摘要
为了选出苦参中生物碱的最佳提取条件,本研究通过对比不同提取溶剂、不同提取方法对苦参中总生物碱出膏率、总生物碱含量的影响,并用酸性染料比色法测定药膏中总生物碱的含量。结果表明,氨水-氯仿提取,出膏率最高、总生物碱含量最高;超声提取高效、省时、省能源,是比较好的提取方法。
To find out an optimal extraction condition for sophora flavescens ait, the comparison of different extract solvents, extract methods on the paste-forming rate and total alkaloid content were developed. Total alkaloid content was measured by acidic dye colorimetric method. The results showed that both paste-forming rate and total alkaloid content were the highest when ammonia-chloroform was used as solvent. Ultrasound extraction was high efficiency, rapid and saving energy, and was the best extraction methods.
