Extraction and quantification of oxalic acid in leaves of plant species used in the treatment of chronic non-communicable diseases

Introduction: Chronic non-communicable diseases (CNCDs) are a group of diseases characterized by having the highest mortality and morbidity rates in the world. Despite the increase in new drug technologies, the use of medicinal plants as an aid in therapy for these diseases is a widespread reality. However, most plant species contain inorganic crystals of calcium oxalate, a product of plant metabolism, which has several functions in plant tissues. For the human species, its ingestion is associated with the arising of kidney problems such as urinary lithiasis, especially in people who have a predisposition to these conditions. Aim: To determine the amount of oxalic acid in plant species, which are used in the treatment of CNCDs. Methodology: After collection and characterization the plant species, aqueous and acidic extracts were obtained from 0.5 g of the plant drug of each species and, subsequently, were titrated with a standardized 0.02 mol.L-1 potassium permanganate solution and the concentrations of oxalic acid were expressed in g/100 g of dry vegetable drug. Result: The data obtained from the concentration of oxalic acid ranged from 4.58 ± 0.09 g/100 g to 17.21 ± 0.07 g/100 g and demonstrated that the concentrations from acid extraction are higher compared to the aqueous extraction, for all vegetables species analyzed. Methodological optimization was performed for the species that showed the highest results, Psidium guajava and Artocarpus heterophyllus. Conclusion: The data obtained can serve as input for medical decisions and for professionals who prescribe medicinal plants.

Distribution of 137Cs and 40K in the tissue of silver fir trees (Abies alba Mill.) from Lika (Croatia)

The research on activities of &lt;sup&gt;137&lt;/sup&gt;Cs and &lt;sup&gt;40&lt;/sup&gt;K, which was conducted on the silver fir (Abies alba Mill.) from Lika has included sampling of the trees in the field (rings of the bole from three different heights separated into bark, growth rings, roots, needles, shoots, and the soil surrounding the cut down trees), laboratory analysis of samples using the gamma-ray spectrometry and the statistical analysis of the collected data. The radial and vertical distribution of cesium (&lt;sup&gt;137&lt;/sup&gt;Cs) in trees was investigated. &lt;sup&gt;137&lt;/sup&gt;Cs has contaminated forest ecosystems by remote atmospheric transport and radioactive precipitation as a result of nuclear test including the nuclear accident in Chernobyl. On a longer time scale, the variability of the &lt;sup&gt;137&lt;/sup&gt;Cs distribution determined in the organisms of the silver fir depended on the half-life, while the seasonal dynamics were influenced by the degree of physiological activity and the characteristics and functions of plant tissues. The highest activity of &lt;sup&gt;137&lt;/sup&gt;Cs was determined in the bark and the physiologically most active parts of the silver fir (shoots and needles). The highest activity concentration of the &lt;sup&gt;137&lt;/sup&gt;Cs in the growth rings was measured in the lowest parts of the silver fir trees. This research contributed to understanding the behavior of &lt;sup&gt;137&lt;/sup&gt;Cs, which entered the organisms of dominant tree species in the forest ecosystem, as well as its distribution in time and space.
