This reference work provides a comprehensive overview of bioactive compounds investigated in bryophytes and pteridophytes and explores their nutritional, biological, pharmacological and ecological effects. Bryophytes are cosmopolitan lower plants that are rich in phytochemicals including fatty acids, tocopherols, phenolics, terpenoids. Additionally, these plants contain bibenzyls, bis-benzyls, and polyketides which have been demonstrated to have antimicrobial, anti-inflammatory, and cytotoxic activities. Pteridophytes are another group of lower vascular plants which were reported to have...
