目的建立RP-HPLC法测定天山雪莲药材中去氢木香内酯的方法。方法色谱柱为Symmetry ShieldTmMRP18(250mm×4.6 mm,5μm),流动相为甲醇-水(13∶7);体积流量为1.0 mL/min;柱温为30℃;检测波长为225 nm;进样量为10μL。结果去氢木香内酯线性范围为0.104 2μg~2.084μg,平均回收率为99.71%;RSD为0.98%(n=9)。结论本方法操作简单、灵敏、准确、重现性好,可用于天山雪莲药材的质量控制。
Objective To establish a RP-HPLC method for the determination of dehydrovaroxiboside in medicinal materials of Tianshan Saussurea. Methods The chromatographic column was Symmetry Shield TM M P18 (250 mm × 4.6 mm, 5 μm). The mobile phase was methanol-water (13: 7), the volume flow rate was 1.0 mL / min, the column temperature was 30 ℃, the detection wavelength was 225 nm. 10 μL. Results The linear range of DH was 0.104 2μg ~ 2.084μg, the average recovery was 99.71%; RSD was 0.98% (n = 9). Conclusion The method is simple, sensitive, accurate and reproducible. It can be used for the quality control of Tianshan Saussurea.
