摘要
本文通过溶剂法和超声法对山茱萸中总皂甙的提取工艺进行了研究,以提取温度、提取时间、95%乙醇用量等为因素,选用L16(43×26)和L9(34)正交表进行试验。结果表明,超声波的提取效率高于溶剂提取,大大缩短提取时间,优化工艺条件是:提取温度为85℃,提取时间为120min,95%乙醇用量为50ml。在此条件下,总皂甙的提取效率较高,其水解产物人参二醇含量可达5.16mg/g。
This paper studied the extraction of TGCO from Cornus officinalis Sieb. et Zucc. by either solvent or ultrasonic wave. Orthogonal test tables L16(43×26) and L9(34) were used with the optimum factors of extracting temperature, extracting time, 95% ethanol volume, etc respectively. The results showed that ultrasonic wave extraction was more efficient than the solvent extraction and shortened the extracting time largely. The optimum conditions were as follows: extracting temperature 85℃, extracting time 2 hours and 95% ethanol volume 50ml. Under the conditions, an extract with panaxadiol (hydrolysate of TGCO) as high as 5.16mg/g was obtained.
