摘　　要：对酸性染料比色法来测定提取液的总生物碱的方法加以改进;并对以SFME法提取精油后的青花椒作原料、用不同浓度的乙醇渗漉法提取生物碱进行含量测定,确定乙醇渗漉法提取生物碱的相关工艺参数。结果表明：青花椒生物碱提取的最佳操作条件是控制渗漉液的流速在每秒2滴左右,每15 min收集约60 m L左右渗漉液,渗漉时间为2.5 h,乙醇浓度为70%~75%。This article determines the technological parameters of ethanol diacolation method for extraction of Chinese prickly ash alkaloids,improving the methods of acid dye colorimetry for alkaloids determination of extracting solution and determinating the contents of alkaloids extracted from the green prickley ash using ethanol of different concentrations which extracted essential oil by SFME. The results show that the optimum operating condition for extractiong of the green prickley ash alkaloids is two drops per second of diacolating liquid,collecting 60 m L diacolating liquid every fifteen minutes,2. 5 h of diacolation time and 70% ~ 75% ethanol concentration.
