The invention relates to a method for extracting active substances from a wolfberry, in particular to a method for extracting zeaxanthin and a derivative of the zeaxanthin from the wolfberry. The method comprises the steps of performing sugar reduction on the wolfberry, drying 10 kg wolfberry, grinding into 100 meshes, putting the wolfberry in a supercritical extraction kettle for extraction, merging and collecting an extract for 0.6-3 h to obtain the zeaxanthin and the derivative of the zeaxanthin. The method does not use an organic solvent in the whole process, and is safe and efficient, technical parameters are applicable to pilot-plant-scale production, and the purity reaches 80% or above. 本发明涉及种提取枸杞中有效物质的方法，尤其是涉及种提取枸杞中的玉米黄质及其衍生物的方法，该方法为先将枸杞降糖，然后取10kg烘干后粉碎至100目，置于超临界萃取釜中进行萃取，然后合并收集0.6h-3h萃取物，为所得玉米黄质及其衍生物；本发明提供种全过程无有机溶剂，安全、高效，且该技术参数适应于中试放大生产、并纯度达80%以上。
