目的:测定并比较不同产地亚贡叶中总酚酸的含量。方法:利用紫外可见分光光度法通过测定吸光度计算不同产地亚贡叶中总酚酸的含量。结果:不同产地亚贡叶中总酚酸的含量有所差异,产于辽宁鞍山的亚贡叶中总酚酸含量最高,本溪的亚贡叶总酚酸含量次之,一般含量不应少于4.00%。结论:亚贡叶中总酚酸的含量测定可作为亚贡叶的质量控制指标之一。 Objective: To determine and compare the content of total phenolic acids in Aconitum leaves from different areas. Methods: The content of total phenolic acids in Aconitum leaves of different habitats was calculated by measuring the absorbance by UV-Vis spectrophotometry. Results: The contents of total phenolic acids in Ya Gong leaves of different producing areas were different. The content of total phenolic acids in Ya Gong leaves produced in Anshan of Liaoning Province was the highest. The content of total phenolic acids in Ya Gong leaves of Benxi was the second, and the content should not be less than 4.00%. Conclusion: The determination of total phenolic acids in Ya Gong leaves can be used as one of the quality control indicators of Ya Gong leaves.
