Antioxidant Activity, Total Phenol and Total Flavonoid Contents of Trachystemon orientalis (L.) G. Don

Abstract

For many years, plants have been considered a source of alternative medicine and are used for the treatment of several diseases. These medicinal plants are excellent sources of phytochemicals and antioxidant activity. Trachystemon orientalis (L.) G. Don (Boraginaceae) originates from East Bulgaria but can be found mostly in West Caucasia and the Black Sea region of Turkey. Its flowering branches, rhizomes, and leaves are used as food. Materials and Methods: The antioxidant activity of a T. orientalis aqueous infusion was investigated using various antioxidant tests, such as reducing power and radical scavenging activity. The phenolic and flavonoid contents were also determined. Results were compared with natural and synthetic antioxidants. Results: The results demonstrated that T. orientalis (L.) is a good source of antioxidants. Conclusion: This study suggested that T. orientalis extract can be considered a useful natural antioxidant source because of its flavonoid, phenolic, and anthocyanin contents. The food and cosmetic industries might employ T. orientalis extract as an alternative additive to other highly toxic synthetic antioxidants.

Profile of fatty acids, vitamins, phytosterols and phenolic acids in Trachystemon orientalis L. and evaluation of their antioxidant activity

“…According to our results, although there are fluctuations in some concentrations, it can be stated that the radical scavenging activity of DPPH increased due to the increasing concentration of T. orientalis extracts. It is seen that there is similar potential in previous studies (Ayhan et al, 2019;Sacan, 2018). It is observed that there are significant changes in the DPPH radical scavenging activity of T. orientalis extract depending on the solvent.…”

“…The phenolic content of the aqueous extract of T. orientalis was reported to be 90 mg GAE/g in another investigation (Ayvaz, 2015).In a previous study, it was found that the total phenolic content equivalent to 36 µg of pyrocatechol was found in the aqueous infusion extract of the T. orientalis. In addition, in this study, it was determined that the anthocyanin level of the T. orientalis was equal to 0.35 µmol/g extract (Sacan, 2018).…”

“…It seems that there is no literature on the phenolic acid composition of this plant. Some studies have been conducted on the total amount of phenolic compounds (Ayvaz, 2015;Sacan, 2018;Ayhan et al, 2019). Therefore, important information about the phenolic acid content of this plant was obtained for the first time in this study.…”

Total Antioxidant Potential, Total Phenolic Profile and Cytotoxic Activity Against Brain Cancer: Melocan and Galdirik

“…This plant is considered edible since people in the Black Sea region use its flowers, rhizomes, leaves and petioles in different recipes. According to recent reports, galdirik contains anti-rheumatic, blood-purifying, diuretic, antipyretic and wound-healing properties ( 16 ). Additionally, large amounts of phenolic compounds, including tannin, saponin and choline have been found in galdirik in a number of studies.…”

Bio-augmentation of antioxidants and phenolic content of Lablab purpureus by solid state fermentation with GRAS filamentous fungi

“…Natural antioxidants tend to be safer and they also possess antiviral, anti-inflammatory, anti-cancer, antitumor and hepato-protective properties [10] . Natural antioxidants also protect the human body from the oxidative damage caused by free radicals [11][12][13] .…”
