摘要:目的 建立车前草中总苯乙醇苷和毛蕊花糖苷的含量测定方法。方法 采用紫外-可见分光光度法测定车前草中总苯乙醇苷含量。HPLC测定毛蕊花糖苷含量,色谱柱为ODS2 C18(4.6 mm×150 mm,5 ?m),流动相为乙腈-0.1%甲酸溶液(13∶87),流速为1 mL/min,检测波长为332 nm,柱温为30 ℃,進样量为10 ?L。结果 不同产地车前草中总苯乙醇苷含量范围为1.03%~3.47%;毛蕊花糖苷在0.006 2~1.55 mg范围内与峰面积呈良好的线性关系,加样回收率为98.9%(RSD=1.6%),不同产地车前草中毛蕊花糖苷的含量范围为0.18%~0.56%。结论 本研究建立的方法操作简单、稳定性好、重复性较好,可用于不同产地车前草中苯乙醇苷类成分及毛蕊花糖苷的含量测定,为车前草的质量控制提供了依据。

Abstract: Objective To establish a method for determination of phenylethanoid glycoside and acteoside in Plantago Herba. Methods UV-visible spectrophotometric method was used for the determination of the content of phenylethanoid glycosides compounds in Plantago Herba. HPLC method was used for the determination of acteoside in Plantago Herba. Chromatographic column with C18 ODS2 (4.6 mm × 150 mm, 5 ?m) was used. Acetonitrile-0.1% formic acid (13:87) was as mobile phase; the flow rate was 1 mL/min; the detection wavelength was 332 nm; the column temperature was 30 ℃; the sample volume was 10 ?L. Results The contents of phenylethanoid glycoside in Plantago Herba from different producing areas were among 1.03%–3.47%. Acteoside with peak area over the 0.0062–1.55 mg range showed a good linear relationship; the sample recovery rate was 98.9%, and the RSD was 1.6%. The contents of acteoside in Plantago Herba from different producing areas was among 0.18%–0.56%. Conclusion The method is simple, stable and reproducible, which can be used for the determination of phenylethanoid glycoside and acteoside in Plantago Herba from different producing areas and provide experimental basis for quality control of Plantago Herba.
