摘要
目的研究地黄中梓醇的积累分布规律。方法高效液相色谱（HPLC）法，流动相：乙腈-水（0．5：99.5）；检测波长：210nm。结果标准曲线为：Y=347．93X＋10．138（r=0．9996），梓醇在0．3224～2，9016μg时呈良好的线性关系；平均回收率为96．21％，RSD为1．35％（n=5）。结论地黄中不同部位梓醇的积累分布具有一定的规律，值得进一步研究。
Objective To study the collective regulations of catalpol in different parts of Rehmannia glutinosa Libosch. Methods HPLC method was used the Mobile phase was cetonitrile - water （ 0. 5 ： 99. 5 ） and detection wavelength was 210 nm. Results The standard curve of catalpol was Y = 347.93X ＋ 10. 138 （ r = 0. 999 6） with the linear range of 0.322 4 ～2. 901 6 μg, the average recovery was 96.21% （ n = 5 ）. Conclusion The method is simple, sensitive and rapid, and collective regulations of catalpol in different parts of Rehmannia glutinosa Libosch are apparent.
