| 摘 要： | 采用水浴加热法、超声法和微波法等3种方法提取黄精总皂苷.结果表明:超声法提取黄精总皂苷方法最佳,具有高效、安全、成本低等优点,且能保护被提取成分不被破坏.采用超声提取,以人参皂苷Rb1标准品为指标,通过正交实验确定最佳提取温度、料液比和提取时间.结果表明:提取温度对黄精总皂苷提取有极显著的影响,提取时间和料液比影响不显著.确定最优提取工艺为:超声提取,80 %乙醇提取2次,提取温度60 ℃,提取时间50 min,料液比1∶15,提取总皂苷含量在3.4 %以上.

| Abstract: | A comparative investigation was carried out on the extraction of saponins from Polygonatum sibiricun with three methods: hot water bath refluxing,ultrasonic wave aided extraction,and microwave aided extraction.Ultrasonic wave aided extraction was selected as an optimal method with the advantages of efficiency,safty,low cost,and non-damage of saponins.Using the content of ginsenoside Rb1 as an indictor,the optimal ultrasonic wave aided extraction conditions were determined as: solvent: 80 % ethanol,times of ... |
