Abstract
The present invention relates to a 2-aminoethanesulfonic acid zinc complex represented by the following formula: ##STR1## (wherein M is an alkali metal atom), to a process for producing the said complex from 2-aminoethanesulfonic acid and to use of the said complex as an anti-hepatitis agent, liver function improving agent and anti-ulcer agent. The said complex exhibits not only improved physiological activities such as anti-hepatitis activity, suppressory activity against liver-function disorder and anti-ulcer activity but also protective and restorative activity for the digestive tract.
