摘要

Compound of the formula CHEM in which R and R min represent hydrogen or an optionally substituted hydrocarbon radical or acyl radical, R1 represents hydrogen or an optionally substituted hydrocarbon radical of aliphatic or aromatic character, R2 represents hydrogen or an optionally substituted hydrocarbon radical of higher aliphatic or aromatic character, it being possible for R1 and R2 together to represent also an optionally substituted alkylene radikal or an optionally substituted biphenyl-2,2 min -ylene radical, whereby however, when R, R1 and R2 are hydrogen, R min cannot be methyl and salts of such compounds that contain a saltforming grouping, and pharmaceutical compositions containing these compounds. The pharmaceutical compositions containing these compounds are particularly valuable for treating liver and venous diseases.
