Extraction Optimization of Volatile Oil in Myrrh by Uniform Design / 中国药师

ABSTRACT

Objective:To optimize the extraction technology of volatile oil in myrrh. Methods: Using the extraction quantity of volatile oil as the index, the volatile oil was extracted by an essential oil extractor, and U6 (64 ) uniform design was used to investigate the influencing factors such as the immersion time ( A) , the mesh number ( B) , the extraction time ( C) and the additive water amount ( D) . Results:The optimized extraction technology was as follows: myrrh was crushed to obtain 10 mesh powder, soaked for 10 mi-nutes with 8-fold amount of water, and then extracted 3 hours. Conclusion:The quantity of volatile oil extracted from myrrh is accu-rate, the technology is reasonable, and the research provides scientific basis for the extraction of volatile oil in myrrh.
