| titleOfInvention | Method for separating and preparing Brazilin and Protosappanin B from Sappanwood by using high-speed countercurrent chromatography |
| abstract | The invention discloses a method for separating and preparing Brazilin and Protosappanin B from Sappanwood by using high-speed countercurrent chromatography, which comprises the following steps: preparing a sample solution firstly, then carrying out separation and preparation on the sample solution by using a high-speed countercurrent chromatographic instrument and an ultraviolet detector, respectively collecting flow elements containing target components according to an ultraviolet map, and carrying out decompression concentration on the flow elements until the target components including Brazilin and Protosappanin B are obtained, wherein the nature determination of the target components is determined by a mass spectrum in combination with H nuclear magnetic resonance and a carbon spectrum, and the purity is determined by HPLC. According to the invention, a solid phase carrier is not required to be used, reversible adsorption does not exist, solvents used in the process of separation and preparation can be greatly reduced, the solvent reduced amount is over 80%, the separation time is saved by at least five times, and the yield is increased by more than 50%; separated target components are little in loss, high in purity, low in cost and economic and has environmental-friendly effect. |
