“…However, many other herbs that are of scientific interest still demand description and further studies. Techniques and extracts are constantly being studied for different plant species, but each plant and each type of extract, such as lipophilic oils, peptides, polysaccharides, or antioxidants, all have particularities of chemical extraction processes, which brings complexity to the matter [6][7][8][9][10].…”

Plants are a core part of cultural identity, as part of a diet, decorations, ceremonies, or as medicinal agents. Empirical knowledge regarding plants and their healing potential has existed worldwide for centuries. With the advance of science and technology, not only is the refinement of such sources or isolation of specific compounds possible, but these compounds can also be characterized based on their natural occurrence. Besides their importance for plant metabolism and structure, polysaccharides have been demonstrated to have substantial positive human health impacts on inflammation, metabolism, oxidative stress, and others. As an inherent part of plant cell walls, many polysaccharides from medicinal herbs, such as fructans, glucans, and pectins, have been extracted and analyzed for their structure and function. However, a review summarizing a significant portion of these studies was still unavailable. This review helps to fill the knowledge gap between polysaccharide bioactivity, their structure, and their plant matrix sources, focusing on historical medicinal usage.

The objective of the present study was to assess the difference in antimicrobial activity of Satureja kitaibelii Wierzb. ex Heuff. essential oil at three growth stages. In addition, using statistical and chemometric tools, we tried to explain why the essential oil from a certain vegetation stage shows the highest antimicrobial activity. S. kitaibelii essential oils demonstrated minimum inhibitory concentration values from 160 to 10000 μg mL−1, and minimum microbicidal concentration values from 630 to 20000 μg mL−1. Geraniol, borneol, limonene and p‐cymene are the dominant compounds of S. kitaibelii essential oil. The most abundant compound, geraniol, possesses antimicrobial activity in a range of MIC values from 40 to 5000 μg mL−1 and MMC values from 80 to 10000 μg mL−1. The highest activity of essential oil for all tested strains of microorganisms was recorded in November. Results of statistical analysis indicate that the percentage of dominant compounds of essential oils does not affect the antibacterial activity of essential oils. Chemometric analyses leads to the conclusion that borneol, spathulenol, caryophyllene oxide and limonene can be the main contributors to the antibacterial activity of essential oil from November and that their mutual ratio is important. These results may represent a new methodological approach for future research on essential oils.
