摘要
目的 测定断血流中主要成分断血流皂苷A的含量。方法 采用反相高效液相色谱法。色谱柱DISCOVERY C18(4.6mmx250mm,5μm),流动相为甲醇-水(73:27),流速0.8ml/min,检测波长250nm。结果断血流皂苷A在15.0—39.0μg。ml^-1范围内呈良好的线性关系,平均加样回收率为98.5%,RSD为1.3%(n=9)。结论 本方法简便、快捷,重现性好。
Aim To establish a quantitative method for determination of dinodiside A in Clinopodium herb. Methods High performance liquid chromatography (HPLC) was employed for detemination. The sample, extracted with refluxing ethanol and columnied by macropore resin, was separated on DISCOVERY Cls Column(4.6ram × 250ram, 5μm), with a mobile phase consisting of methanol and water(73:27), a velocity of 0.8ml/min, a detecting wavelength at 250nm. Resuits Within the range of 15.0 - 39.0μg·ml^-1 of clinodiside A,the calibration curve was linear( r = 0.999 8).The mean recovery rate was 98.5 %, RSD = 1.3 % ( n = 9). The content of clinodiside A in Clinopodium plants was 0.03 % - 0.07%. Conclusions The method was very stable, accurate, and can be used as a quality standard for Clinopodium herb.
