    Polymethoxylated Flavone Analysis Service

      Polymethoxylated flavones, commonly referred to as PMFs, are a class of flavonoid compounds widely present in nature. They are mainly found in citrus fruits such as oranges and lemons. The prominent feature of these compounds is the presence of multiple methoxy (-OCH₃) groups in their molecular structure. Polymethoxylated flavones, due to their excellent antioxidant, anti-inflammatory, and anticancer properties, have attracted widespread attention in the fields of biochemistry, nutrition, and medical care.


      Services at MtoZ Biolabs

      MtoZ Biolabs offers comprehensive polymethoxylated flavone analysis services, including identification, quantification, purity assessment, sample preparation and extraction, customized analysis methods, comparative analysis, and stability and shelf-life studies. MtoZ Biolabs uses a variety of techniques for these analyses, including high-performance liquid chromatography-mass spectrometry (HPLC-MS), gas chromatography-mass spectrometry (GC-MS), liquid chromatography-tandem mass spectrometry (LC-MS/MS), quadrupole time-of-flight mass spectrometry (Q-TOF MS), and triple quadrupole mass spectrometry (QQQ-MS).


      Technical Principles

      Depending on the analysis needs, MtoZ Biolabs will choose the most appropriate analysis technique. For example, HPLC-MS, and LC-MS/MS are widely used for the separation and identification of polymethoxylated flavones, while GC-MS is more commonly used for the analysis of volatile compounds. Q-TOF MS and QQQ-MS can be used for the accurate mass measurement and targeted analysis of polymethoxylated flavones.
