[Objective] The study aims to optimize the extracting technology conditions of essential oil from Elsholtzia densa Benth. [Method] Essential oil was extracted from E. densa Benth using steam distillation, and the effects of four extracting factors (grain size of the medicinal herb, ultrasonic time, soaking time and ratio of the material to liquid) on the yield of essential oil extracted from E. densa Benth were analyzed through the orthogonal test. [Result] The optimized extraction process of essential oil from E. densa Benth was as follows: grain size of the medicinal herb 50 mesh, ultrasonic time 12 min, being soaked in the water for 6 h, and ratio of the material to liquid 1:16 g/ml. Under the conditions, the average extracting rate of the essential oil was 0.407%. [Conclusion] The optimized extraction process of essential oil from E. densa Benth was simple and practicable, and its extracting rate was higher. [ABSTRACT FROM AUTHOR] |
