摘要
目的:优选姜黄提取工艺。方法:采用单因素法,以姜黄挥发油收率为评价指标,优选姜黄挥发油提取工艺条件;采用正交试验法,以姜黄素、干膏率为评价指标,优选姜黄醇提工艺条件。结果:姜黄挥发油提取工艺条件为:粉碎过一号筛,加8倍水,蒸馏提取7 h;姜黄醇提的工艺条件为:加80%乙醇,提取3次,每次加药材8倍量乙醇,提取60 m in。结论:优选的姜黄提取工艺条件稳定可行。
object： To optimize the extracting process of curcuma longa. Methods： With the recovery of volatile oil as the index, the extracting technology for volatile oil was optimized by single factor level test. The preparation process of curcuma longa was optimized by the orthogonal design, with the recovery of curcumins and soft extract as the index. Results： The optimum extraction condition for the volatile oil was adding 8 times amount of water to extract for 7 hours. The optimum condition for curcumins was adding 8 times of 80% alcohol to extract 3 times, once for 1 hour. Conclusion： The extraction process was stable and feasible.
