dG (Alfa Aesar), sodium persulfate (Na2S2O8; Sigma-Aldrich), sodium perchlorate (NaClO4; Sigma-Aldrich), 2′-deoxycytidine (Sigma), and lithium chloride (LiCl; Aladdin) were used as purchased without further purification. The DNA oligonucleotides (GC)6 and (GTGC)3 were purchased from Sangon Biotech (Shanghai) Co. Ltd. in the polyacrylamide gel electrophoresis–purified form. Single-strand concentrations were determined by monitoring the absorbance at 260 nm in the UV-Vis spectra and using the corresponding extinction coefficients of 101,100 and 107,400 M−1 cm−1 for (GC)6 and (GTGC)3, respectively. The sample of dG or the DNA oligonucleotide was dissolved in solution of LiCl (7.0 M) in H2O. The dsDNA oligomers in homogeneous aqueous glasses (7.5 M LiCl) have been reported to be in the B conformation (12 (link)). Thus, in our system (homogeneous solutions of oligomers in 7.0 M LiCl), the self-complementary oligomers (GC)6 formed a dsDNA conformation. Ultrapure water obtained by Millipore filtration was used as solvent. A total of ~120 or 20 mg of Na2S2O8 was added as the precursor of the initial oxidation radical, which triggered subsequent reactions.

The chemicals used were as follows: thymol (THY), ≥99.5%, carvacrol (CAR), ≥98%, sodium perchlorate NaClO4, anhydrous, p.a. (all Sigma-Aldrich, St. Louis, MO, USA). Glacial acetic acid, CH3COOH (HAc), p.a. ACS and acetonitrile CH3CN (AN), p.a. (both Merck, Darmstadt, Germany) or their mixture were used as solvents in all electrochemical experiments. Acetonitrile with GC grade, purchased from VWR (Radnor, PA, USA), was used in the chromatographic analysis. All reagents and solvents were of high purity and used as received.
The samples of rosemary, thyme, oregano, savory, herbes de Provence (all Kamis S.A., Stefanowo, Poland) were in a dry form.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
