Creative Proteomics provides high performance liquid chromatography (HPLC) based methods for liquiritin analysis, which provides sufficient stability, sensitivity and high resolution for identification and quantification of liquiritin. This approach has the advantages of simple, stable, fast, accurate, specific and reproducible, which can help researchers to analyze liquiritin effectively.


Liquiritin exists in the root of licorice, a leguminous plant. Liquiritin is an important monomer active component in licorice flavonoids, and is an important index for the quality control of licorice medicinal materials and their preparations. Liquiritin is a white powder soluble in methanol, ethanol, hot water and slightly soluble in ethyl acetate. Liquiritin is 100 to 500 times sweeter than sucrose. The sweetness is slow and lasts a long time. When used as sweet taste improver or enhancer, it is usually used in combination with other sweeteners. Clinically, licorice flavonoids have the function of scavenging free radicals, anti-oxidation, anti-cancer promotion and anti-protrusion. Because liquiritin has a wide range of uses, it is very important to establish the method for the analysis of liquiritin in plant metabolites. Creative Proteomics provides the simple, rapid, accurate, affordable and highly automated analytical method and equipment to analyse liquiritin. High performance liquid chromatography (HPLC) can solve some of the problems associated with liquiritin analysis. Improved extraction and purification steps can also increase the sensitivity of the analytical method.
