摘要
目的:建立有毒中药京大戟与甘遂生品、醋制品中大戟二烯醇的含量测定方法,并比较两者炮制前后的含量变化。方法:采用高效液相色谱法。色谱柱为Hypersil ODS(250mm×4.6mm,5μm),流动相为乙腈-水(98∶2),柱温为30℃,流速为1.0mL·min-1,检测波长为210nm。结果:大戟二烯醇进样量在0.42~6.23μg范围内与峰面积积分值呈良好线性关系(r=0.9998);京大戟和甘遂生品的平均加样回收率分别为99.28%和99.80%,RSD分别为1.69%和1.83%(n=9)。京大戟中大戟二烯醇的含量明显高于甘遂,且醋制不会对大戟二烯醇的含量造成显著影响。结论:本方法能准确测定京大戟和甘遂中大戟二烯醇的含量。
OBJECTIVE: To develop a method for the determination of euphol in unprocessed Euphorbia pekinensis and E. kansui and their vinegar-processed products, and to compare the changes of euphol before and after process. METHODS: HPLC method was adopted. Samples were analyzed on a Hypersil ODS(250 mm×4.6 mm, 5 μm) column with mobile phase consisted of acetonitrile-water (98:2) at a flow of 1.0 mL.min-1 and the detection wavelength was 210 nm. The temperature of column was 30 ℃. RESULTS: The linear range of euphol was 0.42-6.23 ug(r=0.999 8) and the average recovery of E. pekinensis and E. kansui was 99.28% and 99.80% with RSD of 1.69% and 1.83% (n=9), respectively. The content of euphol in E. pekinensis was higher than in E. kansui significantly. Vinegar process had no significant effect on the content of euphol. CONCLUSION: The method was accurate for the determination of euphol in E. pekinensis and E. kansui.
