目的:优选没药挥发油的最优提取工艺条件。方法:以挥发油提取量为考察指标,选用挥发油轻油提取器加二甲苯提取挥发油,以浸泡时间(A)、粉碎目数(B),提取时间(C)、加水量(D)为考察指标,用U6(64)均匀设计进行优选。结果:优选工艺为没药粉碎过10目筛,加8倍量水,浸泡10 min,提取3 h。结论:提取的没药挥发油计量准确,工艺合理,为没药挥发油的提取研究提供了科学依据。 Objective: To optimize the extraction process of myrrh volatile oil. Methods: Taking the amount of volatile oil as the index, the essential oil was extracted with volatile oil extracted with xylene to extract the essential oil. The soaking time (A), crushing number (B), extraction time (C) and water addition (D) , U6 (64) uniform design is preferred. Results: The preferred process was myrrh crushed 10 mesh sieve, add 8 times the amount of water, soak 10 min, extraction 3 h. Conclusion: The extracted volatile oil of myrrh is accurate and the technology is reasonable, which provides a scientific basis for the extraction of the volatile oil of myrrh.
