摘 要:目的:建立马钱子士的宁和马钱子碱的含量测定方法,评价砂烫法与烘烤法对二者含量的影响。方法:分别制备砂烫马钱子和烘烤马钱子,采用高效液相色谱法测定士的宁和马钱子碱含量,以C18柱为固定相,乙腈(A):水-乙酸-三乙胺(230∶2.4∶0.4)(B)=11∶89为流动相,检测波长为254nm。结果:以200℃烘烤马钱子30分钟,士的宁和马钱子含量水平与砂烫马钱子水平相当。结论:砂烫马钱子炮制过程温度、时间对生物碱含量影响较大,而烘烤马钱子工艺可控性更强,用来控制马钱子质量优势显著。Objective: A HPLC based method was established for strychnine and brucine of Nuxvomica, to find the difference between Nux vomica of stir - frying with sand and baking Nuxvomica. Methods: Make two different kinds of Nuxvomica decoction pieces. The analysis was carried out on C ls column by HPLC with acetonitrile (A) :water - acetic acid - triethylamine (230:2.4:0.4) ( B ) = 11:89 as mobile phase, the detection wavelength was 254 nm. Results: The result shows that the level of strychnine and brucine in sand scalding Nuxvomica, equal to baking ones. Conclusion: As temperature and time is difficult to control for sand scalding Nuxvomica, baking Nuxvomica can be easily controled during Drocessing in actual production
