Method for preparing oridonin |
| abstract |
The invention relates to a purification method for preparing oridonin, and specifically relates to a method and process for preparing high-pure oridonin. Oridonin is separated and purified by using reverse-phase silica gel or a reverse-phase polymer resin as a filler for a DAC preparation column and a mixed solvent of methanol and water as a mobile phase. A separation process is simple; extraction rate is high; the purity of a product is high; no pollution is caused; and a foundation is provided for further large-scale separation and purification of oridonin by using the preparative liquid chromatography. |
