摘 要:目的:测定白苏子和紫苏子生品及其不同炮制品中迷迭香酸的含量。方法:采用RP-HPLC测定迷迭香酸的含量,色谱柱:Welch C18(250 mm×4.6 mm,5μm)柱;流动相:甲醇-0.1%磷酸水溶液(39∶61);流速1.0 mL/min;检测波长330 nm;柱温28℃。结果:白苏子经炒制后迷迭香酸含量升高,单紫苏子和双紫苏子则相应降低;白苏子、单紫苏子和双紫苏子经蜜制、制霜后迷迭香酸含量均下降,蜜制品下降幅度更大。结论:苏子经加热处理后,迷迭香酸含量易下降。Objective:To determine the content of rosmarinic acid in seeds and its processed products of Perilla frutescens var.typica(PFT),Perilla frutescens var.acuta(PFA) and Perilla frutescens var.acuta form.discolor(PFAD).Methods: The content of rosmarinic acid was determined by RP-HPLC with Welch C18(250 mm×4.6 mm,5 μm) column,using methanol-phosphonic acid solution(39∶61) as mobile phase at flow rate of 1.0 mL/min.UV detection wavelength was set at 330 nm and column temperature was set at 28 ℃.Results: The content of rosmarinic acid in roasted seeds of PFT is higher than in its seeds,but that of PFA and PFAD are lower;The content of rosmarinic acid in seeds of PFT,PFA and PFAD decline after the seeds are honey-pocessed and made into frostlike powder,and that of honey-processed one decline by a larger margin.Conclusion: The content of rosmarinic acid in seeds of PFT,PFA and PFAD are prone to decline by heat-processing.
