目的:优化枇杷花总黄酮提取工艺。方法:以总黄酮为考察指标,通过单因素及L9(34)正交试验优选枇杷花总黄酮的提取工艺。结果:确定以1∶10的料液比在60℃提取3次,每次1h为最佳提取条件。结论:本实验采用的方法和指标适合于枇杷花总黄酮的提取,为将其开发成为现代中药成方制剂提供了科学依据。
Objective: To optimize the extraction process of total flavonoids from Sophora japonica. Methods: The total flavonoids were used as indexes, and the extraction process of total flavonoids from Sophora japonica was optimized by single factor and L9 (34) orthogonal test. RESULTS: It was determined that a 1:10 ratio of material to liquid was used to extract 3 times at 60°C for 1 h each time as the best extraction conditions. Conclusion: The methods and indicators used in this experiment are suitable for the extraction of total flavonoids from Sophora japonica, which provides a scientific basis for its development into a modern prescription for traditional Chinese medicine.
