- 摘要:
- 为了建立洋金花种子中总生物碱的最佳提取工艺。比较冷浸法、超声法、回流法和索氏提取法的提取率;以乙醇浓度、提取时间、提取次数、料液比及pH为参数进行L16 (45) 正交试验;使用紫外分光光度法测定总生物碱及阿托品的含量。结果表明:回流法提取率最高;最佳提取工艺为无水乙醇回流提取2次,每次3 h,固液比1∶25,pH为5。乙醇浓度、固液比对生物碱的提取有显著影响;优选得到的提取工艺简单易行,稳定性良好。
- Abstract:
- In order to establish the optimize extraction technology of total alkaloid from seed of Datura.the extraction ratio of cold soak extraction,ultrasonic extraction,reflux extraction,and soxhlet extraction was compared; the extraction technology was optimized by L16 (45) orthogonal test with concentration of ethanol,duration of extraction,times of extraction ,solid-liquid ratio and pH as parameters,UV was adopted to detect the content of total alkaloids and atropine.The results showed that reflux extraction had the highest extraction ratio.The best extraction technology was as followd:reflux 3 hours with 2 times,solid-liquid ratio with 1:25,pH value with 5.Ethanol concentration and solid-liquid ratio had the significant impact on the extraction of alkaloids.This optimized extraction technology is simple,stable and feasible.
