摘要:
The invention provides a diagnostic agent for the detection of occult blood in feces comprising hydrogen peroxide and, as a chromogen, guaiaconic acid A, optionally with a stabilizer. The invention provides, as a novel substance, guaiaconic acid A having a specific extinction E.sub.1 cm.sup.1% at 600 nm of at least 200, determined by the reaction with peroxidase and hydrogen peroxide, having infra-red bands at1600 cm.sup.-1 (m);1505 cm.sup.-1 (v.s.);1206 cm.sup.-1 (s;b);1115 cm.sup.-1 (m);1025 cm.sup.-1 (m); and1200 cm.sup.-1 (s;b)and having an R.sub.F value of 0.45 (toluene/dioxan/glacial acetic acid; 90:25:10 v/v/v).
