HPLC Separation of Uracil, Thymine, Hypoxanthine and Guanine on Newcrom AH

October 31, 2023

HPLC Method for Analysis of Uracil, Thymine, Hypoxanthine, Guanine on Newcrom AH Column by SIELC Technologies

Separation type: Liquid Chromatography Mixed-mode

High Performance Liquid Chromatography (HPLC) Method for Analyses of Uracil, Thymine, Hypoxanthine and Guanine

Uracil, Thymine, Hypoxanthine, and Guanine are all nitrogenous bases, each playing distinct roles in the biochemistry of nucleic acids.

Uracil (U):

  • Found in: RNA
  • Pairs with: Adenine (A)
  • Structure: Pyrimidine
  • Role: Uracil replaces thymine in RNA. In DNA, adenine pairs with thymine, but in RNA, adenine pairs with uracil.

Thymine (T):

  • Found in: DNA
  • Pairs with: Adenine (A)
  • Structure: Pyrimidine
  • Role: Thymine is specific to DNA, distinguishing it from RNA. It’s the base that pairs with adenine through two hydrogen bonds.

Hypoxanthine:

  • A naturally occurring purine derivative. It’s not directly a base in standard DNA or RNA, but it plays a significant role in the metabolism of purines.
  • It is the base form of the nucleoside inosine, which can be found in certain tRNAs and plays a role in wobble base pairing.
  • Hypoxanthine is also an intermediate in the purine degradation pathway, leading to the production of uric acid.

Guanine (G):

  • Found in: Both DNA and RNA
  • Pairs with: Cytosine (C)
  • Structure: Purine
  • Role: Guanine is one of the four main nucleobases in the nucleic acids DNA and RNA. It forms three hydrogen bonds with cytosine, contributing to the stability of the nucleic acid structures.

These nitrogenous bases are crucial for the structure, replication, and function of nucleic acids. Understanding their properties and interactions is fundamental to molecular biology and genetics.

Nucleotides can be retained and analyzed on a mixed-mode Newcrom AH column with a mobile phase consisting of water, Acetonitrile (MeCN), and ammonium formate. This analytical method can detect compounds with high resolution and peak symmetry using UV detection at 260 nm

HPLC Separation of Uracil, Thymine, Guanine, Cytosine, Adenine on Newcrom AH Column_1245

Uracil, Thymine, Guanine, Cytosine and Adenine are the nucleobases found in RNA and DNA.  The nucleobases are difficult to separate on reverse-phase columns due to their polar, hydrophilic and ionic nature.  Using the Newcrom AH mixed-mode column, the nucleobases can be easily separated isocratically using low organic mobile phase (5% acetonitrile) or pure water, if organic mobile phase is undesirable, with ammonium formate buffer, making the method both UV and Mass Spec compatible.

HPLC Separation of 8 Generic Compounds on Primesep Columns

March 27, 2011


Mixed-mode HPLC columns allow to analyze compounds with drastically different properties in one run. Acidic, basic, and neutral compounds can be separated in one run using either isocratic or gradient conditions. In this application, neutral hydrophilic (uracil, phenol and hydroquinone), neutral hydrophobic (toluene), hydrophilic acidic (benzoic acid), hydrophilic basic (lutidine) and hydrophobic basic (amitriptyline) are separated using gradient of ACN. Neutral compounds are retained by reversed-phase mechanism, hydrophilic acidic compound become more hydrophobic at lower pH and retain by reversed-phase mechanism too. Basic compounds are retained by cation exchange mechanism, and hydrophobic basic compounds are retained by reversed-phase and cation-exchange mechanisms. All compounds are resolved within 17 minutes on a short column. Method can be applied to various polar and hydrophobic compounds, which can be separated on one column and in one run. Mixed-mode columns can operate in single or combination of several modes: reversed-phase, ion-exchange, ion-exclusion and HILIC. This mixed-mode HPLC column can be used as a general column for separation of wide range of compounds.

HILIC Retention of Uridine and Uracil on Sielc’s HILIC Columns

August 22, 2008

Uridine and uracil are separated on three HILIC columns from SIELC. Primesep N, Primesep S, and Obelisc N columns all have different polarity and different embedded acidic groups on the surface of silica gel: Primesep N is a normal-phase HPLC column with embedded acidic groups with a pKa of about 5. Primesep S is a normal-phase HPLC column with embedded acidic groups with a pKa of about 3. The Primesep S stationary phase retains basic compounds by cation-exchange at pH > 3.

In traditional HILIC mode, a charged or neutral polar analyte interacts with a water layer on the polar stationary phase surface. On Obelisc N the charges are greatly separated and independently accessible, resulting in different selectivity compared to traditional HILIC and silica columns. Mobile phase composition changes the conformation of the long hydrophilic chain. All three columns can be used to analyze uridine and uracil by HPLC with UV, LC/MS and ELSD detection.

HPLC Application for Separation of Nucleotide Bases Uracil, Thymine, Guanine, Cytosine, Adenine on Primesep 200 Column

December 6, 2007

Nucleotide bases are parts of DNA and RNA. Adenine and guanine are purine-bases; uracil, thymine and cytosine are pyrimidine-bases. In the view of chromatography these compounds are very polar and similar in properties. It is hard to obtain base line HPLC separation on traditional C18 as peaks of nucleotide bases co-elute even at low organic concentration. In this application nucleobases are well retained and separated on Primesep 200 mixed-mode column. Compounds are retained by weak reverse phase and weak ion-exchange mechanisms. This HPLC method can utilize UV, ELSD, and LC/MS detection.
