摘要
目的用大孔树脂分离纯化刺五加苷的2种主要成分作为控制刺五加药材质量的标准。方法用D-101大孔树脂对刺五加苷B、刺五加苷E进行分离纯化,用高效液相色谱法测定以上2个成分的含量,以此作为刺五加的质量标准。结果上样液浓度0.5g·mL^-1,吸附流速2BV·h^-1,30%乙醇的洗脱流速1BV·h^-1。透析袋处理。色谱柱:C18(4.6mm×250mm,5μm);检测波长220nm;流动相:水-乙腈(0-10min,90:10;10-30min,90~80:10~20);流速:1.0mL·min^-1;柱温25℃。结论该方法操作性强,重现性好,可作为刺五加药材质量控制的有效方法。
Objective To purification the Acanthopanax glycosides of two kinds of main component with macroporous resin method to be control the standard of quality of Aeanthopanax medicinal materials. Methods Eleutheroside B and Eleutheroside E were isolated and purified by macroporous resin. Determination of Acanthopanax senticosus Harms of Eleutheroside B and Eleutheroside E content by HPLC, as a quality standard of Acanthopanax senticosus. Results The sample concentration is 0. 5 g · mL^-1, adsorption velocity 2 BV · h^-1, 30% ethanol eluent, elution rate 1 BV · h^-1. Dialysis treatment. Column: C18(4.6mm×250mm,5μm) ; detection wavelength was 220 nm ; mobile phase : water - acetonitrile (0 - 10 min, 90:10;10 -30 rain,90 -80:10 -20) ; flow rate: 1.0 mL ·min^-1 ; Column temperature was 25 ℃. Conclusion The method of operation has good reproducibility which can be used as an effective method to control the quality of Aeanthopanax senticosus harms.
