摘  要:
目的:研究优选薰衣草挥发油最佳提取工艺条件。方法:采用水蒸汽蒸馏法,正交试验考察了三因素(粉碎度、蒸馏时间、超声时间)三水平对其出油率的影响。结果:粉碎度和蒸馏时间是影响其挥发油出油率的主要因素,而超声时间对挥发油的提取影响并不明显,薰衣草挥发油的提取以粉碎度为40目以上,蒸馏时间为2h的效果最佳。结论:通过验证实验,表明所选的工艺条件可行。且挥发油蒸馏2h可提取完全,2h的平均出油率为(2.78±0.02)×10-2。

摘  要:
Object:To study and optimize the extracting technology conditions of the volatile oil of lavender.Method:Taking volume of volatile oil as index,the orthogonal test method was used for studying the effects of three extracting factors(the shape of the medicinal herbs,the distillating time,and the ultrasonic time)and three different levels of each factor on the volatile oil's yield of lavender.Result:The optimum conditions of the oil of lavender are:powder of 40-mesh,and distillating time 2h.Conclusion:The process is feasible and useful for new drug study on lavender,with average extracting rate of the volatile oil as(2.78±0.02)×10-2 。
