Abstract:
Objective: To study the influences of steam distillation (SD) on the isomerization of the essential oils of Angelica sinensis (Oliv.) Diel. Methods: SD、GC、GC-MS. Results: The duration of the extraction of essential oils of Angelica sinensis (Oliv.) Diels. by SD was about 14 h, and the yield of (Z)-ligustilide was about 67.1 percent of total (Z)-ligustilide. During the SD, it produced some new components in the essential oils, for example 4-hydroxy-3-methylacetophenone, 2,4,5-benzaldehyde,2,4,5-trimethyl-et al. Conclusion: The results suggested that the extraction of essential oils of Angelica sinensis (Oliv.) Diels. by SD had some disadvantages.
