| titleOfInvention | Method for extracting dendrobine from dendrobe |
| abstract | The invention provides a method for extracting dendrobine from dendrobe. The method comprises the following steps: selecting reasonable macroporous resin to adsorb and an eluant to elute to obtain a relatively pure product; and finally, carrying out low-temperature crystallization by using a dilute hydrochloric acid solution to further purify the product so as to obtain high purity dendrobine, wherein the product is detected by virtue of high performance liquid chromatography, and the content of the obtained product is over 92%. The method provided by the invention is simple in process operation and the used raw materials and reagents are low in price, so that the safety is high. |
