Abstract:

In the present study, the simultaneous extraction technology of water soluble alkaloids and essential oil from Zanthoxylum bungeanum was optimized by L9(34) orthogonal test. The results showed that the optimal extraction conditions were as follows: soaked time of Zanthoxylum bungeanum seed in deionized water 2 h, pH 2, ratio of material to deionized water 1:15 (W/V), and extraction time 3 h. Under these conditions, the yields of water soluble alkaloids and essential oil were 4.36% and 3.25%, respectively.

Key words: Zanthoxylum bungeanum, water soluble alkaloids, essential oil, simultaneous extraction
