摘要: 为获得贝母总生物碱的最佳提取工艺参数,以川贝母作为工艺参数研究对象,运用响应面试验设计探讨氯仿-甲醇比例、液料比、提取时间作为提取工艺考察的因素,以总生物碱为考察指标,用比色法测定不同基源贝母中总生物碱的含量,优化出贝母的最佳提取工艺,并比较不同基源贝母在该最佳工艺条件下总碱的含量差异。结果贝母总生物碱的最佳提取工艺参数为:混合溶剂(氯仿:甲醇)的比例为4.2:1,液料比为30:1,提取4 h。得到不同基源贝母中,湖北贝母总生物碱的含量最高,高达5.379 mg/g。本方法结果可靠、操作简便,优化后的最佳提取条件适合该药材的批量提取。

Abstract: In order to achieve the optimal processing conditions of alkaloids from Fritillariae bulbs. Fritillaria cirrhosa was firstly investigated. Response surface design were used to explore the extractive rate of the alkaloids through changing solvent ratio (CHCl3:CH3OH), liquid volume and the extraction time. The content was determined by colorimetry. Results indicated that the optimal extractive conditions were solvent ratio (CHCl3:CH3OH) of 4.2:1, liquid volume of 30, and extaction of 4 h. The maximum total alkaloids of 5.379 mg/g was from Fritillaria hupehensis under the optimal extractive conditions. This method is reliable, easy to operate. The optimized extractive conditions of should be the best for the extraction of the Fritillaria bulbs.
