Effects of the Salt Stress Duration and Intensity on Developmental and Physiological Features of the Moss .

The two accessions of the polytrichaceous moss species , namely German and Serbian genotypes, were subjected to salt stress, aiming to study the species' developmental and physiological features. Various concentrations of sodium chloride were applied to an axenic culture of the two moss genotypes, and the growth parameters as well as physiological feature changes were followed. As inferred by the morpho-developmental parameters and survival index, the Serbian genotype showed higher resistance to salt stress as compared to the German one.

The estimation of the traditionally used yarrow (Achillea millefolium L. Asteraceae) oil extracts with anti-inflamatory potential in topical application.

Ethnopharmacological Relevance: Olive or sunflower oil yarrow extracts have been extensively used against inflammatory disorders and skin wound healing in traditional medicine.

Aim Of The Study: To evaluate oil yarrow extracts traditional use in treatment of topical/dermatological skin impairments, sodium lauryl sulfate test was applied, and in vivo measuring of the biophysical parameters (erythema index, skin capacitance and the pH of the skin) in the artificially irritated skin was performed. As traditionally olive and sunflower oil have been used equally for extracts production, the experiment was carried out to investigate whether any of the oil extractants has the advantage over the other, and if the method of extraction might influence the desired activity.

[Manufacturing process of high quality phytopreparation on example of herbal sedative].

Introduction: Rational phytotherapy is a modern concept of using plant-originated drugs which has emerged from the need to improve phytotherapy in order to make the use of herbal remedies more efficient and safer. The aim of this study was to give the health-care workers more information on the manufacturing process of high quality phytopreparation following principles of Good Manufacturing Practice and Good Laboratory Practice on the example of herbal sedative, Odoval S capsules.

Material And Methods: This study was designed to reflect the production process of a high-quality and safe herbal remedy, starting from defining the formulation and the production procedure to the quality control of raw materials, characterization of the final product, and testing stability of active ingredients in the capsules.

HPLC assay of acetylsalicylic acid, paracetamol, caffeine and phenobarbital in tablets.

This paper present a HPLC method for simultaneous determination of acetylsalicylic acid, paracetamol, caffeine and phenobarbital in tablets, using chromatographic system consisting a Bio Rad 18 01 solvent pump, Rheodine 71 25 injector and Bio Rad 18 01 UV-Vis Detector. Separation was achieved using Bio SiL HL C18, 5 microm, 250 x 4.6 mm column.

Quantitative analysis of analgoantipyretics in dosage form using planar chromatography.

In the therapy of pain of weaker genesis, frequently used drugs usually represent a mix of analgoantipyretics of different chemical structures, mostly derivatives of salicylic acid, pyrazolone and p-aminophenol as well as derivatives of propionic and acetylsalicylic acid. For the determination of these drugs, different chromatographic methods have been applied, mostly HPLC, due to the the lower polarity (pyrazolones derivatives) and thermolability, as well as nonvolatility of compounds investigated. TLC method, considering advantages which include simplicity, reasonable sensitivity, rapidity, excellent resolving power and low cost has been successfully explored for the determination of analgoantipyretic compounds.
