Optimization of Extracting Conditions of Nutmeg by Uniform Design

Objective To optimize the most favorable extraction conditions of Nutmeg. Method With the volatile oils extracting ratio of Nutmeg as optimization targets, the extraction factors affected the volatile oils extracting ratio were optimized by uniform design. Result The optimum condition for extraction was as follows:medicinal materials which screen mesh were 4～10, being soaked in 14 times water for 1 hours and distilled for 6 hours with vapour. Conclusion The extraction process of optimization is simple and practicable, and can provide the test foundation for production.
