摘要:

目的:建立玉米须中刺芒柄花素含量测定的方法。方法:运用高效液相色谱法测定,色谱柱为HypersilC18 (4.6mm × 250mm,5μm),流动相为甲醇-0.1% 磷酸(55:45,V/V),流速0.8ml/min;检测波长254nm。结果:刺芒柄花素在2.3~23μg/ml 范围内线性关系良好,r=0.9991。平均回收率为96.93%,RSD 为1.30%。结论:本法方便、准确,可以用于玉米须的质量控制。

Abstract:

Objective: To develop an HPLC method for the determination of formononetin in corn silk. Method: Analysis was carried out by using Hypersil C18 (4. 6 mm ×250 mm, 5 μm) column with CH3OH-0.1% H3PO4 (55:45, V/V) as the mobile phase. The flow rate was 0.8 ml/min and the UV detection wavelength was set at 254 nm. Results: There is good linear relationship between integral value (Y) of peak area and formononetin reference substance concentration (X) in the range of 2.3 to 23μg/ml (r = 0.9991). The average recovery of formononetin is 96.93% with the RSD of 1.30%. Conclusion: The method is convenient and accurate, and can be used for the quality determination of corn silk.

Key words: corn silk, formononetin, HPLC
