| titleOfInvention | Method for separating and preparing lignan derivatives from biota orientalis |
| abstract | The invention relates to the technical field of natural medicinal chemistry, in particular to a method for separating and preparing lignan derivatives in platycladus orientalis. The preparation method comprises the following steps: the method comprises four steps of extraction, microporous resin enrichment, reversed phase C18 liquid chromatography separation and reversed phase phenyl column liquid chromatography purification separation. The technical means adopted by the invention can be used for large-scale production: the raw materials are widely planted, the cost is low, and batch preparation is easy; normal hexane is percolated and extracted at room temperature, so that the operation is easy; the separation adopts coarse separation of microporous resin, and the microporous resin separation material can be arranged in a medium-pressure column chromatography system and is easy to scale; the reversed-phase high-pressure preparation liquid chromatogram used in the separation and purification is a quick isocratic method and can ensure that the purity of the product is more than 98 percent. |
