Abstract

Pteridophytaare seedless vascular plants with life cycle characterized by alternating diploidsporophytic and haploidgametophytic phases. Both phases are well separated. The groupe includes divisions : Ryniophyta, Lycopodiophyta and Monilophyta. Ryniophytais fossil dvision. The largest and the most important division is Monilophyta. There are largemorphological differences between divisions of Lycopodiophyta and Monilophyta. Chemical compounds produced by plants are products of primary or secondary metabolism. Most of toxic or healing compounds in seedless vascular plants are products of secondary metabolism. Alkaloids, flavonoids, glycosides, tanninsand terpenes are compounds worthy of mentioning. The largest economical value lies in caol beds produced by extinct seedless vascular plant species during the carbon period. Extant species are used in pharmaceutical and cosmetic industry, in gastronomy and horticulture. Worlwide renowned seedless vascular plant species are Lycopodium clavatum, Equisetum arvense, Pteridium aquilium i Azolla filiculoides. Lycopodium clavatum and Equisetum arvenseare characterised by their high valuble medical properties while Pteridium aquilium and Azolla filiculoides by their economical value. Newer researches indicate that species Pteridium aquilium has high toxic and cancerous properties.
