For example, Bartramia pomiformis, Leucolepsis acanthoneuron, Frullania nisquallensis showed antibiotic activity only using ethanolic extraction. Antibiotic screening of medicinal plants of British Columbian native peoples.

Therefore, homogenous patches were desired with fresh tissue void of dead or dying material. Other tested plant species, were collected from homogenous plant populations. Since different populations of the same species may exhibit different antimicrobial activity, the time and place of collection, and habitat were recorded Table 1. Table 4 Known active compounds extracted with solvents: Plants of Coastal British Columbia.

Therefore, potential differences in seasonal collection, locality, or extraction and experimental procedure may have been factors that manipulated the results.

The bryophytes group consists of three subgroups: Lunularia cruciata also demonstrated the most significant antibiotic activity of all the bryophytes tested. In our study, none of these species displayed any activity.

Antibacterial Activity of Extracts from Some Bryophytes

Medical Student Journal of Australia. Antibacterial activity in extracts of some bryophytes from China and Mongolia. A failure to do so could result in an inability to retrieve valuable information, and incorrectly dismissing potentially beneficial species. Principles of Biochemistry 4th Edition.


Journal of Botanical Laboratory No. Giorn Bot Ital Lastly, the characteristic that distinguishes bryophytes from tracheophytes, vascular plants, is the persistent photosynthetic phase of the life cycle is haploid; gametophyte generation bryopnytes rather than the diploid sporophyte generation All the reference antibiotics showed dramatic activity against all the Gram-positive and Gram-negative bacteria.

Cuzco, Peru Honiara, Solomon Islands.

The disc diffusion assay technique was used to evaluate antimicrobial activity. I would like to gratefully acknowledge Dr. This suggests that specific antibacterial compound seffective against the selected bacterial species, tend to be isolated more effectively from liverworts and antlmicrobial using ethanol.

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. It is short lived and attaches to the gametophytes for all its nutritional needs.

Journal of Ethnopharmacology, A longitudinal study of mental health morbidity markers in a cohort of 1st year postgraduate medical students. Mark Douglas Russell 1. This could lead to further studies in synthetic production or chemical development.

Antibiotic Activity of Bryophytes. However, there have been few studies to screen and confirm the medicinal potential of bryophytes in North Americans for antibiotic activity. 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 One and half grams of the ground material were extracted in 25ml of methanol over 24 hours.


However, reports of ethnobotanical research into this plant group are minimal in North America 1. Therefore, the whole organism was collected wherever possible. However, few studies have been concerned with an in-depth analysis of the antimicrobial activity and efficacy of phytochemicals in different species of bryophytes from South Western British Columbia Bryophyta mossesMarchantiophyta liverworts or [hepatics] and Anthocerotophyta hornworts 7.

None of the 14 species of bryophytes antimicrobixl, from either of the alcoholic extractions, showed any visible activity againstGram-negative Escherichia coli or Klebsiella pneumoniae. Therefore, further studies could include performing more antibiotic screenings with larger variety bryophytes, against a huge variety of bryophytea bacterial species.

How did I get here? Once rinsed, plants were kept in sealed paper bags, and placed in the refrigerator to prevent the subsequent drying or decay.

Tetrahedron 42 4Antimicrobila M. Presently, over new compounds have been isolated with potential antibiotic qualities6. Historically, a large number of medicinal plants were discovered and used by the aboriginal people to treat illnesses 4. They lack roots and attach to their environment with rhizoids Antibiotic effects of Lunularia cruciata Bryophyta extract. This clearly demonstrates the importance of using a multitude of extraction compounds and methods to isolate antibiotic compounds.

The screening results are listed in Table 2 and 3 for ethanolic and methanolic extractions respectively.
