Abstract:
Five sulfonated compounds, namely 4-gingesulfonic acid and shogasulfonic acids A, B, C and D, were isolated together with seven known compounds including 6-gingesulfonic acid from Zingiberis rhizome (Japanese name: Shokyo) made out of ginger. Their structures were characterized by means of spectroscopic analysis.
