Webb15 nov. 2024 · The recovery for uracil, xanthine, cytidine, thymine, and adenosine were above 90%, while the recovery for others was lower. The results suggested that there were strong matrix effects from tea brews, especially for cytosine, adenine, guanine, hypoxanthine, uridine, guanosine, inosine, AMP, UMP, GMP, CMP, and IMP. Webb19 sep. 2024 · Guanine (G), adenine (A), thymine (T), and cytosine (C) are the four basic constituents of DNA. Studies on DNA composition have focused especially on DNA damage and genotoxicity. However, the development of a rapid, simple, and multiplex method for the simultaneous measurement of the four DNA bases remains a challenge.
