“…4) Antioxidant activity of Aronia taxa is similar to that of wild-growing Sambucus nigra L.: a water extract from elderberry inflorescence was between 85.12% and 89.29%; in an alcoholic extract from fresh inflorescences, anti-radical activity was between 90.99% and 93.16% (Horčinová Sedláčková et al, 2018). This index is similar also to that of Diospyros virginiana, which has been used in folk medicine of North American Indians because of its high antioxidant activity (Grygorieva et al, 2018).…”

Useful wild plants usually decrease the content of biologically active substances in culture. However, there are no studies on the reverse process and no evidence whether the level of biologically active compounds increases in plants escaping from culture and becoming invaded in natural communities (invasive species). We studied Aronia melanocarpa, A. arbutifolia, A. × prunifolia, 2 samples of cultivated A. mitschurinii in the arboretum of the Main Botanical Garden (Moscow, Russia) and one sample of invasive A. mitschurinii from the Moscow region. The task of the study was to determine the degree of heritability of macro-and micromorphological characters of North American plants introduced to Europe. The identification of the samples most promising for further broad cultivation by their antioxidant activity and the content of microelements in leaves was also our Environmental Research, Engineering and Management 2018/74/4 44 research purpose. The diagnostic features of the introduced North American Aronia were found to be inherited under culture conditions. The mass of fruits increases in this order: A. arbutifolia → naturalised A. mitschurinii → A. × prunifolia → A. melanocarpa → cultivated A. mitschurinii. An original table was compiled to compare the studied taxa on 21 biomorphological features. Naturalising plants have a higher antioxidant activity of alcohol extracts than cultivated plants, and, on the contrary, lower antioxidant activity of water extracts. The leaves of A.

Persimmon which is widely known as "Trabzon Hurması" and "Cennet Meyvesi" is a very popular fruit with bright orange color. In the presented study, extractable, non-extractable, total phenolic content (TPC), antioxidant capacity (AC) and bioaccessibility of Trabzon persimmons (astringent, non-astringent and wild persimmon) were determined. The results of this study indicated that all types of persimmons have great importance both on TPC, AC and bioaccessibility. Compared to astringent and non-astringent types, the wild persimmon type had the highest TPC. Another attractive result from this study, although the wild persimmons do not prefer for consumption, the results demonstrated that the bioaccessible phenolics of this type of persimmons were found to be 6.7 fold higher than the non-astringent types and 4.7 fold higher than the astringent types. Especially the wild type of persimmon is a good source of natural antioxidant and further studies should be carried out for wild type persimmon.

Polyphenols are valuable group of phytoconstituents due to their high antioxidant activity and healing properties. Antioxidant properties of sages are attributed mainly to a high level of phenolic compounds. The aim of the present study was to elaborate an analytical procedure for the evaluation of the content of secondary metabolites of the polyphenol nature in the herb of Clary Sage (Salvia sclarea L.). Four crude extracts of Salvia sclarea herb obtained with different technologies were used to develop an analytical procedure for the total phenolic content (TPC) assay by spectrophotometric method. The optimum conditions for the analysis (time of the reaction, wavelength, and reference substances) were chosen and experimentally justified (60–80 min, 760 nm, gallic acid and rutin, respectively). Under these conditions, the developed analytical procedure is robust in the indicated time and easy for performing in phytochemical or technological laboratories. The yield of TPC from the herb of Salvia sclarea was the highest in the extracts prepared by heating at a temperature of 36–46 °C and with using the ultrasonic bath. TPC was the highest in the extract in which solvent-to-herb ratio was the least (10:1) and particle size was in the range of 2–5 mm. As a result of the studies, the analytical procedure of the determination of TPC was developed and its parameters were justified. This methodology complies with the requirements for pharmaceutical analysis to ensure the reliability of results during pharmaceutical development and routine control of Salvia sclarea extracts.
