XU Bing-bing, HUANG Bi-tao, ZENG Jin-xiang, et al. Comparison of Contents of Verbascoside and Isoverbascoside in Plantaginis Semen and Plantaginis Herba[J]. Chinese journal of experimental traditional medical formulae, 2016, 22(18): 64-67. DOI: 10.13422/j.cnki.syfjx.2016180064.
Objective: To analyze and compare the content differences of verbascoside and isoverbascoside in Plantaginis Semen and Plantaginis Herba
and provide experimental basis for quality control and clinical application of plantain. Method: A RP-HPLC method was applied for the content determination with a Diamonsil C18 column (4.6 mm×250 mm
5 μm) at 25℃. Methanol-0.1% formic acid aqueous solution(40:60) was used as mobile phase; the flow rate was 0.6 mL·min-1
and the detection wavelength was set at 330 nm. Result: Content of verbascoside in Plantaginis Semen was 9.70 mg·g-1 and 1.28 mg·g-1
respectively; and isoverbascoside was 0.32 mg·g-1 and 1.51 mg·g-1
respectively in Plantaginis Herba. Conclusion: Content of verbascoside in Plantaginis Semen was higher than that of Plantaginis Herba
while the content of isoverbascoside was below than that of Plantaginis Herba. The content differences shall be seriously considered in clinical application. It is recommended to add isoverbascoside as a mark component for the quality control of Plantaginis Semen and Plantaginis Herba.
