微波法优选乳香、没药挥发油的提取制备工艺

摘要

The extraction technology of volatile oil from Frankincense and Myrrh was optimized with microwave. Using the oil-bearing rate as the index, the microwave extraction technology was evaluated, and the study was carried out with orthogonal design to determine the optimum conditions. The optimum extraction conditions were adding 10-fold water into the mixture of Frankincense and Myrrh, and extraction for 10 min under microwave power 300 W with advanced soaking for 15 min. The technology was simple and practical and can keep the oil effectively and improve the stability of the drugs.%考察了微波法提取乳香、没药挥发油最佳工艺。采用正交实验设计法,以乳香和没药混合挥发油的提取率为评价指标,优选微波提取工艺。结果显示,挥发油的最佳提取工艺条件为：浸泡15 min,加10倍量水,微波功率为300 W,提取10 min。该工艺简单可行,可有效地保留挥发油,提高挥发油在制剂中的稳定性。
