Determination of Geniposide in Jinzhi Jieyin Gargle By RP - HPLC / 广州中医药大学学报

ABSTRACT

[Objective] To establish a method for the determination of geniposide in Jinzhi Jieyin Gargle by RP- HPLC. [ Methods ] SupelcosilTM LC - 18 (150 mm ?4.6 mm, 5?m) was used as the analytical column, methanol - water -phosphoric acid (25∶75∶0.12 ) as mobile phase and the detection wave - length at 240 run. [Results] Within the range of 0.175-1.84?g, geniposide showed a good linearity ( r = 0.9999 ). The average recovery was 99.93%(n=5, RSD = 1.16%). [Conclusion] This method can be used for the quality control of Jinzhi Jieyin Gargle.
