Abstract
The isolation of shikimic acid from star aniseed is described. This experiment uses Soxhlet extraction followed by ion exchange chromatography to isolate crude shikimic acid from the star aniseed. Subsequent charcoal decolorization and recrystallization from toluene and methanol afford the pure shikimic acid in 2–7% w/w yield.
