Patent Title: Novel Environmentally Friendly Technology for Production of Ginsenoside Re
Publication date: 2011
Publication number: US20110054155

Abstract: This invention relates to a technology used for a fast separation of Ginsenoside Re directly from other ginsensosides with similar molecular structures. In a conventional method, multiple steps and complex organic mobile phases are required to obtain a highly purified Ginsenoside Re compound, which are time consuming and organic solvent consumption, an obstacle for large scale industrial production. In our new technology, a quick separation for a mixture of two compounds with similar molecular structure. Ginsenoside Re and Ginsenoside Rg1 was demonstrated through a Surpass.TM. PolyGin-Re column 2.times.250 mm, in which only methanol was used for elution, no acids or bases were needed, which could be a Green technology for Ginsenoside Re production in the future.
