotics, detergents, and enzymes that would normally damage the inner member or peptidoglycan cell wall Marchantia polymorphia Frullania nisquallensis Lepidozia reptans Scapania bolanderi Conocephalum conicum Lunularia cruciata Plagiochila porelloides Porella cordaeana.

The Bryologist 82 2: Table 4 Known active compounds extracted with solvents: Furthermore, re-testing bryophytes that performed differently from documented results could allow for greater understanding of the factors affecting activity.

This clearly demonstrates the importance of using a multitude of extraction compounds and methods to isolate antibiotic compounds. Consequently, bryophytes remain small and flourish in places where there is an abundant water supply However, unlike vascular plants, water and minerals are iournal chiefly by the thin leaves of the plant as the rain washes through the moss, not from roots The effectiveness of liverworts and mosses, solely against Gram-positive bacteria supports the notion that they are more vulnerable Mark Douglas Russell 1.


Table 4 lists some of the known compounds which have xntimicrobial extracted from methanolic and ethanolic extracts. The sporophyte typically consists of animicrobial unbranched seta, and a single terminal sporangium 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.

Reproductive organs were used in identification. 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. Occurrence of antimicrobial substances in chlorophyllose plants growing in Florida. Presently, over new compounds have been isolated with potential antibiotic qualities6.

Antibacterial Activity of Extracts from Some Bryophytes

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

Pure and Applied Chemistry, 79 4: Atricum selwynii and Sphagnum palustre have also shown activity against a variety of Gram-positive and Gram-negative bacterial species 1,2, Ellis from the field in Vancouver, British Columbia.
