目的:对贵州省不同产地半枝莲中总黄酮的含量进行分析,为黔产半枝莲的开发提供参考。方法:以野黄芩苷作为对照品,利用紫外-可见分光光度法在335nm下对十批半枝莲进行测定。结果:不同产地半枝莲总黄酮的含量差异显著。结论:产于贵州省中部、东南部及北部地区的半枝莲,其总黄酮含量较产于贵州省西南部及西部者高。
OBJECTIVE: To analyze the content of total flavonoids in Scutellaria barbata from different habitats in Guizhou Province, and to provide a reference for the development of Scutellaria barbata in Guizhou. Methods: Scutellaria baicalensis was used as a reference substance, and ten batches of Scutellaria barbata were determined by UV-Vis spectrophotometry at 335 nm. Results: The content of total flavonoids of Scutellaria barbata in different areas was significantly different. Conclusion: Scutellaria barbata, produced in the central, southeast and northern regions of Guizhou Province, has a higher total flavonoid content than those produced in the southwestern and western Guizhou Provinces.
