摘要(Abstract):

目的建立超高效液相色谱(UHPLC)法测定八宝惊风散中沉香四醇含量的方法。方法采用Agilent Poroshell 120 SBC18(100 mm×4.6 mm,2.7μm)为色谱柱固定相,以乙腈(A)-0.1%甲酸水溶液(B)为流动相,梯度洗脱,流速为0.8 mL·min~(-1);柱温为40℃;检测波长为252 nm。结果沉香四醇实现较好地分离,在4.02~40.2μg·mL~(-1)范围内线性良好(r=0.999 9);平均回收率为98.90%(n=6),RSD为1.64%。结论该方法测定结果准确可靠,重现性好,可以作为八宝惊风散质量控制的参考依据。
OBJECTIVE To establish a method for the determination of Agarotetrol in Babaojingfeng powder. METHODS The Agarotetrol was performed on a Agilent Poroshell 120 SB-C18( 100 mm × 4. 6 mm,2. 7 μm) column using a mobile phase of acetonitrile-0.1% formic acid in water; and the detective wavelength was 252 nm. RESULTS The calibration curve of agarotetrol were linear with the concentration range of 4.02-40.2 μg·mL~(-1)( r = 0.999 9).The accuracy was good with average recovery was 98.90%with RSD 1.64%,respectively. CONCLUSION This method is accurate,reliable and reproducible,it can be used for the quality control of Babao jingfeng powder.
