| Abstract: | The volatile oil of Zanthoxylum bungeanum Maxim (Dahongpao cultivar) was extracted with hot petroleum
ether. The extraction parameters were optimized using orthogonal array design to obtain maximum extraction efficiency of
volatile oil. The chemical constituents of the volatile oil were analyzed by gas chromatography-mass spectrometry (GCMS).
The results showed that the optimal extraction conditions determined were as follows: material to liquid ratio, 1:14
with petroleum ether (60–90 ℃) as extraction solvent; extraction temperature, 60 ℃, and extraction time, 3 h. A total of 52
compounds were identified by GC-MS, mainly including 6-octadecenoic acid (18.096%), 1-methyl-4-(1-methyl ethyl)-1,4
cycloheXadiene (11.462%), and palmitic acid (7.051%). |
