Terpenoid and Steroid Components of Selected Liverworts
Bryophytes, approximately represented by 24.000 species in the world, are placed between algae and pteridophytes. Several bryophytes have been used to cure burns, bruises, external wounds, pneumonia, and bacteriosis in North America, China, and Europe [1, 2, 3, 4].
The Marchantiophyta (Liverworts) are the second largest group in the classification of the Bryophytes. They are estimated to consist of ~8000 species in 380 genera and 74 families and considered to be the oldest terrestrial plants, although no strong scientific evidences have appeared in the literature [1, 2, 3, 4].
