Helichrysum plicatum (Turkish Helichrysum) has been used in folk medicine for the treatment of gastric and hepatic disorders. The aim of the present study was to examine the relaxant activity of an extract of H. plicatum flowers on isolated rat ileum. Segments of ileum of rats were suspended in an organ bath. Cumulative concentrations of H. plicatum ethanol extract induced a relaxant effect on ...

The experiment was conducted to proof the new natural plant extracts (Fagopyrum Mill. (buckwheat), Crataegus ex L., (hawthorn), Hypericum L. (St -John's -wort's) and Helichrysum arenarium) and selected flavonoids as reference substances for the in vitro. The probing was performed as considering four different parameters: the antioxidant activity, the antiradical activity – DPPH test, the DPH te...

The ethnopharmacology of Madeira and Porto Santo Islands is extremely interesting because of the cultural and biogeographic features of this region, which make it a centre of medicinal plant diversity (richness of endemic flora, geographical isolation in the Atlantic sea, crosscultural influences, and past abundance of local healers). The medicinal flora of Madeira is composed of 259 species. S...

The aim of this study was to determine the antimicrobial effect of Helichrysum arenarium L. essential oil in "invitro" condition on the growth of seven microbial species including Bacillus subtilis, Escherichia coli, Staphylococcus aureus, Saccharomyces cereviciae, Candida albicans, Aspergillus flavus and Aspergillus parasiticus using micro-dilution method. The minimum inhibitory concentration ...

Helichrysum bellum Hilliard (Compositae: Inuleae: Gnaphaliinae) is described and illustrated. The genus Helichrysum, its position in the family, discussed, along with placement of Hilliard's Group 28 species relation to recent phylogenetic studies, compared Moeser's original his early revision. richness Drakensburg Alpine Centre commented on, especially some closely related H. bellum. Cultivati...

PREMISE OF THE STUDY Microsatellites were developed for the widespread Helichrysum odoratissimum (Asteraceae) to estimate gene flow across diploid populations and to test if gene flow occurs among other closely related lineages within this genus. METHODS AND RESULTS Ten primer pairs were developed and tested using populations across South Africa; however, only seven primer pairs were polymorp...

Eight new glycosides, everlastosides F (1), G (2), H (3), I (4), J (5), K (6), L (7), and M (8), were isolated from the methanolic extract of the flowers of Helichrysum arenarium. Their structures were elucidated on the basis of chemical and physicochemical evidence.
