Sterols and pentacyclic triterpenoids from nettle root: content and composition as affected by pressurized liquid extraction.

The optimal PLE conditions were 150 °C/5 min/4 cycles and showed significantly better performance compared to SE (68 °C, 8 h), proving to be an excellent technique for the isolation of the nettle root lipid fraction. Also, triterpenoid derivatives from nettle could be used as functional ingredients for the development of new foods and dietary supplements. This article is protected by copyright.
