Background: This work aims at the assessement of anti-inflammatory and anti-hemolytic effect of Malva sylvestris. 
 
Methods: The anti-inflammatory potential was evaluated by the inhibition of protein denaturation method. It was followed by the study of anti-hemolytic potential, based on two methods (haemolysis by hydrogen peroxide (H2O2) and by hypotonic haemolysis).&nbsp; 
 
Result: The macerated aqueous extract of M. sylvestris (250 &micro;g/ml) exhibited the highest inhibition percentage of&nbsp; BSA denaturation compared to other extracts but it appeared to be slightly lower than the drug diclofenac sodium (80.97&plusmn;1.23%). On the other hand, the macerated aqueous extract showed more protective power against haemolysis (93.42&plusmn;3.45%). While it was almost similar to the percentage recorded for ascorbic acid (93.68&plusmn;3.21%). For the second method, it was observed that the decocted acetone extract of M. sylvestris showed a rate of haemolysis inhibition which was the highest (98.09&plusmn;1.26%) but that it remained slightly lower than aspirin (98.77&plusmn;0.44%). All of these results showed that M. sylvestris extracts have interesting anti-inflammatory and anti-haemolytic potential and therefore have considerable interest as an alternative treatment against inflammatory mechanisms.

Evaluation of the Anti-inflammatory and Anti-hemolytic Potential of Polyphenolic Components of Common Mallow (Malva sylvestris)

<div>Background: Coniferous tree species typical of the central part of Russia can be evaluated not only as sources of wood but also as a raw material for obtaining biologically active substances. 
 
Methods: A comparative evaluation of needle juices of Pinus sylvestris and Picea abies in the summer and winter periods was the objective of this study and carried out in this study by chemiluminescence analysis and testing for membrane-protective activity. Juices were evaluated for the content of flavonoids and ascorbic acid, which some authors suggest are markers of stress in plants. An increase in the content of flavonoids and ascorbic acid in Pinus sylvestris L. in the summer period is a sign of an adaptive reaction of plants to the high intensity of ultraviolet radiation, which is typical for the growing conditions of pine as a photophilous plant. An increase in these indicators in Picea abies L. in winter is a sign of the plant stress response to low temperatures.&nbsp; 
 
Result: The membrane-protective activity of needle juices concerning peroxidation and osmotic hemolysis was revealed, which is more prominent in Pinus sylvestris L. needle juice. The analysis revealed more prominent antioxidant properties in the juice of Pinus sylvestris L. needles compared to that of Picea abies L. both in summer and in winter.</div>
