Rhaponticin Analysis Service

Online Inquiry


Rhubarb is one of the traditional medicines commonly used to treat constipation, inflammation and cancer. The main purgative components of genuine rhubarb are senoside and anthraquinone glycoside. Compared with the genuine rhubarb, the non-genuine rhubarb has lower anthraquinone content and does not contain sennatin. The non-genuine rhubarb contains high content of rhaponticin, which can reduce the level of sugar and fat in the blood and is used to treat hyperlipidemia, obesity and diabetes. Generally speaking, rhaponticin should not be detected in genuine rhubarb. However, there exists the phenomenon of replacing genuine rhubarb with non-genuine rhubarb in practice, which affects the efficacy. It is of great practical significance to establish a method for the analysis and detection of rhaponticin. Creative Proteomics provides the simple, rapid, accurate, affordable and highly automated analytical method and equipment to analyze rhaponticin. High performance liquid chromatography (HPLC) can solve some of the problems associated with rhaponticin analysis. This analysis method is very simple, fast, accurate and reproducible. Improved extraction and purification steps can also increase the sensitivity of the analytical method.
