Anti-inflammatory properties of ethanolic root extract of Eremurus persicus (Jaub and Spach) Boiss, a Kurdish herbal remedy

This study reports for the first time a preliminary phytochemical and biological screening of ethanolic extract (EE) from roots of Eremurus persicus (Jaub and Spach) Boiss, a Kurdish herbal remedy for treating inflammatory disorders. The phytochemical analysis was performed by thin layer chromatography and it revealed the presence of flavonoids and antracenones. The total phenolic compounds were also determined. Free radical scavenging (FRS) effect was evaluated by 2, 2-diphenyl-1-picrylhydrazyl (DPPH) assay and the anti-inflammatory activity investigated by evaluating the inhibition of in vitro lymphocyte proliferation. To exclude citotoxic effect of EE, cell viability tests were also performed. Overall, biological investigation showed that the E. persicus (Jaub and Spach) Boiss root EE possess an interesting anti-inflammatory activity without cytotoxic effects. Key words: Anti-inflammatory activity, Kurdish ethnomedicine, Eremurus persicus (Jaub and Spach) Boiss, ethanolic root extract.

THE SECRETORY TISSUE OF ALOES AND THEIR ALLIES

ABSTRACT The presence of thin-walled parenchymatous cells in the inner bundle sheath of species of the liliaceous genera Aloe, Chamaealoe, Astroloba, Lomatophyllum, Gasteria, Haworthia, Asphodeline, Asphodelus, Bulbine, Eremurus and Trachyandra was observed and described. Some species, however, have lignified sclerenchymatous cells in this position and this is general in Kniphofia. Cells in this region produce a secretion in the form of a copious exudate in many species of Aloe, or much sparser contents in the case of related genera. The leaves of most species contain small amounts of anthraquinones, while the related anthrone-C-glycosides accumulate in others. A wide range of other phenolic substances occurs, recognized as distinct zones on thin layer chromatograms, but mainly consisting of unidentified compounds. It is not certain if synthesis occurs in the thin-walled bundle sheath cells or if these have only a storage function. Another layer of rather smaller parenchymatous cells in the outer bundle s...
