Özet
Different methods are used for extracting phytochemicals from plant produce. Some rmethods require sophisticated and expensive instruments, while others need multiple steps rand specialist equipment, leading to an increase in energy, solvents, cost, and time. Here, the effect of incorporating hydrogen (H2) into solvents (that is water, ethanol, rmethanol) on the extraction of flavonoids (TFC), phenolics (TPC), anthocyanins rr(TAC), and antioxidants (DPPH and ABTS), as well as the extraction yield from red rbeetroot, were evaluated. The biggest extraction yield was with the use of H2-rich rmethanol (HRM) (24.32%). Incorporating H2 into water, ethanol, and methanol rled to a significant increase in TPC by 77.34%, 39.02% and 89.07%, in the TFC by rr43.30%, 50.5% and 88.87%, in the TAC by 92.62%, 199.5% and 257.41%. DPPH rscavenging activity increased by 6.49%, 7.05% and 12.15%, and ABTS scavenging ractivity by 3.93%, 9.82% and 15.05%, respectively. The extraction of individual rphenolic compounds, using various solvents, were different for each compound rinvestigated, with HPLC analysis showing that the levels of some phenolics increased rwhen H2 was incorporated into the solvents. rThis method, i.e., addition of H2 gas, is rsuggested as a relatively cheap and practical method for increasing the extraction of rphytochemicals using an eco-friendly method.
