目的:优选黄蜀葵花中金丝桃苷的提取工艺。方法:以金丝桃苷的含量为考察指标,采用正交试验法对影响提取效率的主要因素进行优化。结果:最佳提取条件为10倍70%乙醇提取2h 1次。结论:优化的提取工艺简便、合理,为黄蜀葵花提取物的制备提供了一定的理论参考依据。
Objective: To optimize the extraction process of Hypericum periwinkle. Methods: Based on the content of hyperoside, orthogonal test was used to optimize the main factors affecting the extraction efficiency. Results: The best extraction conditions were 10 times 70% ethanol extraction 2h 1 times. Conclusion: The optimized extraction process is simple and reasonable, which provides a theoretical reference for the preparation of extracts of Abelmoschus.
