NOMENCLATURE DU GENRE EVERNIASTRUM HALE (LICHENES: PARMELIACEAE)

3.6. Ultrastructure De La Spermiogenese Et Du Spermatozoïde Du Genre

This paper describes the ultrastructure of spermiogenesis and the mature spermatozoon of two Dipylidiidae cestodes, Joyeuxiella echinorhynchoides and J. pasqualei. In both species, spermiogenesis follows the type III described by Bâ and Marchand for the cyclophyllideans. Nevertheless, it is interesting to note the presence of striated roots associated with the centrioles. The spermatozoon prese...

Bioactive derivatives obtained from lecanoric acid, a constituent of the lichen Parmotrema tinctorum (Nyl.) Hale (Parmeliaceae)

With the aim of obtaining new compounds with potential antifungal activity, lecanoric acid, a chemical constituent of the lichen Parmotrema tinctorum and its derivatives prepared from structural modification were tested against the fungus Cladosporium sphaerospermum, by employing the bioautographic method. Activity of the derivatives ranged from 10to 1-μg concentrations. Results demonstrated th...

ASSESSMENT OF THE ANTIOXIDANT ACTIVITY AND PHYTOCHEMICAL ANALYSIS OF A LICHEN, EVERNIASTRUM CIRRHATUM (FR.) HALE ex. SIPMAN

Free radicals generated in system induce oxidative stress related diseases. Recent research is focused on plants and phytocompounds to avoid various side effects. The present study is aimed to evaluate the free radical scavenging potential along with phytochemical screening of the 70% methanolic extract of a lichen, Everniastrum cirrhatum (Fr.) Hale (ECME). ECME was tested for its in vitro tota...
