Study on Optimal Extraction Technology for Volatile Oil in Radix Angelicae Sinensis
当归挥发油提取工艺的研究

This study was aimed to optimize the extraction of volatile oil in Radix Angelicae Sinensis. The L9(34) orthogonal design was carried out for the optimization of water extraction of volatile oil in Radix Angelicae Sinensis. And the content of volatile oil was used as reference index. The results showed that the optimal extraction process was as follows. Medicinal materials were crashed to go through mesh 10, then were soaked in 10-fold volume of water for 3 hours, and were extracted for 8 hours. It was concluded that the optimal extraction technology is simple and feasible with the extraction rate of volatile oil being 5.0%.
