摘 要:目的:建立反相高效液相色谱法分离和测定龙血竭中紫檀芪的含量。方法:以Phenomenex C_(18)反相键合硅胶色谱柱(250 mm×4.6 mm,5μm),乙腈-1%冰醋酸(41:59)为流动相,流速1.5 mL·min^(-1),检测波长为310 nm,灵敏度为0.02 AUFS;柱温40℃;用外标法定量。结果:紫檀芪在41.6~208 ng范围有良好线性关系,r=0.999 5,理论塔板数以紫檀芪计为5 422;方法回收率为97.82%。结论:本方法是测定龙血竭中紫檀芪含量的准确、可靠、简便的定量方法。Objective: To establish a HPLC method for the separation and determination of pterostilbene in Drag-on's Blood. Methods: Using Phenomenex C18 reverse phase column (250 mm × 4. 6 mm, 5 μm) and acetoni-trile - 1% acetic acid (41 = 59) as mobile phase, flow rate of 1. 5 mL · min-1 , detecting at 310 nm and the sensitivity at 0.02 AUFS, the temperature of column was 40 ℃ and quantitating with external standard method. Results: The standard curve of pterostilbene was linear in the concentration range of 41. 6 -208 ng ( r = 0. 999 5). The theoretical plate number was 5 422. The average recovery was 97. 82% . Conclusion: The established method was accurate, sensitive, simple and reliable for determination of pterostilbene in Dragon's Blood.
