From the flowers of meadowsweet and inflorescence of hawthorn the whole set of phenolic acids and flavonoids was analysed by TLC. Phenolic compounds were determined both as free ones and those liberated by hydrolysis. Moreover, ethyl ether and ethyl acetate extracts obtained from the analysed plants before and after alkaline and enzymatic hydrolyses were evaporated under reduced pressure and re...

In this work, the biosorption of Cr and Ni by Sargassum filipendula pre-treated with CaCl2 was studied. Kinetic and equilibrium experiments were carried out for monoand multi-component solutions in a batch reactor at pH 3.0 and 30 oC. The results from the kinetic experiments showed that Cr adsorbs slower than Ni. This behavior was explained by means of a mechanistic analysis, which showed that ...

The residue derived from the alginate extraction S. filipendula was applied for biosorption of aluminum aqueous medium. adsorptive capacity (RES) completely evaluated in batch mode. effect pH, contact time, initial concentration, and temperature assessed through kinetic, equilibrium, thermodynamic studies. biosorbent characterized prior post-Al by N2 physisorption, Hg porosimetry, He pycnometry...

The antifungal activity of secondary lichen metabolites extracted by means acetone and ethanol from Cetraria islandica, Cladonia mitis, C. rangiferina, Pseudevernia furfuracea Usnea dasopoga on the pathogenic fungi Fusarium oxysporum F. avenacuem was examined. compounds tested after their mixture with PDA medium before solidification. most active extracts inhibiting growth fungal mycelia contai...

The cytological features including chromosome numbers and detailed measurements of 46 populations ten Achillea species ( A. aleppica, bibersteinii, eriophora, filipendula, millefolium, nobilis, pachycephala, tenuifolia, vermicularis, wilhelmsii ) were reported from Iran. Sample plants seeds collected diff erent geographical regions Total length, long/ short arm ratio, centromere index, total fo...

This study was conducted to identify and classify the lichens; determine the diversity index and richness of lichens. A total of 36 species belonging to six genera under three families was identified. Lichen species were mostly found at moderate high altitudinal range with an elevation of 1,131 meters above sea level and open areas where they received adequate sunlight with high moisture and hu...
