Gastroprotective extracts of Sonchus oleraceus L.

摘要

The gastroprotective extracts of S. oleraceus L. are ethanol extracts (including the initial ethanol extract and serial extractions of the marc in ethanol), which are concentrated at low temperature to obtain a gummy residue that is dissolved in water. Lipoidal compounds are removed from aqueous extracts by filtration, and serial extracts proceeding from the aqueous extracts using chloroform to obtain low polarity phenolic compounds and n-butanol to obtain high polarity compounds and any remaining compounds. These extracts may be used to treat conditions of the stomach and colon including preventing peptic ulcers and treating ulcerative colitis.
