摘 要:目的:考察不同加工方法对茯苓及茯苓皮中茯苓酸含量的影响。方法:采用高效液相色谱法测定各种不同茯苓加工品中茯苓酸的含量,采用Apollo C18色谱柱(250 mm×4.6 mm,5μm),以乙腈-0.5%磷酸水溶液为流动相,流速:1.0 ml·min-1,检测波长:210 nm,柱温:30℃。结果:茯苓皮中茯苓酸的含量>茯苓,且经蒸制后两者的含量均明显降低,其中生切品>传统法蒸品>高压蒸品。结论:茯苓酸对热压不稳定,茯苓经过蒸制后,其含量降低。本研究可为茯苓饮片的规范化加工炮制和质量控制提供参考。Objective: To compare the effects of different processing methods on the contents of pachymic acid in white poria and poria peel. Methods: An HPLC method was used on an Apollo Cls column(250 mm ×4.6 mm,5 μm) with acetonitrile4). 5% phos- phoric acid as the mobile phase, the flow rate was 1.0 ml · min-1 ,the column temperature was at 30℃ ,and the detection wavelength was at 210 nm. Results: The pachymic acid content in poria peel was higher than that in white poria, both of them were reduced obvi- ously after steaming, and the order was raw product 〉 traditional steamed product 〉 high pressure steamed product. Conclusion: Af- ter poria is steamed, pachymic acid cant keep stable under heat and pressure, and the higher the thermal pressure, the lower pachymic acid. The paper can be served as a scientific proof to standardize the processing and quality control of poria.
