Alltesta HPLC Method for Tyramine on Primesep 100 by SIELC Technologies
High Performance Liquid Chromatography (HPLC) Method for Analysis of Tyramine
Tyramine is a naturally occurring compound derived from the amino acid tyrosine. It is found in various foods and beverages, especially aged or fermented products such as aged cheeses, cured meats, certain wines, and soy products. Tyramine can affect the release of norepinephrine, a neurotransmitter, and can influence blood pressure.
For people taking monoamine oxidase inhibitors (MAOIs), consuming foods high in tyramine can cause a dangerous spike in blood pressure, known as a hypertensive crisis. This is why individuals on such medications are often advised to follow a low-tyramine diet.
Tyramine can be retained, and analyzed using a Primesep 100 mixed-mode stationary phase column. The analysis utilizes an isocratic method with a simple mobile phase consisting of water, acetonitrile (MeCN), and sulfuric acid as a buffer. Detection is achieved using UV at 275 nm

High Performance Liquid Chromatography (HPLC) Method for Analysis of Tyramine
Tyramine is a naturally occurring monoamine compound that belongs to the class of biogenic amines. It is derived from the amino acid tyrosine and is found in various foods. Tyramine is particularly known for its potential role in certain food sensitivities and interactions with monoamine oxidase inhibitors (MAOIs), a class of medications.
Occurrence: Tyramine is present in foods that undergo fermentation or aging processes, such as aged cheeses, fermented soy products, certain wines, and cured or smoked meats.
Biological Role: It is a trace amine and has been studied for its potential physiological effects, including its role as a neurotransmitter and its impact on blood pressure regulation.
Food Sensitivities: Some individuals may be sensitive to tyramine, and excessive intake in susceptible individuals can lead to symptoms such as headaches, increased blood pressure, and other adverse reactions.
Interaction with Medications: Tyramine is notable for its interaction with MAOIs, a class of antidepressant medications. In individuals taking MAOIs, the consumption of foods high in tyramine can lead to a hypertensive crisis.
Metabolism: In the body, tyramine is metabolized by the enzyme monoamine oxidase (MAO). Inhibition of MAO can lead to increased levels of tyramine, contributing to its potential interactions with medications.
Tyramine can be retained and analyzed using a Primesep 100 mixed-mode stationary phase column. The analysis employs an isocratic method with a simple mobile phase comprising water, acetonitrile (MeCN), and sulfuric acid as a buffer. This method allows for detection using UV at 222 nm

Separation of Tyramine on Newcrom R1 HPLC column
February 16, 2018
Tyramine can be analyzed by this reverse phase (RP) HPLC method with simple conditions. The mobile phase contains an acetonitrile (MeCN), water, and phosphoric acid. For Mass-Spec (MS) compatible applications the phosphoric acid needs to be replaced with formic acid. Smaller 3 µm particles columns available for fast UPLC applications. This liquid chromatography method is scalable and can be used for isolation impurities in preparative separation. It also suitable for pharmacokinetics.
Application Column
Newcrom R1
The Newcrom columns are a family of reverse-phase-based columns. Newcrom A, AH, B, and BH are all mixed-mode columns with either positive or negative ion-pairing groups attached to either short (25 Å) or long (100 Å) ligand chains. Newcrom R1 is a special reverse-phase column with low silanol activity.
